Optimal combination of centralized and autonomous methods of energy supply to consumers with combined production of electrical and heat energy in the heat supply systems of large cities of Uzbekistan

Abstract

from the threat of shortages in the provision of economically accessible and normatively necessary energy resources of acceptable quality in normal and emergency circumstances. Energy security, reliable and efficient operation of energy generating facilities are the most important criteria for a high level of social well-being. To ensure reliable and efficient operation of the energy system, the following have been developed and approved at the state level: the Concept of providing the Republic of Uzbekistan with electrical energy for 2020–2030. The main goal of the Concept of providing the Republic of Uzbekistan with electric energy for 2020-2030 is to meet the growing demand for electric energy at competitive prices and the dynamic development of the electric power industry of the Republic of Uzbekistan through the modernization and reconstruction of existing power plants, the construction of new generating capacities based on highly efficient energy production technologies, improvement electricity metering systems, diversification of fuel and energy resources with the development of the use of renewable energy sources. Resolution of the President of the Republic of Uzbekistan No. PP-4249 March 27, 2019 “On the strategy for further development and reform of the electric power industry of the Republic of Uzbekistan.” One of the priority areas for ensuring energy security is the development of autonomous energy with the introduction of modern installations for the combined production of thermal and electrical energy, including gas turbine and gas piston units and gas generators.

Aim: to show the possibilities of an effective combination of centralized and autonomous methods of energy supply to consumers with the combined production of electrical and thermal energy in heat supply systems of large cities of the republic.

Objectives: study of centralized and autonomous methods of energy supply to consumers when switching to combined production of electrical and thermal energy at thermal power plants and boiler houses. Technical and economic analysis of options for converting thermal power plants and boiler houses to cogeneration.
