In deregulated electric power systems, one of the most important topics is to augment the total
system social welfare. Many different methods have been carried out for this problem. One of the most viable
methods to increasing system social welfare is to supply the reactive demands as locally. In this way, the
reactive demands are supplied via locally reactive sources and the capacity of transmission lines is not used to
transfer reactive power of demands. Thus, the congestion of lines is not reached and the system social welfare
which is related to the congestion of lines is increased. In this scope, this study addresses an optimal Reactive
Power Planning (RPP) in a deregulated power system. The proposed method optimizes two objective functions
at the same time within one general objective. The optimized objectives are minimization of total investment
in reactive power support and maximizing of total system social welfare. Genetic Algorithm (GA) is used to
solve the optimization problem. The validity of the proposed method is verified on a typical power system.
