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.
