WebIn an electric power system, automatic generation control ( AGC) is a system for adjusting the power output of multiple generators at different power plants, in response to changes in the load. Since a power grid requires that generation and load closely balance moment by moment, frequent adjustments to the output of generators are necessary. WebIf the grid frequency is dropping below the target (usually 50Hz or 60Hz), they'll request more generation from those generators that are online and scheduled for frequency regulation duty. The grid operators control voltage by ordering more or less reactive power to be delivered to the grid.
