Shunt active filter using five level CHB multilevel inverter for mitigation of harmonics from solar photovoltaic system

Supply utilities and consumers are now a days more concerned about the adverse effects of grid connected solar photovoltaics. We must reduce harmonic emission injection to the grid. In this paper solar power system model is designed by using MATLAB/Simulink with five level cascaded H-Bridge shunt active harmonic filter using P&O based MPPT algorithm. We have successfully reduced total current harmonic distortion within acceptable limit as per IEEE 519-1992 standard.
