Active and Reactive power optimization is a challenge in which both integer and non-linear programming are involved. Meta heuristics approaches have been shown to be effective in finding the best solutions. The purpose of this study is to examine the use of Particle Swarm Optimization (PSO) inside the MATLAB environment for the purpose of improving reactive power compensation techniques in the ever-changing landscape of the electrical sector, with a specific emphasis on Distributed Energy Resources (DER). This work highlights the inherent significance of reactive power in terms of controlling voltage, enhancing power factor, and reducing system losses. PSO is considered a feasible optimization approach for reactive power dispatch because the study goes into detail on reactive power compensation complexities such as load compensation and voltage support. The research also looks at how distributed generator (DG) allocation affects the performance of the system in general, as well as providing specific details on the necessary hardware and software for efficient substation operation that guarantees both reliability and accuracy. The results reveals that incorporation of DGs into the system along with optimal placement based on the PSO technique has presented viable responses, such as reducing power losses for active and reactive power, respectively, with the addition of three DG units into the network under consideration. This translates into increased energy efficiency and voltage management within the distribution system. Lastly, this paper contributes not only to theoretical advances in power engineering but also has practical implications for sustainable energy systems that are available today. It can also influence the subsequent path of reactive power compensation techniques in the electrical industry.
