Abstract: The master’s thesis is dedicated to the study of energy efficiency and resource performance of medium-sized wind turbines operating in parallel mode. The research provides a comprehensive analysis of global trends in wind energy development, evaluates its prospects in Ukraine, and examines key factors influencing the operational efficiency of wind power plants (WPPs). Special attention is given to analyzing the performance of the Botievo WPP, its contribution to the country’s energy balance, as well as the technological and economic aspects of wind energy development in Ukraine. The introduction highlights the relevance of the study, considering the growing importance of renewable energy sources globally and Ukraine’s need for energy independence. Wind energy is viewed as a pivotal tool to achieve these objectives due to its environmental benefits and significant development potential [1]. The first chapter analyzes global trends in wind energy development. The experience of leading countries, such as Germany, Denmark, the United States, and China, in implementing advanced technologies to enhance wind turbine efficiency is examined. Emphasis is placed on the role of innovations, particularly in improving blades, gearboxes, and control systems [1]. The feasibility of adapting global best practices to Ukrainian conditions is also assessed. The second chapter presents an in-depth analysis of the Botievo WPP, one of Ukraine’s largest and most advanced wind power plants. Its technical characteristics, including wind turbine types, layout, and nominal capacities, are reviewed [2-3]. Actual data on electricity production are analyzed, and its impact on grid stability and carbon emission reductions is evaluated [3]. The third chapter focuses on analyzing daily load coverage graphs and power balance. Special attention is given to studying the impact of wind conditions on WPP productivity, evaluating the dynamic characteristics of wind turbines, and requirements for their operational stability [4]. The object of the study is medium-sized wind turbines operating in parallel mode. The subject of the study is methods to improve energy efficiency and optimize the operation of such turbines within the power grid. The aim of the research is to investigate global and national trends in wind energy development, analyze the performance of medium-sized wind turbines, and develop recommendations for optimizing their operation to enhance energy efficiency and ensure the stability of Ukraine’s power system.
