Synchronization Stability Analysis and Control of Renewable Energy Generation Connected to the Grid Through Power Electronic Converters

In recent years, the installed capacity and power generation of renewable energy have been increasing continuously. The integration of large amounts of renewable energy generation into the grid brings challenges to power system stability. In this paper, the impacts of converter control strategy, impedance parameter and network topology on the synchronization stability of renewable energy generation system are explored in a single-converter infinite-bus system and a multi-converter system by using simulation method. Based on the simulation results, suggestions are given to improve the synchronization stability of renewable energy generation connected to the grid through power electronic converters.
