Enhancing the contingency performance of HELENSÄHKÖVERKKO OY 110 KV NETWORK by optimal installation of UPFC based on Genetics Algorithm

Unified Power Flow Controller (UPFC) has a promising effect on controlling the characteristics of the power system operation. During the contingency outage cases, the transmission lines are overloaded and the buses are subjected to voltage violations. Unified Power Flow Controller (UPFC) has both shunt and series controller effect inside its frame. This option gives the UPFC the power to control the voltage profile and the transmission lines flow simultaneously. In this paper, we use the Genetics Algorithm (GA) to find the optimal location and the optimal settings of UPFC to improve the performance of the power system at the contingency of the transmission line outage. The proposed technique will be tested on the IEEE 6-bus system to show the validity of the technique. This procedure is proposed for being applied on the Finnish network, Helsinki HELENSÄHKÖVERKKO OY 110 KV NETWORK. The simulations will be achieved until operating conditions of Year 2020.
