Suppression Strategy of DC Bus Voltage Fluctuation in Hybrid Microgrid Based on Fuzzy Decoupling Linear Auto Disturbance Rejection Control
摘要
Abstract
A decoupling linear auto disturbance rejection control strategy is proposed to address the phenomenon of voltage fluctua-tions in the DC bus of hybrid microgrids caused by factors such as sudden load changes,disturbance addition,and system grid connec-tion.Firstly,a mathematical model of the hybrid microgrid converter is established based on the circuit structure of the hybrid microgrid.Then,in order to improve the system's anti-interference ability,decoupling treatment is performed on the linear self disturbance rejection to form a decoupling type linear self disturbance rejection.Furthermore,in order to achieve real-time parameter optimization,a fuzzy adaptive optimization algorithm is introduced to form a fuzzy decoupling auto disturbance rejection control strategy.Finally,a physical and digital model of the hybrid microgrid is established and simulation and semi physical simulation experiments are conducted.The results show that the fuzzy decoupling active disturbance rejection control strategy has excellent abil-ity to suppress DC bus voltage fluctuations.关键词
