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.

Wind farms are integrated with the power grid system to provide active and reactive power.Because in a wind farm,wind turbines(WTs)are highly coupled to their operating conditions,a central wind farm supervisory unit must take into account these conditions when producing power control references for each WT.The aim of this paper is to man-age and control the active and reactive power of wind farms based on squirrel cage induction generators and back-to-back converters.The proportional distribution algorithm is used for distributing wind farm power to individual WTs.In addition,we consider the development of a local power management and control units for WTs.This is in order to extract the maximum available power from the wind,and to provide the active and reactive power predetermined by the transmission system operator,or to satisfy the grid code requirements considering Low Voltage Ride-through capability.The power dispatch strategy is to be used on all WTs using the distribution algorithm while ensuring the control loops using the proposed Active Disturbance Rejection Control strategy.The results demonstrate that the proposed strategies are efficient and can guarantee the safe integration of wind farms into the grid while respecting grid code requirements and power system stability.
