Abstract
Optimal Power flow (OPF) is crucial in a power system, and this is essential for continuous monitoring of the system’s current status, system stability, extension of the system, best operation of the system, etc. This paper applies Particle Swarm Optimization (PSO) and proposed Opposition-based Modified Rao’s (OMR) algorithms for OPF solutions with various technical constraints. In this paper, the objectives are to minimize the total generation cost, total real power loss, sum of squared voltage stability index, and total voltage deviation and to know performance parameters in terms of real and reactive power flows, voltage profile, load bus voltage deviations, load angle and voltage stability indices. To see the effectiveness of the proposed OMR algorithm, IEEE standard 30-bus system is considered and tested. The results obtained with the proposed OMR algorithm are better than the other techniques in the literature.
