Research on the Economic Efficiency of using Eco-Designed Transformers in the Electric Grids of the Unified Energy System of Ukraine
Abstract
Abstract. The article investigates the economic feasibility of implementing eco-designed power transformers in the distribution electricity networks of Ukraine's Unified Energy System. Special attention is given to the analysis of energy losses during the operation of such transformers, which was carried out in accordance with the methodical recommendations of the Ministry of Energy and Coal Industry of Ukraine.
Calculations were made for TMH-1000/10 type transformers in various operational modes, allowing for the assessment of their performance under real-world operating conditions. The economic benefits were evaluated using the net present value (NPV) method, which made it possible to compare the potential financial advantages of using eco-design with traditional transformer equipment options.
The analysis showed that, despite the potential reduction in energy losses, the capital expenditures for implementing eco-designed transformers are significantly higher compared to traditional models. As a result, under current economic conditions and tariff policies, their application in the distribution networks of the Distribution System Operator does not provide sufficient economic benefit.
The obtained results may be useful for energy companies, regulatory authorities, and researchers when making decisions regarding the modernization of the electric power infrastructure. The conclusions of the study could also serve as a foundation for further scientific work aimed at optimizing the parameters of power transformers, taking into account both energy and financial indicators.
