본 논문에서는 점차 증대되는 신재생 에너지 비율에 따라 계통 연계형 태양광 발전 시스템에 엄격하게 요구되고 있는 규정들에 대해 독일 연방 에너지 수자원 관리 협회(BDEW: Bundesverbands der Energie und Wasserwirtschaft)의 규정을 근간으로 그에 따른 인증 시험 항목에 대해 기술하기로 한다. 또한 실제 (주)카코 뉴 에너지의 BDEW 인증 시험 자료의 일부분을 바탕으로 시험의 중요성 및 필요성에 대해 그 타당성을 입증한다.

The rising penetration of renewable energy resulted in the development of grid-connected large-scale power plants. Therefore, grid stabilization, which depends on the system-type or grid of each country, plays an important role and has been strengthened by different grid codes. With this background, VDE-AR-N 4105 for photovoltaic (PV) systems connected to the low-voltage grid and the German Association of Energy and Water Industries (BDEW) introduced the medium-voltage grid code for connecting power plants to the grid and they are the most stringent certifications. In this paper, an optimal control strategy scheme for three-phase grid-connected PV system is enhanced with VDE-AR-N 4105 and BDEW grid code, where both active/reactive powers are controlled. Simulation and experimental results of 100kW PV inverter are shown to verify the effectiveness of the proposed implemental control strategy.

The rising popularity of renewable energy sources resulted in development of the units of higher rated powers, where the large-scale plants and grid-connected type solar power systems are increased. Therefore, the importance of grid stabilization, which depends on each country or system-type, has been strengthened by different grid-codes or certifications. In this paper, the control scheme of three-phase photovoltaic system is enhanced, where both injected active and reactive powers are simultaneously controlled with the consideration of the certification of the Germany Association of Energy and Water Industries (BDEW). Experimental results are shown to verify the theoretical analysis.
