Analysis reveals THD reduction in a PV integrated grid connected system, suggesting the efficacy of passive LC filters.
The present work deals with the reduction of harmonics which is produced by non-linear loads when connected with PV integrated grid connected system. Two PV sources are considered and they are synchronized with grid where inverter control for a one PV is given with the use of PLL technique and another PV inverter control is not a PLL dependent. Two PVs grid integrated system is then tested by connecting linear and non-linear load. The harmonics created by non-linear load is reduced by using passive LC filter. The model is executed in simulation and the THD content is determined by FFT analysis in MATLAB/SIMULINK.
