Abstract
The Unified Power Plow Controller (UPFC) is a flexible AC Transmission Syst em (FACTS) device capable of controlling line flows and terminal voltage. I n order to analyze its true effects on power systems, it is important to mo del its constraints due to various ratings and operating limits. Innovative techniques are introduced in this paper for fast power flow conv ergence with various UPFC control modes and simultaneous multiple limits en forcement, while the line side bus remains explicitly accessible. An effici ent algorithm is developed for applying the line side voltage limits, which avoids the possible hunting between shunt and series converters of UPFC. Control models with similar constraints are also developed for stability st udies. Simulations are performed using EPRI's Power Ssystem Analysis Packag e (PSAPAC).
