A combination between FACTS devices for a safe and an economic power system operation

摘要

Owing to the rising need for power electronics for sustaining the high quality of electrical energy and the considerable cost of such a technology, we present in this paper a solution dealing with these problems. We propose to create a combination between SVC (Static VAR Compensator) and TCSC (Thyristor Controlled Series Compensator) to reach the performances of UPFC (Unified Power Flow Controller) in improving system stability. This combination guarantees both: economic investment and efficient functioning. The investigation of the proposed idea and the comparative studies are performed in the IEEE 14-Bus system under EUROSTAG environment.
