Application of GSA optimized controller parameters in automatic generation control for interconnected power system with governor dead band

This paper analyzed the performances of Gravitational search algorithm (GSA) based Proportional-Integral (PI) and Proportional-Integral-Derivative (PID) controller for Automatic Generation Control (AGC) of an interconnected power system two area non reheat thermal system with Governor dead band nonlinearity. The Integral time multiplied squared error (ITSE) and Integral Square Error (ISE) uses in order to increase the performances of the controller. The performances of the proposed PI and PID controller are compared with recently published papers Craziness base based Particle Swarm Optimization (CPSO) technique PI Controller for the same system.
