Abstract


A method of distribution network reconfiguration using Particle Swarm Optimization (PSO) for active power loss minimization and reliability improvement is proposed in this paper. The PSO based reconfiguration algorithm is used to determine the optimum positions of the tie and sectionalizing switches of the network leading to power loss minimization and increase in reliability. The proposed method was applied to the IEEE 33 test bus system. Thereafter, the method was applied to the 11kV Pama distribution feeder in Ungwan Boro Injection sub-station located in the southern part of Kaduna State, Nigeria. For the standard IEEE 33 test bus system, the proposed method produced a power loss reduction of 49.12 %. The system average interruption frequency index (SAIFI) increased by 5.69%. The optimal location of the tie switches were found to be positions (4-5), (11-12), (16-17), (19-20), and (21-22). A power loss reduction of 57.15% was achieved for the 11kV Pama distribution feeder, a case study. SAIFI increased by 25.19% while the optimal location of tie switches were found to be positions (6-7), (14-15) and (17-20) for the 11kV Pama distribution feeder.
