The operating method of micro-grid including distributed power

Among researches in the use renewable energy resources, the study is actively in progress about micro-grid system applied DC distribution. Wind and photovoltaic (PV) sources which used at micro-grid as distributed power have flexible generation. When comparing with flexible generation curve and demand load curve, the produced power of micro-grid has deficient or excess case. So, Only pure generation of solar and wind turbine is hard to achieve stable power supply. Because of these reason, operating methods need for stable power supply. This paper analyzes the daily pattern of power and presents the operating methods of micro-grid consist of PV module and wind turbine. Also, the operating method checked through simulation.
