Abstract :
This article proposes automatic generation control (AGC) of an interconnected three equal and unequal hydro-thermal system with DB non-linearity. Moreover, the self tuning control scheme of superconducting magnetic energy storage unit (SMES) is performed to investigate the performances of AGC problem. Dynamic responses of SMES connected AGC are compared with that of integral (I) and proportional-integral-derivative (PID) controlled AGC. Frequency deviation signal is used as an input to SMES. Integral square error approach with Biogeography based optimization algorithm is used to find optimum values of controller parameters. 1% step load perturbation in either area is considered for simulation study. Simulation study exhibits significant effect of designed SMES based controller on the dynamic performances of an interconnected power system with sudden load perturbation.
