Enhancement of Power Quality with a Wind-Integrated Shunt Active Power Filter

This work presents grid-tied wind power generating system (WPGS) with a shunt active power filter (SAPF) is put forward for compensation of reactive power, balancing of grid current, correction of power factor and reduction current harmonics. Perturbation and observation (P&O) based MPPT is implemented to control the boost converter and achieve the maximum power from the WEGS. The proposed controller is used to send the maximum power from the renewable energy system to the critical loads with unity power factor. The proposed controller is implemented using MATLAB/Simulink platform under several test conditions such as balanced grid voltages, grid voltage sag & swell and dynamic load condition. Finally, the suggested control scheme’s dynamic performance is determined to be good, and the THD analysis of grid currents is found to be well within IEEE 519 limits.
