卡尔曼滤波改进虚拟同步机控制研究
Research on VSG control improved by Kalman filter
摘要
Abstract
The virtual synchronous generator(VSG)can provide inertial support for the power grid by simulating the dynamic characteristics of the synchronous generator.However,the noise in the communication transmission process of the VSG system will affect the accuracy and cause frequency jitter.Therefore,the Kalman filter is added to the traditional VSG control system to form a new disturbance immunity control mode.The covariance matrix Q and R of Kalman filter are used as the individual code of genetic algorithm,and the fitness function is designed to evaluate the filtering effect under different parameter combinations to improve the performance of VSG system.The simulation results show that the proposed control strategy can effectively improve the running stability and eliminate the frequency jitter at the machine end.关键词
