摘要

This paper presents a robust and effective method for voltage and current control of an islanded microgrid. The effects of external disturbances and parametric uncertainties pose challenges in voltage and current control of islanded microgrids. Therefore, adopting a robust and stable control method is imperative. Nonsingular terminal sliding mode controller (NTSMC) which is a subset of sliding mode controllers (SMC) is proposed in this paper to control the voltage. Moreover, NTSMC is robust against a wide variety of uncertainties and external disturbances. Unlike conventional SMC, NTSMC ensures finite time convergence to the equilibrium point. The proposed control method was implemented in Matlab/Simulink, and its performance was evaluated under different loads and parametric uncertainties in the presence of external disturbances. Simulation results show the desirable performance of the proposed controller in maintaining stability of the islanded microgrid with precise voltage and current control against significant uncertainties and external disturbances.
