Abstract

This paper presents a comprehensive review of harmonics dominance in PV integrated network. The findings of the review conducted for different scenarios are further supported by the results of an experimental case study exploring the dominance of harmonics in a real time PV integrated microgridunder varying solar irradiance condition. It is concluded that the level of Total Harmonic Distortions (THD) in the power system network varies in different scenarios. Some of the important scenarios are: (i) percentage of PV penetration in distribution network with respect to the types of connected load, (ii) location of PV integration, (iii) effect of harmonic resonance in power network, and (iv) varying power output of PV inverters with varying solar irradiance. A harmonic management system is finally proposed to limit the excessive harmonics in the network under different network conditions. The proposed harmonic management can be used to maintain the THD level within the standard limit and ensures the quality of energy supply to the communities.
