A novel power flow model of a Static Synchronous Series Compensator (SSSC)

This paper presents a novel Newton Raphson Power Flow model of a Static Synchronous Series Compensator (SSSC). The SSSC is a voltage sourced converter (VSC) based series FACTS device. This model includes multiple control modes of the SSSC. The SSSC is operated on following control modes: 1) the active power flow on the transmission line; 2) the reactive power flow on the transmission line; 3) the voltage at the sending or receiving end bus. In this model, the impedance of coupling transformer is included with the transmission line impedance. Numerous case studies carried out with multiple SSSCs incorporated in the IEEE-30 bus test system validates the proposed model.
