摘要
The purpose of this paper is to propose an efficient model and a robust control that ensures good power quality for the AC microgrid(MG)connected to the utility grid with the integration of an electric vehicle(EV).The MG consists of two renewable energy sources:a photovoltaic system(PVS)and a wind turbine system(WTS)based on a permanent magnet synchronous generator(PMSG),with the integration of an EV.These sources are used to supply active and reactive power to the AC bus and the utility grid.Maximum power point tracking(MPPT)based on the perturb-and-observe(PO)method is used to increase the efficiency of the photovoltaic modules and improve overall performance.The MG system includes a 2-MW WTS,a 100-kW PVS and 12 kW provided by the EV.To validate the performance of the proposed system,a series of simulations were conducted using the MATLAB/Simulink?environment.The results demonstrate that the proposed system ensures high performance in terms of power quality,system stability,power tracking and safe integration of the EV.
