New approach to power system stabilizer optimization techniques

Power System Stabilizers (PSS) are control devices used in synchronous generators to enhance the stability and damping of power systems by providing supplementary control signals to the generator excitation system. It’s come in various types, each designed to address specific stability issues and accommodate different system configurations, Conventional Lead-Lag PSS, Phase-Compensation PSS, High-Speed PSS and Wide-Area PSS. Multi-area transitional stability hinges on the ability of a power system consisting of multiple interconnected areas or regions to maintain synchronous operation following a disturbance, such as a short circuit or a disturbance in the load. Ensuring transient stability in such systems is crucial for preventing cascading failures and blackouts. The proposed control illustrates the implementation of different strategies for PSS using the four machines two-area kundur test system.
