Distribution system reconfiguration for power loss minimization and voltage profile improvement using Modified particle swarm optimization

Distribution companies (DSCOs) are trying to reduce the high real loss and manage the poor voltage profile, so power loss minimization and voltage profile improvement are the main and important tasks to be faced by electrical engineers in the distribution system (DS). To achieve this goal, distribution system reconfiguration (DSR) is one of the greatest keys and vital analysis to reduce power loss and enhance system voltage profile. In this paper, Modified particle swarm optimization (MPSO) is used for solving the DSR with the objective of minimizing real power loss in the presence of a regular of some constraints. To prove the applicability of the proposed method, MPSO has been applied on operated example the standard IEEE 33-bus system and the results compared with the other popular algorithms. It observed from the numerical results of the test that the real power loss is reduced by 31%, the average system voltage enhanced by 2% and 2.5% improves the minimum voltage.
