Reactive power control is a nonlinear and non-convex optimization problem which has a salient effect on the secure and economic operation of the power system. In this optimization problem the proper settings of bus voltages, tap settings of transformers, and reactive compensation devices. The optimization problem can be solved considering different objects such as decreasing power loss of the system, increasing voltage stability and also decreasing voltage deviation of buses. In this work a compromising multi-objective approach has been used to solve the reactive power control problem. Also for solving the optimization problem the global best harmony search algorithm has been used. The IEEE_57 bus system has been used in this study. The results are compared with other optimization algorithms and the results show that the selected approach is effective and approaches feasible results.
