Abstract

For the secondary voltage control model based on inverter of isolated island microgrid (MG) theory, a fault-tolerant controller is designed under the influence of external interference. The observer is used to reconstruct fault information and estimate interference in real time. Then, based on the observer signal, a controller based on the backstep method is established to realize fault tolerance and interference compensation, and ensure that the output voltage amplitude of the distributed power generation system stably tracks the given track. Simulation results verify the effectiveness of the proposed scheme.
