This paper presents the modeling of nonlinear load used in domestic and small scale industrial distribution system. Proportional integral controller is used for the current control, fuzzy based MPPT is used for the variation of power from PV due to the change in atmospheric condition. Harmonics are compensated by the virtual impedance implementation. However due to increasing implementation of multiple distributed generation in residential areas, DG grid interfaced converters are used to improve the power quality. Harmonic analysis of the distribution system is used to study the behavior of equipment connected in the non–sinusoidal system environment for designing and optimal location of filters. THD is used as harmonics index to study the effect of these nonlinear loads at utility. In depth analysis and comparison of different compensation schemes based on the virtual harmonic damping impedance concept are carried out. The effect of harmonics and the compensations are verified by the analysis and simulation by MATLAB/Simuink
