The State and Prospects of Hydroenergy of Ukraine

Abstract

The features and the analysis of the program of development of hydropower of Ukraine till 2026 are determined. It is shown that at present, the use of hydroelectric and hydroaccumulation plants to cover peak loads, both in terms of both technical and economic and environmental performance inferior to more advanced methods. New technologies of coating peak loads, frequency and power regulation in power systems that are able to compete successfully with hydroelectric power plants are considered. Determine the minimum volumes of maneuver capacity that the Joint Energy System of Ukraine should have in its composition. A comparative analysis of technical and economic and environmental characteristics of the project of the Kaniv hydroaccumulation plant and an alternative project for the construction of a complex of consumers-regulators on heat pump installations is performed. On the example of the project implementation, the compaction of the schedules of electrical loads by the introduction of

Possibilities and Perspectives of the Consumers-Regulators Application in Systems of Frequency and Power Automatic Regulation

“…Ukrainian HPP are flat, low-water and low-power, their capabilities are not enough even to cover the variable part of the electric loads schedule (ELS) of the Ukrainian IES. Over time, this situation will only worsen, since the possibilities of the hydroelectric power stations capacity increasing are practically exhausted, and the of electricity consumption in the country will increase with the simultaneous decompression of ELS [8]. Thus, in the conditions of Ukraine, when trying to build a subsystem of secondary regulation in AFPCS according to the traditional scheme, the only possible option is the use of reconstructed pulverized coal power units in the role of generator-regulators.…”

Model of Optimal Use of Hydro Power Plants in the Electricity Market

“…Крім того, ГЕС найчастіше отримують від диспетчерської служби аварійні заявки на завантаження чи розвантаження генераторів. Така активна участь ГЕС у процедурах підтримки операційної безпеки режимів [11][12][13] Сумарна вигода від продажу електричної енергії та послуг в кожному j-му ринковому сегменті розраховується окремо для кожного i-го генератора ГЕС. Такий підхід дає змогу точно врахувати особливості кожного генератора ГЕС та приведені до цього генератора витрати, пов'язані з виробничою діяльністю та участю у ринкових сегментах…”
