A model of the economic optimization of a composition of regulating power units in TPP taking the dynamic cyclic load capability into account is developed. The necessary conditions for maintaining the power grid’s frequency in accordance with modern standards are considered. The model foresees the use of electrothermal consumer-regulators constantly switched-on during the operation of a system. These consumer-regulators can consist of many high-power electrothermal conversion plants (such as heat pumps), which are installed in available heat supply systems.The model was tested on an example that matches the general features of the integrated power system of Ukraine. According to the model calculations, it is determined that the current composition of TPP cannot independently ensure the required standards for the recovery rate of power in the integrated power system of Ukraine in the case of a powerful unit failure (condition “N-1” ENTSO-E). It is necessary to use consumer-regulators with capacities from 350-400 MW to 1000 MW to eliminate the power shortage. This will ensure not only the necessary time transients for the elimination of an estimated incident, but also will improve the efficiency of thermal power plants by reducing the value of spinning reserve of the supplementary regulation.
