Abstract

Abstract:
The problem of reactive power dispatch (RPD) is to allocate reactive power generation
so as to minimize the real power transmission losses and keep all voltage within the
limits, while satisfying a number of equality and inequality constraints. This paper
presents a new methodology for solving RPD. This methodology is consists of two
phases. The first one employs the genetic algorithm (GA) to obtain a feasible solution
subject to desired load convergence, while the other phase employs efficient GA to
obtain the optimal solution. Also, some major improvements are added to the traditional
genetic algorithm in order to improve the convergence and to find a better solution.
Extensive testing of the proposed algorithm is done on standard IEEE-30 bus system
and the results have been compared to those reported in the literature. The comparison
demonstrates the superiority of the proposed approach and confirms its potential to
solve the RPD problem.
