Adaptive automatic generation control with superconducting magnetic energy storage in power systems

An improved automatic generation control (AGC) system employing self-tuning adaptive control for the main AGC loop and the superconducting magnetic energy storage system (SMES) is presented. Computer simulations on a two-area interconnected power system showed that the proposed adaptive control scheme was very effective in damping, oscillations caused by load disturbances and its performance was quite insensitive to controller gain parameter changes of the SMES system. A performance evaluation of control schemes using adaptive and nonadaptive controllers in the main AGC and in the SMES control loops is presented. The improvement in performance resulting from the adaptive scheme was particularly pronounced for load changes of random magnitude and duration
