Universal method for the modeling of the 2nd generation FACTS devices in NewtonRaphson power flow
In this paper a universal approach to the modeling of the 2nd generation FACTS devices for power-flow calculations by applying the NewtonRaphson method for current-based models is discussed. First, the basic principles of modeling 2nd generation FACTS devices using current-based models and the current-based models themselves are presented. This is followed by a discussion about the universality of the proposed model. Next, a definition of the FACTS devices free parameters, a mathematical description of their type, the problem of the initial conditions and the handling of constraints are discussed. The derived model was then tested on the IEEE 57, IEEE 118 and IEEE 300 bus systems. Finally, the main achievements are summarized.
