Abstract

Restructuring in electric power system has led to major usage of the transmission system and to make new transmission lines it is very difficult and impossible. In this situation, it is necessary for the system operators to control power flows in lines so that the existing transmission network can be operated in the most safe state. However, power system restructuring is found to be associated with a concept called transmission congestion. Therefore it is necessary to solve this issue. This paper looks for relieving line congestion by using fuzzy technique or method to determine the optimal location of series FACTS device like thyristor controlled series capacitor (TCSC) in a 5-bus system.
