Algorithm for Calculating the Dispatch of Multiple Power Flow Control Devices using Current Sensitivity Factors

This paper presents an algorithm to determine the required series voltage injection setpoint for multiple Modular Static Synchronous Series Compensation (M-SSSC) installations. These devices are part of the Flexible AC Transmission Systems (FACTS) family, and one of its main objectives is to allow power flow control to enhance grid utilization. With the proposed algorithm, it is possible to automatically reach the required magnitude for a set of line currents, which can be associated to the line’s thermal limit or to preferred operational setpoints. Additionally, the algorithm performance is tested in different power systems, identifying systemic benefits such as wide-area control, grid capacity optimization, system reliability and security, and facilitating the integration of renewable generation.
