Waveform Driven Event Mitigation of PV System using Active Filtering for Controlled Converter Load

In Proposed architecture proportional integral based power quality enhancement PV generation system is designed for current harmonics mitigation, improve power factor and compensate reactive power for three-phase three-wire system. Structure consists of SVPWM based three phase inverter supplied with standalone photovoltaic system, self-supported DC bus, shunt active power filter controlled with proportional integral controller and non-linear load. Boost converter incorporated with perturb and observe maximum power point tracking technique is used to acquire maximum output from photovoltaic array. Power quality issue waveform driven event harmonic is caused due to non-linear load (NLL). Implemented system can effectively mitigate the current harmonics and improve power quality. Total harmonic distortion of the source current is obtained below IEEE-519 standards. We can see effectiveness of developed system from simulation results obtained from simulation modelling in 2015(b).
