DHYBRID and Vibran complete largest microgrid in Colombia
PRESS RELEASE
DHYBRID and Vibran complete largest microgrid in Colombia
Supply security for remote region
Ungía (Colombia)/Gauting (Germany), December 15, 2021. In the Colombian municipality of Ungía, DHYBRID and its regional partner, Vibran, have installed the largest hybrid microgrid in the country. This isolated community in the Chocó Department is not accessible by road. Until now, supply was restricted to 8 hours a day and was provided by diesel generators. Thanks to the new microgrid, over 10,000 families now have a reliable power supply around the clock.

The new grid is controlled and monitored by DHYBRID’s manufacturer-independent and technology agnostic Universal Power Platform (UPP). This energy management system connects four generators with a 780 kWp solar system and a 333 kWh power storage unit with a maximum output of 122 kW.
CO2 emissions cut by 818 tons per year
In addition to eliminating 818 tons of CO2 emissions from diesel generators per year, the microgrid also reduces exhaust emissions and fine dust pollution at the local level. The total fuel savings amount to 328,000 liters, not including the energy for the cumbersome transportation of diesel fuel through the jungle by boat.
Miguel Lotero Robledo, Deputy Minister of Energy, personally inaugurated the microgrid. The new system was funded through a government program aimed at supplying remote areas with green energy.
Commissioning via remote access
During the construction phase, the team faced a number of challenges including the transportation of components to the region. On top of that, the coronavirus pandemic meant that the engineers from DHYBRID were not able to travel from Germany to Colombia. These challenges were solved through close cooperation between the local experts and DHYBRID engineers in Germany: The system was installed by Vibran’s on-site team and configured and commissioned from Germany.
“The project shows how a gradual expansion of renewable energy supply in Latin America can succeed: Operators and energy suppliers remain flexible through a technology agnostic energy management system. They can benefit from the best solution available at the moment of implementation but remain open to extend their capacities regardless of manufacturers and technology. This way they can optimally adapt the output of grids to a growing demand in the future,” explains Tom Fricke, Head of Energy Storage at DHYBRID. DHYBRID is already planning three more projects in Colombia.

PRESS RELEASE
Zimbabwe’s Largest Tea Producer Implements Microgrid from DHYBRID and Blockpower
Project to be showcased at EM-Power in Munich, Germany, October 6-8, 2021
Harare (Zimbabwe)/Munich (Germany), September 30, 2021. Tanganda Tea Company Limited, Zimbabwe’s largest tea producer and one of the largest on the African continent, uses its own microgrids at Tingamira and Jersey sites for secure and environmentally friendly energy supply since July 2021. The system consists of a megawatt-class solar plant, a lithium-ion energy storage system, and three diesel generators. It was implemented by DHYBRID and its partner, South African renewable energy specialists Blockpower. In addition to tea and coffee, avocados, and macadamia nuts are grown on site.

“Sustainable production across the value chain is becoming increasingly important for companies like Tanganda. This includes a climate-friendly and reliable energy supply. Solar hybrid systems are an ideal solution for this: They minimise CO2 emissions and reduce operating costs at the same time,” says Tom Fricke, Head of Energy Storage at DHYBRID.
Payback Time Is Three to Four Years
The region in eastern Zimbabwe is remote and difficult to reach. By reducing diesel consumption and high transport costs, the investment in the new technology will pay for itself within three to four years. Compared to the previous energy supply, which relied on diesel generators and the unstable public power grid, CO2 emissions are reduced up to 6,000 tons per year.
DHYBRID’s energy management system, the Universal Power Platform (UPP) controls all major components: the 2.6 MWp PV system, a lithium-ion storage system with 980 kWh capacity and an output of 1,000 kW as well as several diesel generators used for back-up supply.
The system is designed to be scalable and can be expanded at any time to include additional energy generators and storage. The integrated SCADA solution allows the overall microgrid to be monitored and controlled, further consumption levels are displayed in real time.
“Here in Africa, we often have to deal with very heterogeneous energy systems that are moreover growing gradually. For this, we need a technology-open and very flexible energy management system,” says Kyle Bohnsack, Director of Blockpower. “DHYBRID’s UPP is an ideal solution that we can leverage through our regional expertise.“
DHYBRID will showcase the project from October 6-8, 2021, at EM-Power in Munich, Germany, booth B5 552.

Somaliland: Solar Power and Microgrid Intelligence for an Urban Power Grid
PRESS RELEASE
Somaliland: Solar Power and Microgrid Intelligence for an Urban Power Grid
DHYBRID Technology Improves Supply Security to City and Port of Berbera
Berbera (Somaliland)/Gauting (Germany), June 22, 2021. As of April 2021, the citywide power grid supplying the city of Berbera, home to the largest port in the area, is being monitored and controlled using DHYBRID microgrid technology. For this purpose, two solar plants with a total capacity of 8 megawatts, a containerized lithium-ion power storage system with a capacity of 2 megawatt hours, and three modern diesel generators were combined in the Berbera Electricity Company (BEC) utility grid. This has enabled BEC to reduce the electricity tariff in Berbera which is now the lowest in the Somaliland and the Somali-Peninsula overall.
You can find press images here: https://www.dhybrid.de/en/press-article/somaliland-solar-power-and-microgrid-intelligence-for-an-urban-power-grid
With the help of its international partner teams and remote commissioning, DHYBRID was able to complete this large-scale expansion in just six weeks, despite the ongoing pandemic and extensive global logistics challenges.
High Energy Prices and a Boom in Solar Installations
Somalia and the Republic of Somaliland are among the countries with the highest energy prices in the world. The electrical power generation system primarily consists of isolated city grids of diesel generators. At the same time, demand for electrical energy only continues to grow as infrastructure rapidly expands. The port of Berbera, for example, is envisioned to improve the flow of goods to Ethiopia with its more than 100 million inhabitants, and is currently being expanded at a cost of almost half a billion dollars. Additionally, Berbera has its own airports to which BEC also supplies power.
In order to improve the energy supply, more and more photovoltaic power plants are being built in Somaliland to supplement the existing generators, in addition to other measures. But this development poses major challenges for the power grids. “Various generators within the grid must be continuously coordinated, especially when renewable energies are involved. Otherwise, problems with the grid frequency and voltage will become unavoidable, making it impossible to utilize all the available power,” explains Benedikt Böhm from DHYBRID. “It is simply not enough to just consider the solar capacity available. Effective grid management is essential.”
Universal Power Platform Coordinates Decentralized Generators
“The requirement was clear: Berbera needed a scalable energy supply that could be monitored and managed centrally within the shortest time frame possible. The DHYBRID Universal Power Platform has succeeded in both, power quality and grid performance have increased considerably as soon as everything was up and running,” says Ibrahim Yaqub, CEO of BEC.
In fact, Berbera’s overall city grid’s power factor has now increased by 20 percent. This has significantly improved the distribution load bearing capacity and power generation efficiency. Moreover, the discontinued use of large quantities of diesel fuel has made Berbera the largest city powered by renewable energy in Somaliland. What is more, the city now operates the largest battery energy storage system in the country.
BEC now uses DHYBRID’s open-technology Universal Power Platform (UPP) as a process control system and monitors its energy grid with the SCADA system from the very same microgrid specialists based in Germany. SCADA stands for Supervisory Control And Data Acquisition. It is a computerized system for monitoring technical installations.
DHYBRID’s lithium-ion storage system can be operated either alongside the grid or as an integrated part of it. In this operating mode and in conjunction with the UPP, it almost completely eliminates grid instability and disturbances due to multiple effects of growing electrical demand profiles.
This project in Somaliland is one of the first in the world to use DHYBRID’s patented Maximum Inverter Power Tracking (MIPT) technology to increase the share of solar power in microgrids.

DHYBRID installs connected microgrids on 26 Maldivian islands
PRESS RELEASE
DHYBRID installs connected microgrids on 26 Maldivian islands
Central monitoring through a shared SCADA system
Gauting (Germany)/Malé (Maldives), June 8, 2021. Microgrid experts at DHYBRID have installed microgrids on a total of 26 islands on the Shaviyani and Noonu Atolls of the Maldives and equipped them with a central monitoring and control system (SCADA). The project sponsored by the Maldivian Ministry of Environment and the Climate Investment Funds aims to substantially decrease carbon emissions as well as the costs of energy generation on these remote islands. The solar energy capacity installed is about 2.65 megawatts, and the capacity of the battery storage systems used is around 3.2 megawatt hours.
You can find press images here: https://www.dhybrid.de/en/press-article/dhybrid-installs-connected-microgrids-on-26-maldivian-islands
The solar addition to the existing microgrids on both atolls is part of the Preparing Outer Islands for Sustainable Energy Development project, or POISED, which sees to making the energy supply of the outer atolls and islands as well as the region surrounding the main island of Malé sustainable.
Objective: Reducing high electricity prices and emissions
Almost all electricity consumed in the Maldives is generated from imported diesel. The costs for importing energy made up about 20 percent of the gross domestic product in 2016. Transporting this electrical energy to the remote islands and atolls to the south adds to these costs on a local level. At rates of 20 to 70 US cents per kilowatt hour, the electricity prices in the Maldives are among the highest in all of Southern Asia. Plus the diesel systems have high emissions in the form of CO2, pollutants and noise. Photovoltaic installations and battery-based storage units significantly reduce the diesel generators’ run times.
The central energy management system, the Universal Power Platform (UPP), from DHYBRID is what sets its microgrids apart. The UPP dynamically controls all energy flows in the grid, from the battery inverter to the diesel generator. It also continuously measures the grid and storage system parameters as well as the load profiles and prioritizes solar energy whenever possible. Only when the combined power from the PV installation and storage system is insufficient the diesel unit switches on.
The advantages of the new microgrids are immediately noticeable. On the island of Fohdoo, a photovoltaic installation with a power output of 100 kilowatts supplies about 30 percent of the island’s electricity, saving around 35,000 liters of diesel per year. “The generator remains shut off for the majority of the day,” says Abdulla Nashith, Director of the Technical Services and Green Energy Department of Fenaka Corporation Limited, a state-owned utility company which is responsible for most of the southern atolls.
Central monitoring of all 26 islands
The new microgrids are monitored in the utility’s central monitoring stations at Fenaka’s headquarters in the Maldivian capital city of Malé. All 26 islands are centrally monitored by a SCADA system developed by DHYBRID. Access is granted via a secure, encrypted VPN connection. “From Malé, we can monitor energy generation and other parameters on the other islands in real time thanks to the centralized SCADA system. This enables us to respond quickly to any problems that occur,” Nashith adds. New solar-diesel hybrid grids are in the pipeline in the next several years for 69 more Maldivian islands. They will also be linked to the central SCADA system.
In addition to supplying components and connecting the system, DHYBRID also trains local personnel to operate it. “DHYBRID has a wide range of experience, with over 70 projects worldwide. Most of the microgrids in use in the Maldives rely on our technology. We transfer this knowledge to our partners as part of our training programs so that they can continue to operate the installations as efficiently as possible,” says Benedikt Böhm, CEO of DHYBRID.

Patented new DHYBRID technology lowers costs and increases the proportion of solar power in microgrids
PRESS RELEASE
Patented new DHYBRID technology lowers costs and increases the proportion of solar power in microgrids
Dynamic inverter control system ensures higher yields and compensates for inverter failures
Munich/Germany, 26 November 2020: The microgrid specialists at DHYBRID have introduced a new technology that lowers energy costs for stand-alone grids by achieving significantly greater solar yields. Simply by improving system management, the recently patented inverter control system can increase the proportion of solar power by more than 10%, with corresponding reductions in the amount of power required from diesel generators or other connected power grids. The Maximum Inverter Power Tracking (MIPT) system achieves these results by continuously adjusting the output of individual inverters or groups of inverters in accordance with the needs of the microgrid.
An infographic is available here: https://www.dhybrid.de/en/press-article/patented-new-dhybrid-technology-lowers-costs-and-increases-the-proportion-of-solar-power-in-microgrids
Higher yields from new and existing systems
Conventional microgrid control systems treat all inverters the same, assigning them an identical maximum feed-in rate – which could be a fixed percentage of their nominal capacity. This means that within a microgrid, PV systems that are producing high yields at any given time are treated the same as those that are not performing as well. The resulting power output losses are entirely avoidable and can have significant effects for microgrids in particular. Microgrids often comprise several PV systems that are all connected but may experience different degrees of shading, for instance.
The MIPT system ensures optimal control by continuously monitoring the outputs of the various PV systems, thereby allowing the maximum feed-in capacity to be dynamically distributed across all connected inverters several times per second. Systems that are running better can feed in more energy, making it possible to take full advantage of the photovoltaic output.
“A similar approach has been used to optimize performance between the PV module and inverter. Our technology takes this to the next level and optimizes the performance of individual inverters within a hybrid system. This allows us to significantly improve efficiency and increase potential savings,” explains Tobias Reiner, CTO at DHYBRID.
“In some cases, we have been able to increase the proportion of PV in our systems by more than 10%,” Reiner adds. To save costs, the new technology relies solely on the MIPT algorithm in the DHYBRID software. Since neither special inverters nor other energy producers are needed, the innovative solution can be used to optimize both new and existing systems.
A positive side effect of employing the dynamic inverter control system is that the output of connected diesel generators does not need to be adjusted as often. When generators run steadily, their efficiency and service lives improve, an effect that is clearly evident in the substantially smoother feed-in curves.
Especially beneficial when inverters fail
The operating principle and the advantages of the new control system become even clearer when an inverter fails. Conventional approaches would treat the defective inverter as if it were still functional, even though it can no longer deliver any yields. By contrast, the MIPT system assigns the remaining systems a higher maximum output power so that they automatically compensate for part of the shortfall.

Visionary electricity supply for traffic management center and highway maintenance depot
Press Release
Visionary electricity supply for traffic management center and highway maintenance depot
ASFINAG, DHYBRID and K.E.M. MONTAGE implement renewable, fail-safe microgrid
Munich/Klagenfurt, 10 March 2021 – The Austrian highway financing corporation ASFINAG has joined forces with its long-time service partner and general contractor K.E.M. MONTAGE as well as DHYBRID, the German microgrid specialists to create a visionary, future-oriented electricity supply for one of the most important traffic management centers and highway maintenance depots in Austria. To achieve this, the organizations have constructed a “hybrid microgrid” at the Klagenfurt highway maintenance depot. This microgrid supplies uninterrupted renewable energy to the entire site, even when the public grid experiences power outages. The Klagenfurt highway maintenance depot’s responsibilities include the monitoring and maintenance of various tunnels through the Alps as well as the well-traveled Tauern Autobahn highway.
You can find press images here: https://www.dhybrid.de/en/press-article/visionary-electricity-supply-for-traffic-management-center-and-highway-maintenance-depot
The project’s role in the ASFINAG sustainability strategy
The highway maintenance depot in Klagenfurt is supplied with solar energy as part of ASFINAG’s plan to gradually switch all company’s locations over to green power. The integrated energy storage system ensures that solar energy generated by day can also be used at night or in the event of grid failure. Until now, such an uninterrupted power supply involved considerable additional technical overheads. Yet this power supply is responsible for making sure that tunnels and sections of highway can continue to be monitored even if the public power grid fails.
“The Klagenfurt highway maintenance depot’s microgrid goes to show that renewable energy and a reliable energy supply go hand in hand, assuming the right technological steps are taken. Thus, the new energy system is more than just a flagship project – it is a real bonus in terms of driver safety,” says Christoph Lang, Head of the Renewable Energy & E-Mobility Department at K.E.M. MONTAGE, the general contractor for the construction of the new power system.
Secure energy supply with the hybrid microgrid
Hybrid microgrids refer to small-scale, local power grids which are connected to the public electric grid. If necessary, they also function in island operation, being independent of the public grid, typically with the help of a battery storage system and specialized electronics.
The Klagenfurt highway maintenance depot’s hybrid microgrid combines a 220-kWp photovoltaic installation with a 522-kWh lithium-ion storage system. The Universal Power Platform (UPP) energy management system from DHYBRID controls and monitors all of the energy supply parameters. If the public grid fails, the battery storage system will seamlessly take over the supply to the microgrid with the support of the UPP.
Once the public grid is back in operation, the UPP measures the necessary parameters and ensures that the microgrid is seamlessly resynchronized to the grid for parallel generation. Under battery operation, the UPP also regulates the load management for three connected charging stations with up to 70 kW for electric vehicles belonging to ASFINAG. If the energy storage system’s capacity is completely exhausted due to a lasting power outage, the UPP will switch on a back-up diesel generator fully automatically.
About DHYBRID
DHYBRID originally developed its microgrid technology for use outside of Europe, for instance in remote areas which cannot reliably be supplied by a stable electricity connection. But the expansion of renewable energy and the increasing demand for customized energy storage solutions have paved the way for increased use of DHYBRID microgrids in Europe as well.

PRESS RELEASE
DHYBRID implements fail-safe grid concept for Sri Lanka’s leading utility company
NETWORKED MICROGRIDS ENSURE THAT RENEWABLE ENERGY IS AVAILABLE AREA-WIDE
Munich/Germany, Colombo/Sri Lanka, 22 October 2020: The off-grid experts at DHYBRID have taken a pioneering approach to the power grid in Sri Lanka. Their pilot project connects stand-alone grids to ensure a fail-safe supply of renewable power that can be utilized throughout the distribution area and expanded at any time. In the first stage of the project, DHYBRID is collaborating with its local partner DIMO to establish a grid-connected microgrid. The client is Sri Lanka’s leading utility company, Lanka Electricity Company (LECO), with power being supplied to the campus of the University of Moratuwa, Sri Lanka’s renowned technical university.
You can find press images here: https://www.dhybrid.de/en/press-article/dhybrid-implements-fail-safe-grid-concept-for-sri-lankas-leading-utility-company
The hybrid microgrid relies on DHYBRID’s Universal Power Platform energy management system as well as the company’s battery energy storage system, which offers 400 kWh of capacity and an output of 400 kW. Power is generated by four roof-mounted solar systems with a combined output of 350 kWp. A diesel generator is reserved for exceptional circumstances.
Automatic compensation for fluctuations
DHYBRID’s hardware and software solution controls all local power generators, manages key electrical loads and avoids disruptions to the grid. Together with the storage system, it automatically compensates for fluctuations in renewable power generation, thereby increasing the autonomy of the local microgrid. Since a significant proportion of locally generated renewable energy is consumed on-site, only minimal amounts of electricity must be drawn from the national power grid. This approach also relieves strain on the public grid by using load management to ensure a more constant feed-in of surplus renewable energy.
Network of grid-connected microgrids provides security
In order to implement the microgrid concept across a broader area, additional grid-connected microgrids are planned. Connecting these microgrids to both the public grid and one another will create a supply system that maximizes local energy use while also preventing area-wide power failures.
The innovative concept of connected microgrids offers several advantages over a power system that lacks access to independent sub-grids: “For one thing, it is easier to coordinate consumers and producers of renewable energy in small-scale, local grids than in a centralized system,” explains Fabian Baretzky, regional manager at DHYBRID. “For another, if there is a power outage, the individual microgrids disconnect from the public grid to provide uninterrupted on-site power. This offers operators a high degree of stability and saves them money.”
If the public grid fails, the DHYBRID Universal Power Platform (UPP) automatically opens the mains breaker, which creates a local stand-alone grid managed by the UPP without interrupting the power supply. When the system detects that the public grid is available again, it measures the necessary parameters and resynchronizes the battery inverter, before seamlessly reconnecting the microgrid to the public grid.

DHYBRID presents new storage solutions for hybrid power plants and microgrids
Uninterruptible power supply for regions with challenging climates
Munich, Germany, 10 December 2019: DHYBRID — the specialist in hybrid power plants — is enhancing its hardware and software portfolio with microgrid-optimized lithium-ion storage solutions. The new storage systems work seamlessly together with DHYBRID’s Universal Power Platform (UPP), which controls the interaction of solar systems, storage units and diesel generators in local power grids. In combination with the UPP, the storage systems allow for a truly uninterruptible power supply. Such supply is necessary when computers or devices must be prevented from losing power during problems with the grid, for example. This sets the solution apart from a conventional storage-supported back-up power supply, which can sometimes still experience brief interruptions.

Special requirements for storage systems in hybrid microgrids
Unlike conventional energy systems, hybrid microgrids must be able to switch seamlessly between different energy sources. This also changes the master and slave roles in the system and places special demands on the control system and on storage-relevant components such as the battery inverter.
“We adapt the configuration of our storage systems individually to each project in order to optimize them for the respective Microgrid. We use data from more than 70 projects that our team has been working in more than 20 countries. The UPP, which orchestrates the components in the system, ensures the necessary flexibility and the technology-agnostic approach,” says CEO of DHYBRID Benedikt Böhm.
Customizable all-in-one solution
The new storage solutions are installed in 10-, 20- and 40-foot air-conditioned containers and can be seamlessly monitored using a SCADA system with VPN access, making them particularly suited to guaranteeing supply security in areas with no grid connection or with a challenging climate. The storage capacity is between 100 kWh and several MWh, with a charging and discharging rate of up to 2C.
The systems use high-quality lithium-ion cells from manufacturers such as Samsung and LG, depending on the performance required as well as the area of application. These manufacturers also provide battery management to ensure safe control of the battery cells and modules to the highest possible standard in all operating states. The integrated battery inverter, too, is custom-planned and specially configured for each project.
Success story in Africa
The new storage system can be seen in use at South Africa’s Kruger National Park. This particular system has a capacity of 1 megawatt-hour and works together with three solar installations with a combined output of 300 kW as well as a 150-kVA diesel generator to supply the Cheetah Plains Lodge’s microgrid with three-phase electric power. DHYBRID’s Universal Power Platform (UPP) monitors and controls all important grid parameters and enables automated system operation. The project was realized in collaboration with DHYBRID’s local partner Blockpower.

Focus Topic “Flexible Sector Coupling” at the ENERGY STORAGE EUROPE Conferences
Focus Topic “Flexible Sector Coupling” at the ENERGY STORAGE EUROPE Conferences
Köln, 1.March 2019 - At this year's ENERGY STORAGE EUROPE Conference, as well as at the parallel International Renewable Energy Storage Conference (IRES), flexible sector coupling will become the focus topic: innovative mobility solutions with power-to-gas technologies, storage technologies for efficient charging infrastructures and cross-sector thermal storage solutions are exemplary keynote matters.
Energy storage systems of growing importance to the grid
The importance of the system-supportive use of energy storage systems continues to grow. Storage applications optimize supply security and enable decarbonisation of the energy system. With the help of energy storage systems, the increasing demand for power can be met and the decentralisation of the energy system can be realised efficiently. "Politicians recognise the relevance of storage facilities for decarbonising a secure supply system. The advancement of power-to-x technologies, such as green hydrogen production, is an important approach here," comments Urban Windelen, Federal Managing Director of BVES, on the latest political signals.
Power-to-X: Focus Session at the Conference
The IRES conference of ENERGY STORAGE EUROPE focuses on both research projects and concrete application examples within the area of Power-to-X. The ESE Conference offers a top-class lecture program with the Power-to-X Workshop led by Dr. Christopher Hebling.
Hydrogen pioneer Mortimer Schulz will be driving a hydrogen car to the ENERGY STORAGE EUROPE, testing the available hydrogen refueling infrastructure on the road. During his presentation, taking place in the Forum of the fair on 13 March 2019 at 4.05 pm, he will discuss new business models based on hydrogen production, storage and transport.
The multi-use trend at ENERGY STORAGE EUROPE
Multi-use models are a key trend in the storage industry. A large number of examples will be presented at ENERGY STORAGE EUROPE. The BVES explains the concept of multivalent storage models using the BVES pocketknife principle: "Multi-use storage models function according to the Swiss army knife principle: a storage technology can be used as a tool for various applications. Peak load shaving, uninterrupted power supply, emergency power supply as well as the replacement of diesel generators. Individually and especially in combination, the applications quickly lead to a very economical use of storage systems," says Urban Windelen, Federal Managing Director of the German Energy Storage Association (BVES).
