Based on the distributed energy technology, MicroGrid has caused wide attention. It is of great significance to solve the problem of electricity generation in rural areas by establishing an independent MicroGrid system, which mainly consists of solar energy and wind energy. It becomes crucial to find a way to optimize the structure of MicroGrid according to various energy situations. Based on the analysis of the general structure and operation modes of MicroGrid, a hybrid power model, which containing photovoltaic power system (PV), wind power system (WT) and energy storage battery (BATT), has been established in this article. The optimization model and corresponding calculation method not only provide an innovative research method, but also contribute to the further research and application on design methods and operation modes of the distributed MicroGrid system. According to the model established in the article, a MicroGrid system of a village scale has been analysed as an example. With the help of MATLAB Software, the branch and bound algorithm is used in order to minimize the cost of MicroGrid. The optimal installed capacity of PV, WT and BATT is presented. The generating cost per kWh and power supply reliability are demonstrated in this article as well.
