Abstract

The global warming concerns, diminishing fossil fuels have made it necessary to move towards Renewable Energy Sources (RES) as a future energy solution. As a result of this, Renewable energy resources (RES) connected with distribution systems increases gradually. This paper presents a narrative control strategy for the implementation of a three-phase four wire current-controlled Voltage Source Inverter (CC-VSI) as both power quality improvement and wind energy extraction. For power quality improvement, the inverter works as a shunt active power filter. The output of wind energy source is a DC voltage that determines the DC-bus voltage and the dc-side voltage is controlled by a fuzzy PI controller. The new approach has been illustrated in order to find the best way to reduce network harmonic currents of the connected load. All of the studies have been carried out through dynamic simulation using the MATLAB/Simulink Power System Toolbox.
