Optimal allocation of transmission rights in systems with FACTS devices

Financial transmission rights (FTR) is a market-based approach to transmission congestion management, which is essentially based on the locational marginal pricing (LMP) theory. FTR auction is an important method of allocating transmission capabilities to the market participants who value them most. A DC power flow model is applied to the FTR auction. To improve the result and the revenue of the FTR auction, two types of series FACTS devices are modelled as additional power injection at buses in the presented linear optimisation problem of FTR auction. Some new special treatments have been done on the TCSC operating limits to keep the auction problem linear. The impacts of controlling different FACTS devices on auction results are shown by detailed studies of an eight-bus test system and the IEEE 30-bus test system
