| Abstract: | In the background of Tibet Cuoqin multi-energy complementary isolated microgrid demonstration power plant project, the microgrid characteristics are presented together with the system scale and composition consisting of wind turbines, photovoltaic, diesel generator, battery energy storage and hydropower. The operating characteristics of hydroelectric generating units as well as the voltage source inverter based on virtual synchronous generator(VSG)are analyzed. Besides, both the synchronization device and the zero-initial voltage boosting time of VSG are optimized to guarantee seamless switching in different system operation modes. Additionally, the power supply modes and operation process of the multi-microgrid system are demonstrated in detail. Finally, field tested results of the microgrid are utilized to confirm the feasibility and effectiveness of the proposed control strategy.
