主 题:Fixed-time distributed secondary control super-twisting algorithm integral sliding mode external disturbances
摘 要:This article primarily examines the fixed-time secondary voltage and frequency control of islanded microgrids with external disturbances. First, a distributed observer is introduced to ensure that each distributed generator (DG) can accurately estimate the reference voltage level. Subsequently, a distributed integral sliding mode is constructed through the super-twisting algorithm, and the continuous super-twisting part is used to compensate for the disturbances and eliminate chattering phenomena. Furthermore, a distributed secondary control strategy is designed using the backstepping method, which can achieve fixed-time regulation of voltage and frequency in a microgrid with unknown parameters. Finally, the validity of the method is proved in MATLAB $ {\circledR } $ (R)/SimPowerSystems.
