英文摘要：

Existing methods to determine the battery bank capacity of microgrid composed of wind power, photovoltaic （PV） generation and energy storage device are classified and summarized. In the viewpoint of implementing continuous power supply by independent microgrid composed of wind power, PV generation and energy storage device, the method for optimal configuration of battery bank capacity is researched. In allusion of the defects in traditional method and integral method, in which the restriction of operating characteristic of battery bank its own are not taken into account, considering internal characteristic of battery bank a method to determine battery bank capacity based on the modeling of battery bank is proposed, and according to the differences of optimization objectives and constraints, three different optimization schemes are built. Similarities and differences among the methods mentioned in the paper are given by concrete calculation examples, and the effectiveness of the modeling method based on internal characteristic of battery bank is verified by comparative analysis. After the discuss in depth, suggestions on optimal configuration of battery bank capacity in independent microgrid composed of wind power, PV generation and energy storage device are put forward.
