N2 - This paper presents new approaches in order to solve problems related to clustered photo voltaic systems and evaluates the performance of the developed method. To cope with inappropriate phenomena caused by malfunctions of islanding detector and over voltages by reverse power flows from PV systems, we have developed a new islanding detector and two types of voltage control systems, and conducted experiments to verify the function of the developed systems. The test results obtained by this demonstrative implementation show that the proposed control system is able to maintain voltages within the regulated level and to equalize the efficiency in a PV system and also that the new method enables us to make total PV generation efficiency higher.
