Dynamic Optimization of Wind - Energy Storage Combined Frequency Modulation System Based on Improved Energy Storage Control

With the increasing penetration of wind power, power systems demand enhanced frequency regulation capabilities from wind-energy storage systems. Aiming at the frequency stability problem caused by the high - proportion integration of wind power, an improved energy storage sub module control strategy is proposed. By adding a PI controller, optimizing its parameters, and introducing a saturation - limiting link, the system frequency fluctuation is effectively suppressed, the frequency response speed is increased,the economic viability of energy storage integration in wind power frequency regulation is significantly enhanced. Simulation results indicate that the optimized system can rapidly react to load fluctuations, demonstrating improved operational stability and heightened steady-state precision. These findings effectively validate the proposed scheme’s efficacy in enhancing dynamic response and system reliability.
