Abstract

It is an important goal of the microgrid control system to realize the rational allocation of power between the AC and DC microgrid by using the power electronic converter to integrate the renewable energy into the power distribution system. This paper introduces the Virtual Synchronous Generator (VSM) control strategy of hybrid microgrid, which solves the above problems by mimicking the characteristics of traditional Synchronous Machine (SM). In order to better optimize the performance of AC/DC hybrid microgrid, a novel VSM-based bidirectional converter (BC) control strategy is proposed, which also ensures the capability of BC independent power allocation. Finally, in the PSCAD environment, two types are used. The hybrid microgrid with different BC control structures was studied and compared.
