A Micro-Grid has a small capacity of the system compared with conventional power system. When the Micro-Grid is disconnected from power system and operated under islanding condition, the problems of the power quality such as frequency fluctuation and voltage fluctuation can occur. This paper presents the "local control" method of improvement of the power quality in order to solve the problem. The suggested method is to use an inverter of a battery which is an energy storage system in the Micro-Grid and to improve frequency fluctuation and voltage fluctuation in Micro-Grid islanding operation. The impact of the method is investigated in this paper by analysis using HYPERSIM. Additionally, it is shown that the local control is developed and verified by field test in the Micro-Grid under islanding operation.
