Study on power smooth control of microgrid based on energy storage system

Abstract

Abstract:

Abstract:For the power supply problems of big fluctuation and strong randomicity caused by connecting renewable energies into microgrid, this paper proposes a power smooth control method of microgrid based on energy storage system. This method takes the measured values of battery state of charge (SOC) as feedback and adjusts the time factor of smooth control method, which could effectively avoid the big power fluctuation of microgrid, stabilize the energy storage batteries SOC in the standard range and improve the service life of battery. The effectiveness of this control method is verified by established simulation model.
