Abstract :
This paper discusses the effect on transmission congestion management and pricing of dynamic and steady-state models of FACTS controllers. The analysis is based on comparing system operating conditions and locational marginal prices obtained from stability-constrained auction models when dynamic and steady-state FACTS models are used. A novel stability-constrained OPF auction model, which allows for the inclusion of dynamic models of power systems elements, including FACTS controllers, and a better representation of system stability constraints, is described in some detail and applied to the IEEE 14-bus benchmark system with a SVC. The paper demonstrates the importance of considering the dynamic effects of FACTS controllers on transmission congestion management and pricing
