Abstract: For planning and proper operation of power system, optimization of reactive power is a must. The reactive power cost minimization aims at dispatching the reactive power in such a way that maximum real power is dispatched and minimum reactive power is utilized so that voltage is maintained at required level. The work presented in this paper discusses various loading conditions and the improvement after applying the optimization technique. It compares the reactive power cost both before and after optimally dispatching the reactive power and thereby ensuring the voltage stability of the power system. Optimal power dispatch is solved using Time Varying Acceleration Coefficient and Particle Swarm Optimization. Reactive support of the generators has two functions such as voltage control and real power delivery. It explains how the application of PSO helps in reactive power control and reduction in power losses.
