Abstract

To mitigate the discrepancies between actual wind power output and day-ahead forecasted power, and to alleviate the heightened pressure on grid dispatch and operation caused by wind power uncertainty, a control strategy for a wind-hydrogen hybrid power generation system is introduced. This strategy aims to minimize tracking errors and smooth power output fluctuations. It integrates fuzzy logic control （FLC） and model predictive control （MPC） algorithms, leveraging the robustness and real-time benefits of FLC with the anticipatory optimization capabilities of MPC. Initially, the membership function parameters of the FLC are optimized iteratively using MPC. Subsequently, the optimized parameters are applied to the fuzzy controller （FC） in the next time step. Simulation results demonstrate that the FLC-MPC strategy significantly enhances regulation performance for the wind-hydrogen hybrid power generation system. In comparison to FLC alone, the root mean square error （RMSE） is decreased by 4.03%, maximum power fluctuation is reduced by 23.17%, penalty energy is diminished by 14.98%, and the continuous regulation capacity of the hydrogen energy storage system is improved by 11.58%.
