The Current State of the Art for PV Grid Connected System Issues with Power Quality

The globe is turning to renewable energy sources in the face of rising energy demand and diminishing. Solar energy is the best renewable energy source currently accessible because of its many benefits over other renewable energy sources. Presented is a study on the evaluation of solar energy's integration issues into electrical grids with power quality issues By using the sun's energy and converting it from DC to AC, photovoltaic or PV systems are driving this transformation. Due to the present energy demand, the depletion of fossil fuel sources, and environmental effects, integrating renewable energy from this source into grids has gained attention among researchers and scientists. In this study, the power quality issues due to solar-grid integration are highlighted, the properties of the solar system that make them suitable for integration, and the consequences and difficulties of integration are covered. When connected to the grid, the photovoltaic (PV) system proved to be beneficial for contemporary civilization. Although connecting a sizable PV system with the grid raises a number of power quality challenges. Poor or low power quality could result in losses in revenue and inconvenience for end users. The components of the power system overheat and begin acting in undesirable places as a result of low power quality issues, which results in significant damage. This paper examines the problems with electrical power quality related to grid-connected solar systems.
