Abstract

This paper discusses, through a review of the main methodologies, the representation of static var compensators (SVCs) in the power flow problem. One of the methodologies, consisting of a full Newton formulation of the problem, considers the thyristor’s firing angle as a state variable. The other methodology, also in full Newton formulation, proposes a model in which the SVC is represented considering the reactive power injected into the bus as a state variable. Furthermore, an improvement to the firing angle methodology is proposed in order to consider the voltage droop in the SVC’s linear region of operation. All methodologies are validated through the study of two test systems. The first system is a 3 bus tutorial system and the second is the well-known IEEE 118 bus system. The results presented validate the methodologies under study and the improvement in the equation of the linear region of operation for the first methodology.
