Abstract

With the increasing demand of electric power, transmission congestion becomes a popular phenomenon in power systems. In order to improve the ATC (Available Transfer Capability) between buses of the network, this paper proposes a location method of TCSC in power grid. Power transfer distribution factor and line outage distribution factor are used to build the mathematical model of ATC considering the N-1 security constraints. Meanwhile, the genetic algorithm is used to calculate the location and the capacity of TCSC. The proposed method is applied to the IEEE 14-bus system. The results show that this method can improve the ATC of power systems with TCSC obviously.
