Recently, research activities on the fields of the power system frequency controls are increasing, especially in connection with the deregulation of power systems. The main contribution to the generation controls required for the frequency controls comes from the thermal power plants with steam boilers. This article presents the fundamental features of MW response of the thermal power plants to be considered in dynamic simulations of the frequency controls, after reviewing the basis of the frequency controls in normal conditions of power systems. The features of the MW response are described in the aspects EDC operation, LFC operation and governor speed-droop operation.
