Abstract: Microgrids play a very important role in utilizing the distributed energy resources more effectively and optimizing the distribution system structure. They have the potential to improve performance in power supply diversity, reliability and quality. The key laboratory develops the dynamic simulation platform for microgrids, based on CERTS Microgrid model. The distributed power generation, operation, control and protection of microgrids were studied on the platform. Experimental  results show that the converter of the doublyfed power generation system has better controlling performance.

Key words: microgrid；dynamic simulation platform; control of photovoltaic power generation; control of wind power generation; experimental study
