State of Art for Power Quality Issues in PV Grid Connected System

In the midst of increased demand of energy and depleting resources, the world is moving towards the renewable sources of energy. Out of all available renewable resources, solar proves to be the best energy source; due to its various advantages over other renewable energy sources. The Photovoltaic (PV) system when connected with the grid proves to be a boon to the modern society. Although various power quality issues arises while integrating large PV system with grid. Poor or Low power quality could lead towards financial falls and disturbance to end users. Also due to low power quality issue, the power system components get overheated and start functioning in unwanted regions; causing great damages. This paper reviews the issues of electrical power quality allied with the Grid associated photovoltaic system.
