EVALUATION OF THE EFFICIENCY OF WIND GENERATORS IN THE CONDITIONS OF PARTICIPATION IN THE DAILY ELECTRICITY MARKET
Kostiantyn POKROVSKIY – Candidate of Technical Sciences, Associate Professor of Electric Power Engineering and Control Systems Department of NU "Lvivska polytechnika" (48/5 ak. Saharova St., Lviv, 79013, Ukraine., e-mail: kpokrov@gmail.com, https://orcid.org/0000-0003-4151-5820).
In its development, the global energy sector is constantly demonstrating the growth of electricity consumption. Traditional power plants in this process ensure an increase in greenhouse emissions and aggravation of climate problems, which are becoming more relevant every year. Against this background, modern alternative energy sources, namely wind power plants, contribute to reducing the impact of traditional power plants and promote solutions to address environmental problems. The development of the global wind energy industry is accompanied by an intensive increase in the unit capacities of wind power generators. The paper analyzes the efficiency of a wind power plant based on modern wind generators for predetermined location conditions, taking into account operating costs based on operating experience and based on the assessment of the power plant's participation in the balancing electricity market and taking into account the "green tariff". Calculations of technical and economic indicators of a hypothetical 4-unit wind power plant with various wind generators under the wind conditions of a predetermined industrial site located in the Carpathian region of Ukraine were carried out. The calculations take into account modern typical characteristics of wind generators, additional operating costs and the estimated cost of electricity in the conditions of a balancing electricity market and in the conditions of the application of the "green tariff" for the comparison of overall efficiency.
Additional operating costs, including equipment maintenance and disposal of worn turbine blades, were considered and found to have minimal impact on the overall cost structure, contributing only 5-7% to total expenses. The findings confirm the efficiency of constructing wind farms with modern wind generators in the Carpathian region, particularly when integrated into the balancing energy market, supporting the transition to renewable energy and reducing reliance on traditional fossil fuels.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016).
