UPFC model for power flow using IPLAN

IPLAN을 이용한 UPFC 조류계산 모형

This paper presents an approach that provides an equivalent initial operating condition of UPFC in load-flow study for stability analysis. The UPFC model for load-flow implemented by IPLAN in PSS/E is represented by an equivalent load injection. In doing so, the transmission line to which UPFC is connected is disconnected and the function of UPFC is represented by the equivalent load variation. This operating condition may not be adequate as an initial condition for subsequent dynamic simulation. The proposed approach provides a way of equivalencing UPFC load injection without line disconnection. The method was applied to a realistic power system for validity.
