A control method of microgrid based on the life model of battery

The energy storage system in microgrid can effectively stabilize the fluctuations of output power of wind power and photovoltaic, increasing the inertia of the microgrid system, to improve power supply reliability and improve power quality. On the basis of the analysis of the battery life model and control theory of micro sources, this article proposes a control method based on the life model of battery. The battery life is affected by the factors, such as the battery charge and discharge current, state of charge and temperature. When the battery's actual operating parameters is lower than the limit of life protection, can battery life extend. The method described in this article is verified by an example.
