A versatile FACTS device model for powerflow and stability simulations

While early FACTS devices consisted mainly of thyristor-controlled/switched RLC/transformer components, the newer generation is based on the self-commutated voltage-source power converter. The variety of devices and applications, and the changing nature of the technology, call for versatile modelling capabilities at different levels of detail. This paper describes a model conceived as a coordinated and interconnected set of controllable shunt and series elements. For each device, functional characteristics, typical settings and controls, and simulation examples are presented. The model is capable of representing virtually any FACTS device for powerflow and all types of stability simulations
