Reactive power optimization of Port Harcourt Electricity Distribution (PHED) using an emerging Rao-1 type optimization was carried out in this research work. The study considered the minimization of real and reactive power fitness error mismatches in the absence and the presence of shunt compensation for a 4-bus network of 33/11-kV feeders located at the Diobu zone. Simulations were carried out using the MATLAB programming language and a comparison was made between the Rao-1 approach and the Particle Swarm Optimizer (PSO) based on fitness response and computational run time. The simulation results showed a competitive performance of the Rao-1 type optimizer with a mean fitness error of 0.0023 and 0.0038 for uncompensated and compensated cases. Also, the Rao-1 type optimizer run time exhibited a faster rate than the PSO for uncompensated and compensated cases. As a result, the Rao-1 type optimizer was recommended as a promising approach for reactive power minimization in a distribution power network, particularly for critical simulation work.
