Unified power flow controller (UPFC) [1,2] can be used for power flow control, loop-flow control, load sharing among parallel corridors, enhancement of transient stability, mitigation of system oscillations and voltage (reactive power) regulation. Performance analysis and control synthesis of UPFC require its steady-state and dynamic models. Reference [ 11 introduces a steady-state UPFC model based on a single, ideal, series voltage source. Reference [3] utilizes two ideal voltage sources, one in series and one in parallel as UPFC steady-state model. The steady-state UPFC model suggested in [4] is based upon one ideal, series voltage source, and one ideal, shunt current source. The above steady-state models are based on simplifying assumptions and consequently have various limitations. A two-source UPFC steady-state model including source impedances is suggested in [5]. The primary objective of this paper is to develop steadystate and dynamic models of UPFC for power flow analysis, transient stability investigation and eigen analysis. Typical applications of the models are presented, and where applicable the EMTP is used to verify the accuracy of the developed models.
