Abstract

Abstract: Secondary microgrid voltage control is one of the most important parts of hierarchical control in islanded mode. By using of fuzzy and adaptive control methods, this paper presents a new method for secondary voltage control of islanded microgrid and also uses the rules of the backstepping method to obtain a control signal. The backstepping method has been used as a robust control technique to overcome the uncertainty and the effects of nonlinear terms, and the fuzzy method has been used to reduce its complexity. The adaptive method also gives fuzzy approximation coefficients. Considering the effect of neighbor agents on each other as uncertainty, a robust decentralized control method has been implemented in islanded microgrid. The simulation results in MATLAB environment show the controller's ability to eliminate voltage deviations and the appropriate dynamic response.
