As more and more distributed generations are connected to the grid, the grid is increasingly vulnerable to power fluctuations and system failures, the stability of the power system is seriously challenged. This paper proposes an optimization design method of multi-virtual synchronous generators (VSGs) control parameters of independent microgrids based on gradient descent method, and a small signal model of independent microgrids with multi-VSGs is also established. Then gradient descent method is used to optimize the multi-VSG control parameters of the independent microgrid. The simulation results reveal that the proposed multi-VSG control parameter optimization design method can effectively improve the frequency and voltage dynamic response performance and the stability of the independent microgrid under small disturbances.
