Application of Genetic Algorithm based PSS for two - area AGC system in deregulated scenario

This paper proposes an approach for the design of multiple power system stabilizers (PSS) for multi-area automatic generation control (AGC) system with new deregulated scenario. Here, the concept of DISCO participation matrix (DPM) is also included. The analysis is conducted considering three pre-defined cases, out of which one is the violation of contract case. The optimal parameters of the PSS are obtained employing genetic algorithm (GA) using integral of time multiplied absolute value of the error (ITAE) error criteria. A two-area non reheat thermal system is considered to exemplify the optimum parameter search.
