基于VSG的风光储氢系统并网逆变器自适应调频策略
An adaptive frequency regulation strategy for grid-connected inverter in wind-solar-hydrogen storage system based on virtual synchronous generator
摘要
Abstract
To address the issue of power-frequency fluctuations in a wind-solar-hydrogen storage grid-connected sys-tem under varying operating conditions when using traditional virtual synchronous generator(VSG)control strate-gies,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)charac-teristics 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 al-gorithm 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 elec-trolyzer are reduced,the recovery speed is accelerated,and the system stability is enhanced.关键词
