This paper demonstrates the study of a price based frequency linked regulation for three area multi-unit Automatic generation control (AGC) under deregulated market scenario. In this work conventional secondary feedback control signal has been replaced through unscheduled interchange (UI) based price signal linking to the frequency at the prevailing time. The three area multi-unit power system mathematical model has been developed to incorporate the various types of transactions incident in a competitive electricity market and simulation is carried out using MATLAB/SIMULINK software. Particle Swarm Optimization (PSO) is used in optimizing the gain of integral controller of individual generating units. Simulation results exhibit the effectiveness of PSO in the tuning of gain of integral controller along with price based frequency linked regulations for system under study
