中文摘要:

针对风光储氢并网系统采用传统虚拟同步发电机（virtual synchronous generator, VSG）控制策略在工况改变时的功频波动问题，提出一种VSG参数自适应控制策略。文中搭建风光储氢并网模型，通过VSG技术使系统具备惯量和一次调频特性，并建立VSG有功小信号模型，分析参数变化对系统稳定性的影响规律，通过系统受扰时的角频率偏差和角频率变化率振荡曲线，分析惯量阻尼的动态特性，设计一种高精度的模糊算法，实现参数的非线性调整，并给出参数取值范围，在Matlab/Simulink平台中搭建仿真模型进行验证。结果表明，在有功参考指令变化和本地负载突变工况下，采用VSG参数模糊自适应控制后，系统的功频响应均得到了改善，直流母线电压和电解槽的波动减小，恢复速度加快，有利于系统的稳定运行。

英文摘要:

To address the issue of power-frequency fluctuations in a wind-solar-hydrogen storage grid-connected system under varying operating conditions when using traditional virtual synchronous generator (VSG) control strategies, an adaptive VSG parameter control strategy is proposed. A grid-connected model of the wind-solar-hydrogen storage system is constructed. The system is equipped with inertia and primary frequency modulation (FM) characteristics through VSG technology, and an active small-signal model of the VSG is established to analyze the impact of parameter variations on the system. The dynamic characteristics of inertia damping are analyzed using oscillation curves of angular frequency deviation and its rate of change during system disturbances. A high-precision fuzzy algorithm is designed to achieve nonlinear parameter adjustment, and the range of parameter values is determined. A simulation model is built on the Matlab/Simulink platform for verification. The results show that under conditions of active power reference command variations and local load mutations, the power-frequency response of the system is improved after applying the fuzzy adaptive control of VSG parameters. The fluctuations in DC bus voltage and electrolyzer are reduced, the recovery speed is accelerated, and the system stability is enhanced.
