Abstract A thorough study is presented here that investigates the complicated protection concerns that develop when solar photovoltaic (PV) systems are linked to existing power grids. The report also gives specific mitigation measures that may be used to overcome these issues. The integration of solar photovoltaic (PV) systems presents a number of issues that are not found in other systems, including defect detection, power quality management, system stability maintenance, and protection coordination. The purpose of this paper is to provide power system engineers, researchers, and utility operators with practical solutions to ensure the reliable and safe operation of grid-connected photovoltaic (PV) systems. These solutions are provided through a rigorous analysis of current research along with industry practices.
