Renewable energy sources are widely used these years for they have many advantages. To transform renewable energy into electrical power, the microgrid is used. Microgrids are suitable in distributed power generation. Traditional synchronous generator offers voltage and current supports to maintain the stabilization of power grid. The aim of project is to set a VSG-based microgrid system. The VSG is used to mimic the properties in microgrid to keep the system work stably. First, the FYP introduces VSG with LC filter. Then the controller system is designed, including frequency system, current and voltage system. With controller system, the output deviation of system is successfully controlled in an acceptable range. In the end, the model is set in Simulink, and the result shows that the VSG in microgrid keeps the system inertia and the frequency deviation in a normal range. The plan is proved feasible through the experiment.
