Self-adaptive control strategy of wind-hydrogen coupling system considering hydrogen storage pressure
摘要
Abstract
To address the frequency fluctuations and exceeding limits caused by load changes when wind hydrogen coupling system is connected to the weak current grid,a grid type virtual synchronous generator(VSG)moment of inertia self-adaptive control strategy based on dynamic feedback of hydrogen storage system pressure is proposed.Firstly,a physical simulation model of the grid type wind hydrogen coupling system is established,the closed-loop transfer function of active power is derived,and the influence of rotational inertia and damping coefficient on the power frequency oscillation characteristics of the system is analyzed.Then,considering the dynamic changes in pressure of the hydrogen storage system,the moment of inertia calculation is optimized in real time to ensure stable operation of the wind hydrogen coupling system under grid frequency fluctuations and load active power fluctuations.Finally,the strategy is validated using MATLAB/SIMULINK platform.The results show that,using the grid type self-adaptive method can accelerate the frequency recovery of the system,significantly improve the dynamic response ability of the system,and achieve stable operation of the wind hydrogen coupling system.关键词
