Abstract
The integration of renewable energy sources, particularly solar power, into existing electrical grids is critical for developing a reliable and efficient power system. This study analyzes power flow in Peshazi substation in sulaimani city which feeds a distribution network by about a 60 MW and optimizes the placement of solar sources. The analysis is based on data from Directorate of electricity distribution of Sulaimani city that encompassing 15 distribution feeders with varying loads, power generation, and line lengths, aiming to enhance efficiency, stability, and reliability. The integration of solar energy, driven by its decreasing costs and abundant availability, poses unique challenges due to its variability. The paper outlines methodologies for optimal placement and sizing of solar PV systems to address these challenges study the power system simulation for Engineering (PSSE) software is utilized to simulate and evaluate the integration the solar source to existing grid. Key findings demonstrate significant voltage drops and power losses in certain distribution feeders, emphasizing the need for strategic solar PV installation to improve voltage stability and reduce transmission losses.
