The Analysis Harmonic for Connect Grid Photovoltaic Rooftop Synergy Distribution System

This paper presents the harmonic analysis for connecting grid photovoltaic rooftop synergy distribution system. The harmonic of photovoltaic rooftop affects the power distribution system’s power quality. Under limitations, it has technical impacts such as unbalanced current, flicker, and load in the photovoltaic rooftop system. Therefore, this paper is presented to analyze the harmonics problem in the power distribution system from the photovoltaic rooftop by measuring unbalanced current, flicker, and harmonic photovoltaic rooftop synergy distribution system. The results showed that measurement points at the point of common coupling (PCC) between photovoltaic rooftop and distribution system could analyze the distribution system’s harmonics.
