Description
Summary:This paper presents the design of a robust proportional–integral–derivative controller for grid voltage control of an islanded microgrid. The microgrid consists of several distributed generation units and local loads. The loads are parametrically unknown and uncertain which ensure the variation of microgrid performance. The controller is designed to achieve fast transient response, zero steady-state error and robust performance in the presence of un-modeled loads, dynamic loads, nonlinear loads and harmonic loads. The performance of the controller is tested using MATLAB/Simulink SimPowerSystems. The simulation results show that the proposed controller is robust and provides high performance for voltage control of the islanded microgrid system by achieving the rise time, peak time, percentage of OS, and settling time of 0.00492, 0.018, 2.19, and 0.0271 ms.
