基于模糊控制的虚拟同步电机惯量和阻尼控制策略
Fuzzy Control-Based Virtual Synchronous Generator Inertia and Damping Control Strategy
摘要
Abstract
In view of the problem of the decline in the transient stability of microgrids caused by the increase in the proportion of new energy grid connection,a VSG(Virtual Synchronous Generator)inertia and damping control strategy based on fuzzy control is proposed.The proposed strategy fully exploits the advantages of fuzzy control in non-linear processing.Based on the power-angle characteristic curve of synchronous motors and the derivation of inertia and damping adjustment principles through VSG transient behavior analysis,a more comprehensive and detailed fuzzy control rule has been redesigned.This rule adjusts the moment of inertia and damping of VSG in real time based on the frequency deviation and its rate of change,achieving precise and real-time control of VSG parameters.The exper-imental results show that,compared with the fixed parameter and traditional adaptive VSG control methods,the pro-posed strategy significantly improves the anti-interference ability of VSG under different interference conditions,ac-celerates the response speed,and effectively enhances the transient stability of the microgrid.关键词
