Static Synchronous Series Compensator (SSSC) to Improve Power System Security

Abstract

In the electricity market competition, there is more power exchange with reverse power sharing. The key challenge is to make electrical energy available in the majority of areas at the lowest possible cost and with the best level of dependability. As a result, the transmission network must run at or over one or more transfer limitations, causing transmission line congestion. Proper usage of reactive power compensation based on FACTS devices can alleviate these transmission line issues. The major goal of this research is to improve the performance of the power system using a static synchronous series compensator (SSSC). The suggested controller's performance is assessed under various conditions. According to the simulation findings, the PI-based SSSC successfully manages the power flow in a disturbed state. As a consequence, the suggested SSSC-based controller provides efficient damping control, improves system profile voltage under various load conditions, and increases power system security.
