In many industrialized countries, power electronic technologies have become integral to the electrical system at all levels, driven by the growing emphasis on energy efficiency and conservation. To meet the increasing energy demands of modern industry and daily life, researchers have explored alternative energy sources over the past decade. Among these, solar energy has emerged as a particularly promising resource due to its abundance and environmentally friendly nature. Photovoltaic (PV) cells convert sunlight into direct current (DC) electricity, and power converters are used to efficiently integrate this energy into the electrical grid. While solar PV systems help meet distribution system demands, they can also introduce power quality issues that need to be addressed. In recent years, the widespread integration of renewable energy sources and modern power electronics into the grid has led to a higher presence of nonlinear loads. These loads can inject harmonics into the system, affecting overall grid stability. This research focuses on addressing such power quality challenges to ensure reliable and efficient integration of solar energy into the utility grid.
