摘要(Abstract)：

针对风氢耦合系统接入弱电网下负荷变动导致系统频率波动及越限问题，提出基于储氢系统压强动态反馈的构网型虚拟同步发电机（virtual synchronous generator,VSG）转动惯量自适应控制策略。首先建立了构网型风氢耦合系统物理仿真模型，推导有功功率闭环传递函数，分析了转动惯量和阻尼系数对系统功频振荡特性的影响情况；然后考虑储氢系统压强的动态变化实时优化转动惯量的计算，保证风氢耦合系统在电网频率波动及负荷有功波动下稳定运行；最后通过MATLAB/SIMULINK进行策略验证。研究结果表明：采用构网型自适应方法可加快系统频率恢复，大幅度提升系统的动态响应能力，实现风氢耦合系统稳定运行。
