This article describes the development of an automatic generation control algorithm, which is capable of using accurate real-time unit data and has control performance advantages over existing algorithms. Utilities use automatic generation control to match total generation and total laod at minimum cost. Since it is impractical to measure total load directly, it is determined from total generation for a control area, the total tie-line flow error, and a component proportional to the frequency error. One part of the AGC system then assigns this total generation requirement to all the generators in the control area in an economic manner by using an economic dispatch algorithm. Another part of the AGC system keeps track of each generator and attempts to correct individual unit errors and total system errors that can be caused by unit response problems, normal changes in system load, metering errors, and system disturbances.
