Impact of wind farm and thyristor-switched series capacitors in voltage, active and reactive power in normal condition of network

Abstract

This paper aims are improving voltage profile and reducing the losses of active and reactive powers. For simulation purposes, the standard IEEE 14 buses network has been used. Response of the wind turbines in this network should be noted while losing the power network. With regard to the improvement of the voltage profile and reduction of the losses in critical buses, the reactive power resources, i.e. thyristor-switched series capacitors, are used on the mentioned circumstances. In this study, the required amount of wind turbines and thyristor-switched capacitors are placed, then the different conditions are individually and simultaneously considered using genetic algorithms with/without the wind turbines and thyristor-switched series capacitors in normal situation of the network. The results indicate that using thyristor-switched capacitors together with the wind farm can provide enough active and reactive power for the network which leads to an increase on the network capacity and a decrease on its losses using genetic algorithms.
