10 System Design: The Components of Success. Our success lies in the system. All components are optimally tailored to their functions. The 2.5 MegaWattBlock is a consistent power plant unit developed for the construction of solar power plants in 2.5 MWp steps. The BELECTRIC system design is characterized by its intelligent combination of high-quality components. Specially developed materials ensure decades of reliable operation, even in extreme environmental conditions. The block design of the successful BELECTRIC product series sets new standards: with its help, it is possible to reduce the levelized costs of electricity even further. power control devices, the PCU is designed to provide reactive power to the full extent of its rated power and to react dynamically to grid voltage deviations - with a power loss lower than 1%. Also the fact that the reactive power control works even without sunlight is a benefit of the BELECTRIC power plant technology. Optimize the economic viability of your investment in solar energy with the new 2.5 MegaWattBlock. The advanced Power Conditioning Unit (PCU) with built-in reactive power control ability helps to improve the stability of the local grid network. Compared to traditional reactive 10

13 Power Plant Controller (PPC) The intelligent control unit monitors the grid access points and regulates the electrical current flow of the solar power plant and adjusts the voltage using reactive power. Specially developed voltage sensors and software algorithms detect emerging grid requirements and react automatically. Reliable support for the local grid. With the Real-time Management system all grid access points and solar power plant data are permanently available to be monitored. The web interface offers a huge variety of logging and analyzing tools. With the extensive analysis and logging functions, you always have data on the solar power plant output with all its parameters at hand. This basic data makes it possible to avoid system failures and to increase operating safety. Power Conditioning Unit (PCU) The specially developed Power Conditioning Unit (PCU) includes an intelligent inverter system with up to 1500V DC system voltage and a transformer station. The inverter system is optimized for the use of thin-film module technologies and is characterized by the high level of system efficiency. The built-in PID protection device reduces the module degradation effect. A typical public grid shows many voltage deviations produced by different power loads. The dynamic reactive power capability of the PCU stabilizes the public grid voltage - day and night. The PCU with its medium-voltage grid supply in outdoor construction enables optimum accessibility and easy maintenance of the system.

14 New Technology: For a Stable Power Grid. The existing power grid was originally designed as a distribution grid: large power plants produce power centrally at high and highest voltage levels for consumers at a lower voltage level. This concept endured unchanged for almost 100 years. However, the installation of renewable energy sources over the past decade has brought about the addition of energy generators at low and medium voltage level. The result: a significantly more complex, distributed grid structure. With the 2.5 MegaWattBlock, BELECTRIC provides the electricity suppliers with an essential component for sustainably stabilizing the power grids. The solution is an intelligent control unit that can be used to smoothly integrate the new product range into the worldwide power grids and to combine them with conventional power plants. Thus, this new technology contributes significantly to the improvement of the grid stability for operators and consumers, establishes photovoltaics as decisive part of the energy mix, and makes the costly extension of the power grids redundant.

15 Depending on the corresponding country-specific specifications, the voltage in the public power grids must be maintained in a voltage corridor so that electrical loads are not damaged. Furthermore, fluctuations should be minimized in order to allow for smooth operation. The reasons for voltage deviations are fluctuating feed-in of renewable energies and unforeseeable consumer loads. Grid stabilization by means of reactive power control The reactive power is an electrotechnical variable caused by a phase shift of the current intensity regarding the electrical voltage. The reactive power occurs everywhere in the power grid, is a necessary element for the current flow, and has a significant influence on the grid voltage. BELECTRIC uses this effect and is able to reduce the share of reactive power in the power grid on the one hand, and to increase the aforementioned deliberately on the other hand. This intervention results in the option of changing the mains voltage as required and with low electrical loss (<1%) Germany, energy generation plants must provide reactive power during normal operation in order to compensate the deviations in voltage they re causing. At this point, BELECTRIC goes the extra mile, to stabilize the regional power grid actively opposed to traditional reactive power control units: The reactive power is available independently of the solar irradiation during the day and at night. The reactive power is controlled to the full extent of the connected power of the plant. The reactive power control can be adapted within milliseconds between cos φ > 0 (inductive) to cos φ > 0 (capacitive). The reactive power control unit can be either run in automatic mode (within the power utility companies parameters regarding the local grid requirements) or in semi-automatic mode accessible by an active external control signal :00 7:00 8:00 9:00 10:00 11:00 12:00 13:00 14:00 15:00 16:00 Currently, rather different grid connection directives and requirements are applicable in the countries.
