Automatic Generation Control is the controlling link between the dispatch office and the generating plants that it supervises. The automatic generation control function (AGC) is assigned the responsibility of adjusting generator outputs to meet the overall system objectives. The AGC system is a compendium of equipment and computer programs implementing closed loop feedback control of frequency and net interchange. Generator outputs, tie-line flows, and frequency are measured, compared with setpoints, and adjusted to correct error in the controlled quantities. This paper reviews the AGC function as implemented by a modern dispatch office digital computer system.
