Abstract

Reactive Power Dispatch (RPD) and voltage control of power systems is one of the important tasks in the operation and control of the power system. RPD problem can be formulated as a non-linear constrained optimization problem. This paper presents a Genetic Algorithm (GA) approach for solving the reactive power dispatch problem including the line flow constraint. Minimization of voltage Instability with FACTS and without FACTS devices is the objective of this reactive power optimization problem. The proposed algorithm has been applied to find the optimal reactive power control variables in IEEE 30 system in which the control of bus voltages, tap position of transformers and reactive power sources are involved to minimize the transmission loss in addition to improving the sum of square of load bus voltage stability indices. The simulation results are promising and show the effectiveness of the proposed RPD approach in the presence of FACTS device.

Keywords
