Subtransmission Reduction for FAGTS Site Selection in Large Power System

대규모 전력계통에서의 하위 송전계통 축약을 이용한 FACTS 위치선정 연구

This Paper Proposes the FACTS site selection method using subtransmission system reduction. A general method which uses the sensitivity of the variation in voltage and reactive Power has been used to determine the location of shunt type FACTS device, but there is a difficulty to find a proper location due to the overestimation of the effect of sub-transmission systems. Therefore, there is a need to reduce sub-transmission system for finding an effective location of shunt type FACTS devices such as SVC(Static Var Compensator), STATCOM(Static Synchronous Compesator), and so on.
