Item type:Наукова стаття, Optimisation of energy solutions: Alternative energy, reactive power compensation, and energy efficiency management(2023-11-22) Bandura, Andrii; Romaniuk, Mykola; Komenda, Nataliya; Hadai, Andrii; Volynets, VladyslavThe relevance of the problem under study is determined by the need to create a sustainable, efficient and environmentally safe energy complex. The growth of the world population, industrial development, and overall energy demand endanger the provision of society’s energy needs, making the need for research urgent at the present time. The purpose of the study is to examine optimal energy optimisation strategies, including alternative energy, compensation of reactive power, and energy efficiency management, to ensure the stable and efficient functioning of the energy complex. Among the methods used, analytical, classification, functional, statistical, and synthesis methods were applied. In investigating the optimisation of energy solutions, a thorough analysis of various aspects of alternative energy, reactive power compensation, and energy efficiency management was conducted. This analysis encompassed various aspects and parameters related to these areas, including technical, economic, and environmental indicators. As a result of the study, it was established that alternative energy has significant potential for ensuring sustainable development of the energy system. It can serve as a reliable source of energy that does not harm the environment and is not dependent on limited resources. In addition, reactive power compensation was recognised as an effective way to avoid energy losses in the system. This strategy helps to ensure more efficient energy use and reduce losses during transmission and distribution. Energy efficiency management also proved to be a key aspect in achieving energy supply sustainability. This allows optimising resource utilisation, reducing energy costs, and mitigating the negative impact on the environment. The practical value of the study lies in the development of innovative recommendations and strategies for energy optimisation, which will contribute to the creation of a stable, efficient, and environmentally safe energy complex and enhance its compliance with current and future challenges, making a considerable contribution to the development of science and the energy sector.Item type:Наукова стаття, Estimation of the total influence of methods for increasing the line natural load(2024) Komenda, Nataliya; Volynets, Vladyslav; Hrytsiuk, Iryna; Bandura, Iryna; Romaniuk, MykolaStudies aimed at the economically sound increase in the capacity of existing power lines and improvements in their design are relevant today. In addition to the well-known design methods of influencing the capacity of the transmission line, there are other meanings that can affect its natural capacity, which is directly related to the capacity. Therefore, the purpose of this study was to find possible methods of increasing natural power and evaluate their effectiveness in real configurations. The basis of the methodological approach applied in this study is a qualitative combination of methods of systematic analysis of ways to increase the capacity of power lines with the analytical investigation of the prospects for its impact on wave resistance to increase the natural power of the line. The conducted research determined the total influence of the analyzed factors on the increase in transmission capacity and identified the most optimal configuration from a technical and economic standpoint. Based on the results of the calculation of the natural capacity of the configurations, conclusions were made about the significance of the impact of each of the above factors, and the economic effect of their implementation in the integrated power system was established. Improvement of this methodology can, in the long run, serve as a tool for calculating configurations for economic and technical relevance, or serve as a foundation for further identification of factors affecting the transmission capacity of power lines.
