Abstract

Power system distribution losses and bus voltage magnitude deviations are critical issues that require attention in improving electricity supply to the consumers. It is a global concern, however this study is conducted in Okwuzi town 11kV power system consisting of one power transformer and seven (7) distribution transformers with a total demand of 2.8MW, High power losses and less voltage stability issues are some challenging problem in the town. Load flow analysis of the 11KV distribution network using embedded Newton Raphson method in Electrical Transient Analysis Program (ETAP) software and utilizes to analyze the system with the application of Particle Swarm Optimization (PSO) algorithm to find the KVAR size and location of Static Synchronous Compensator (STATCOM) for reducing power losses and improve the voltage profile, From the evaluation, the critical bus recorded is bus 9 with optimal size of about 2500KVAr. A load flow analysis revealed that the active power loss and reactive power loss in the existing network is 85.63kW and 193.7167KVAr respectively. With the integration of STATCOM, active power loss and reactive power loss reduced significantly to the values of 67.03kW and 143.71KVAr. The result also revealed that when STATCOM was penetrated into the network, all the bus voltage magnitude falls within IEEE statutory limit, hence electric power supply to the study area has improved.
