The review of the possibility to increase the integrated power system of Ukraine' balance reliability by implementing electric heat generators

Abstract

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".

Prospective Directions for the Modernization of the Load Control System of the Central Energy System of Ukraine

“…Table 1 shows the data of NEC "Ukrenergo" regarding the installed capacity of TPPs operating in the UESU, the number of installed power units, and the specific consumption of conventional fuel g/kWh. The presence of most of the capacities of the TPP in the basic part of the SDEL of the NPP reduces the potential opportunities for using the generating capacities of the NPP and restrains their further development and commissioning [2].…”

“…Thus. it will be necessary to carry out appropriate modernization in the system of dispatching control of the load mode of the UES which will make it possible to achieve better indicators of energy economic and environmental efficiency of the power system [3,4].…”
