Application of Search Group Algorithm for Automatic Generation Control of Interconnected Power System

Abstract

A novel search group algorithm (SGA) technique with PID controller is proposed for an application toward multi-area interconnected power system-based automatic generation control (AGC). A reheat thermal power system over three unequal areas is considered. The system includes the nonlinearity parameters such as GRC and GDB. The supremacy of SGA tuned PID controller is projected with a comparative empirical result over recently published firefly algorithm (FA) optimized technique tuned PID controller for the similar multi-area power system which is interconnected. Simulation study confirms that the proposed SGA technique is better as compare to FA technique for the system.
