This paper deals with discrete-mode automatic generation control of an interconnected reheat thermal system considering a new area control error (ACEN) based on tie-power deviation, frequency deviation, time error and inadvertent interchange. Optimum integral and proportional integral controllers using the concept of stability margin and ISE technique have been obtained with conventional ACE and new ACE, and their dynamic performances compared for a step load perturbation. Results reveal that regulator based on the new ACE concept always guarantees zero steady state time error and inadvertent interchange unlike in the case of a controller based on conventional ACE. The settling time for tie-power and frequency deviations is however, somewhat more with the controller based on new ACE.
