To install the reactive power compensation in grid connection point is an effective method to improve the voltage stability of wind power and ensure reliable operation. This paper designs a kind of STATCOM with superconducting magnetic energy storage. It achieves system decoupling of the feedback linearization using the inverse system method, and then controls the decoupled inverse system based on the RBF neural network sliding mode control. Simulation results show that the inverse system method and RBF neural network sliding mode control show a good effect in improving the system dynamic response speed and the system robustness. The results accord with the dynamic response characteristics of STATCOM with SMES.
