Reactive compensation in transmission electrical grids based on non-linear programming considering optimal SVC location

Abstract

Electrical transmission lines is one of the most important stage in electrical power systems, because it is responsible for carrying electrical energy from the generation to the sub-transmission stage and subsequently to be distributed. The applications of the SVC FACTS on the bars of the electric power system are varied; these devices allow us to modify the power flow in power system, in order to maximize the capacity of the transmission lines; locating these reactive power compensating elements has a high cost, so it is necessary to locate them optimally and intelligently, in order to make the investment feasible. In the present research, a methodology to minimize the deviation of the magnitudes of the voltage profiles is presented, for which we analyze the behavior before and after the reactive compensation by means of the optimal parameters of AC power in the IEEE 14 and 30 buses model. Finally, the location of reactive power compensators in buses of electrical power system improve the voltage profiles in each of its bus, minimizes investment costs and reduce the power losses in transmission lines.
