The Optimization of Power Smoothing Control Strategy for Wind Farm Based on Flywheel Energy Storage Device

Abstract:

The instability and intermittency of wind makes the output power of the wind turbine randomness and volatility. Due to its fast pulse response and high charge-discharge rate, the flywheel energy storage can effectively reduce the power fluctuations caused by the wind farm. This article optimized the control strategy for the permanent magnet synchronous motor (PMSM) based flywheel energy storage system to reduce the active power fluctuations. Fuzzy inference method is used to make the desired smoothing active power value more precise. The rotor flux oriented vector control strategy with improved proportional resonant controller (PR controller) is proposed based on the mathematical model of PMSM to improve the robustness of the system in current control.
