enhancing power quality in distribution networks integrated with distributed generation sources using mopso and soft open points (sops)

This paper introduces a novel approach to improving voltage profiles in a 22-bus radial distribution network by integrating distributed generation (dg) sources with advanced optimization techniques. by leveraging multi-objective particle swarm optimization (mopso) alongside soft open points (sop) devices, this study effectively reduces power losses, total harmonic distortion (thd), and voltage imbalance. the proposed method not only optimizes the allocation and sizing of dg units but also strategically deploys sop devices to enhance operational flexibility. simulation results conducted in matlab environment demonstrate that the integration of sops significantly improves the overall voltage profile, minimizes active power losses, and substantially reduces thd levels across the network. furthermore, the coordinated optimization approach enhances the resilience and stability of the distribution system under varying load conditions. the improvement in power quality indices, including voltage regulation and harmonic performance, highlights the practical viability and technical effectiveness of combining mopso optimization techniques with sop deployment for resilient and efficient distribution network management.
