Two-area AGC in interconnected system under the restructured power system using BFO controller

This paper presents the bacterial foraging(BF) optimization control technique for designing the integral controller gain, which is applied to AGC in interconnected multi-area system under the deregulated environment (considering all practical aspects) to control the tie line power and frequency of the interconnected system. Each area´s comprises of one hydro and one thermal generating station. Further each area has two GENCO´s and two DISCO´s which have bilateral contract with each other. Three different cases of disturbances in the system are considered and controllers gain are optimized using BFO. The optimized gain is used in the system to improve its performance. MATLAB-SIMULINK is used to study the performance of the system.
