Control of Power Electronic Converters for Efficient Operation of Microgrid Consisting of Multiple DG Units and ESS

Abstract

Abstract. To construct a reliable and efficient microgrid system which consists of multiple DG units, local loads, and ESS, this paper presents a control methodology of power electronic converters and their dynamic behaviors. Microgrid often exchanges the active and reactive power with main grid and needs to operate with a high degree of smartness and flexibility. In microgrid operation, the electrical power flow is mainly dependent on the generated power of DG units, load power demand, and ESS state. As main constituting elements of microgrid, this paper presents a control strategy of power electronic converters. Through the integrated simulation studies, the dynamic behaviors of power electronic converters are investigated in detail.
