Grid integrated PMSG based Wind Energy System: Modelling, control and simulation
Solar, Wind, PV, MT are commercially available Distributed generation system for long time but suffers from grid integration issues. In case of Wind Energy System (WES) power quality is challenging issue for grid connected system. Further there are challenges associated with extract of maximum power and reliability of supply. To address the subject concerns, optimum power evacuation and reactive power compensation solution has been proposed in the paper. This paper presents grid connected WES with source side control and grid side converter control. It further contains comparison between grid side conventional controller and TS fuzzy controller along with design of LCL filter. Control of the inverter has been done by Synchronous reference frame (SRF) scheme. The objective behind the grid side converter control is to evacuate the active power and reactive power from WSES. In case load requirement exceeds wind energy generation, the control architecture will ensure that remaining demand will meet through grid supply. Reactive power compensation of the load is done through the control algorithm. Working of proposed system is investigated under nonlinear, unbalance, varying load and with change in wind speed. Grid code compliances were considered to verify the effectiveness of proposed system. Simulation is performed using MATLAB/Simulink platform.
