The paper considers one of the possible options to solve the actual task for the Integrated Power System (IPS) of Ukraine regarding creating deficit-free primary, secondary and tertiary reserves, which is an important condition for successful integration of IPS of Ukraine into ENTSO-E. The increase of the level of reserves of IPS of Ukraine could be provided by the implementation of the dedicated technological system (NPP+powerful electric boilers) which should be connected at the "points" where a nuclear power plant (NPP) is connected to the grid. It is assumed that the use of the proposed technological system with electric boilers' capacity of 2000 MW in the IPS of Ukraine will allow the substitution of about 10 thermal power plant's (TPP) units, which provide secondary reserves. Implementation of proposed option also aimed at fulfillment "National Plan on Reduction of Emissions from big burning units", and also allow reduce consumption of organic fuel, namely the coal, that is prescribed by Energy Strategy of Ukraine till 2035. According to preliminary estimates, the proposed technological system complies with the main categories of "Methodology for the analysis of costs and benefits of projects for the development of electrical networks".

The article presents the results of determining the power and ecological indicators of the implementation of innovative control technology of the Integrated Power System (IPS) of Ukraine using electric heat generators (EHG). This control technology is based on the use of modern principles of interaction of power-generating and heat-generating systems, which will take place during the performance of Daily curve of electricity load (DCEL) compaction processes controlled by the load of EHG complexes. The implementation of this control technology involves the introduction in the IPS from 1 GW to 2 GW of electric power EHG systems. A simplified method of calculating the amount of electricity to ensure the operation of EHG complexes during the year. During the compaction of DGEN in the hours of night falling during the year will be generated an additional 3,629 billion kWh of electricity. If this energy is generated by the existing coal-fired thermal power plants, an additional 1659.2 thousand tpp/year will be consumed. The thermal energy that will be produced at the EHG will reduce the consumption of natural gas for heating and the hot water by gas boilers of district heating systems. The operation of EHG complexes will save 353.5 million m3 of natural gas. The results of calculations of ecological and power indicators in the implementation of EHG for the control of IPS are presented for two successive stages. At the first stage, an increase in the minimum level of DCEL by 1 GW is considered. This will allow to move away from the daily practice of stopping 7-10 power units of coal-fired power plants. In the second stage, an increase in the minimum level of DCEL by another 1 GW is considered. This will allow to change about 25 maneuverable power units of TPPs with a capacity of 200 and 300 MW each to the basic mode of operation during the night falling of DCEL. With the use of this control technology it will be possible to form in the IPS self-sufficient reserves of shunting capacity for secondary and tertiary power regulation in the power system. Increasing the share of thermal power plants that will operate in the basic mode of electricity generation allows us to consider the possibility of replacing thermal generation with nuclear power plants in the future.
