Optimal Allocation of TCSC Using Heuristic Optimization Technique

With the massive increase in the population and, as a result of the expansion of the power grid, new problems such as loss power in network retaliation were created. So studies on this issue began. These studies led to the emergence of FACTs devices. The Flexible AC transmission System (FACTS) devices, such as, thyristor controlled series compensators (TCSC) may be used to enhance system performance by controlling the power flows in the network. Optimal location and setting of this devices are considered complicated and multi-objective problems. It is important to limit the number of TCSCs and to locate optimally these devices in the power system because of their considerable costs. In this paper, efficient heuristic optimization technique, is employed to find the optimal location and setting of a thyristor controlled series capacitor (TCSC) device in a modified system. To demonstrate the effectiveness of the proposed approach, IEEE 30-bus test system has been studied.
