POWER LOSS REDUCTION IN DISTRIBUTION SYSTEMS USING AUTONOMOUS GROUP PARTICLE SWARM OPTIMIZATION (AGPSO) ALGORITHM

Abstract: In the stream of study of power systems, the radial distribution system is considered to be one of the most popular types of distribution systems. Loss minimization, maintenance of good voltage profile is the main objectives of radial distribution system. Autonomous Group Particle Swarm Optimization (AGPSO) is recently employed to achieve the above mentioned objectives. In this algorithm reconfiguration and DG placement were studied, while implementing on a 33-bus radial distribution system at three different load levels and the results were tested. Earlier, Harmony Search Algorithm was employed to achieve the above mentioned objectives, but AGPSO gives better results in comparison. The test results prove that AGPSO algorithm is more efficient, therefore suitable for loss minimization and maintenance of good voltage profile.
