A Simple Three-Phase Model for Distributed Static Series Compensator (DSSC) in Newton Power Flow

Load flow problems have always been an important issue in power system analysis and require proper modeling of system components. In this regard flexible AC transmission system (FACTS) controllers are modern devices that their modeling specially the series type is a challenging topic. This paper describes a three-phase model for distributed static series compensator (DSSC) based on extending the static synchronous series compensator (SSSC) model in Newton power flow. To extend the SSSC model the following two differences must be considered; three completely independent phases and the existence of several modules in a DSSC system. Simulation results on the IEEE 30-bus system and a five bus test system illustrates the feasibility and performance of the proposed model in Newton power flow algorithm.
