PHOTOVOLTAIC BASED SHUNT ACTIVE POWER FILTER USING P-Q THEORY FOR ENHANCING THE POWER QUALITY

Abstract

This paperproposes three phase shunt active powerfilter with photovoltaic array and battery, incorporatedwith DC—DC boost converter. Thefilter consists of three phase voltage source PWconverter with DC capacitor atthe input side. It provides source harmonic reduction with reactive power compensation for loads. The PV array isconnected to VSC (Voltage Source Converter) with the help of boost converter in order to maintain the load. Theinstantaneous p-q theory based control algorithm is proposedfor the shunt active powerfilter. In this algorithm, the PIcontroller is used to regulate the DC link capacitor voltage of the converter with respect to the reference value and thereference current calculation is done according to it. The hysteresis PW current controller gives the switching to theconverter. The eflectiveness ofthe proposed system is verified by using the IllATLAB/Simulink software.
