Abstract

In this paper, islanded operation of a microgrid system under load uncertainties is considered using a robust control strategy. This system includes two Distributed  Generation (DG) units that are connected to the local load  using inverter and LC filters. The main objective is regulating the load voltage in the presence of large perturbations in the local load. To achieve the objective, a LMI-based mixed H2/H state-feedback control technique with regional pole placement is utilized for each DG. Fast tracking, zero steady-state error, and robust performance in presence of uncertainties are some
of the achievements of the proposed technique. The effectiveness of the proposed method is illustrated in different
operating conditions using MATLAB/SimPower System. A PWM inverter block from SimPower System toolbox is used in
all simulations to implement a realistic nonlinear model of each DG.
