Mitigating The Power Fluctuation Of PMSG Wind Turbine In A Microgrid By Optimal Usage Of SMES With FCL Using PID Controller
Abstract— The major problem of PMSG wind turbine are power fluctuation. And this problem is overcome by new optimization technique and circuit model of the Superconducting Magnetic Energy Storage (SMES) with Fault Current Limiter (FCL) in a micro grid. Normally, SMES-FCL circuit which contain superconducting coil. In case of without fault condition, SMES-FCL act as the SMES unit to mitigate the power fluctuation of PMSG. Under fault condition, the SC is automatically connected to the system and it can be used as FCL to reduce the fault current. Then, the voltage drop of PMSG and fault current unit will be mitigated. By the energy function method is used to determine the optimal problem. Finally, this MATLAB result shows the superior control effect compare to the conventional method.
