Research of Virtual Synchronous Machine Control Strategy of Hybrid Renewable Energy in Microgrid

Abstract

With rapidly use of energy internet, more and more research focus on microgrid with hybrid renewable energy in recent decades. In this paper, research of virtual synchronous machine (VSM) control strategy of hybrid renewable energy in DC microgrid is put forward. Mode and topology of key devices are given, a virtual governor and a virtual excitation regulator are also designed to make sure that the grid control center can dispatch microgrid with the same way as dispatching synchronous machines. At the end, a simulation model of VSM control strategy of hybrid renewable energy in DC microgrid is created in Simulink platform, the site operation results shown the high performance of the designed VSM control strategy.
