Abstract

Scaling up the use of alternative and renewable energy sources necessitates a substantial improvement of energy conversion processes and improve technical and economic characteristics of power supply systems based on them. One of the main ways to solve this problem is to intensify energy conversion processes at all levels of the system, both during energy generation and its consumption, which necessitates a systematic study of the dynamics of energy conversion processes in key elements of the technological scheme. As promising projects that could be implemented in the shortest possible time with maximum economic, can be divided into work that aims to improve the efficiency of wind energy infrastructure and solar energy sector using hydrogen technologies. Innovative hydrogen technologies designed to play an important role in the diversification of energy flows, significantly reduce the consumption of hydrocarbon fuels and will improve the environment in the most environmentally stressed areas of industrial regions and rural arias. Solar electricity generation steadily increased its share in the world's energy balance. Among the main obstacles to efficient use of the energy potential of solar radiation should underline its low density and high revenues as uneven during daylight hours and, depending on the season. The way to overcome or minimize these obstacles may be the creation of specialized systems of concentrating solar energy combined with energy storage systems or production of clean fuels. The paper presents the results of mathematical modeling of static parabolic-concentrator for the photovoltaic system and demonstrate possibilities use of concentration may not only increase the energy efficiency of solar cells, while reducing the use of expensive semiconductor materials, but also smooth the unevenness of incoming solar radiation and improve economic and operational performance, including the use of renewable energy sources. Use concentration system constructed during the year will in 2.3 times increase revenues solar radiation per unit area, while reducing seasonal fluctuations of the level of solar radiation on the surface of the receiver by 14%.
