Энергетическая сфера Объединенных Арабских Эмиратов: традиции и инновации
The Arab countries of the Persian Gulf, basing its development on natural resources, in this century has made considerable economic results and literally jumped in the modern world, overtaking on a range of financial and economic indicators leading European and Asian States - largely due to the development of the oil and gas industry.
In this paper the algorithm for battery charge control of renewable energy sources - wind turbine and solar panel. Every operating block is also described with specifying the dependencies. The principle of the charging current limitation that prevents battery failure as a result of a strong internal resistance increase while preliminary deep discharge is considered.
The autonomic power supply system for wireless sensor network based on renewable energy sources was developed. The main factors affecting its operation during the use of main gas pipelines as a part of detection system gas leak. An adaptive algorithm for the battery charger operation and the transceiver module are proposed. The selecting technique of the preferred source of energy depending on the given region is presented below.
Given the specificity of Russia can be said that the development potential microgrid very high, but the level of its use will depend on the model for the energy sector development. In this article the basic model for this development, given their estimate with the benefits and risks. The results of the pilot study, the authors of the effectiveness of model projects microgrid in Far Eastern Federal District (FEFD).
This paper presents an overview of the key issues concerning approaches to the technical regulation for distributed generation (DG) at the national (Germany and Denmark) and European (ENTSO-E) levels, and review of generic structure and composition of the technical regulations for DG. Special attention is paid to the issue of DG performing in different frequency deviations and the experience of ENTSO-E in this respect, including the impact of DG impact on reliability of Continental Europe’s power system.
During the period up to 2040, renewable energy sources (RES) will have the highest growth rates of all forms of energy. Based on the calculations on the world energy model incorporated in the SCANER modelling and information complex (working on the basis of optimization, econometric analysis, and balance approach), key trends in the world consumption of renewable energy sources; the share of OECD and non-OECD countries in the use of the renewable energy sources; consumption of renewable energy sources by type; end use and the impact on the electricity sector during the period up to 2040 were observed. The main finding of the paper is that RES are becoming more competitive and therefore will be used on an increasingly wide scale not only in the OECD countries, but also in the whole world. At the same time, due to the fact that RES start their take-off from a modest basis, they will only have a limited influence on the shares of hydrocarbons in the energy mix.
A scenario-based prognosis of the evolution of global power generation markets until 2040, which was developed using the Scaner model-and-information complex, was given. The perspective development of fuel markets, vital for the power generation industry, was considered, and an attempt to predict the demand, production, and prices of oil, gas, coal, and noncarbon resources across various regions of the world was made. The anticipated decline in the growth of the global demand for fossil fuels and their sufficiency with relatively low extraction expenses will maintain the fuel prices (the data hereinafter are given as per 2014 prices) lower than their peak values in 2012. The outrunning growth of demand for electric power is shown in comparison with other power resources by regions and large countries in the world. The conditions of interfuel competition in the electric power industry considering the changes in anticipated fuel prices and cost indicators for various power generation technologies were studied. For this purpose, the ratios of discounted costs of electric power production by new gas and coal TPPs and wind and solar power plants were estimated. It was proven that accounting the system effects (operation modes, necessary duplicating and reserving the power of electric power plants using renewable energy sources) notably reduces the competitiveness of the renewable power industry and is not always compensated by the expected lowering of its capital intensity and growth of fuel for TPPs. However, even with a moderate (in relation to other prognoses) growth of the role of power plants using renewable energy sources, they will triple electric power production. In this context, thermal power plants will preserve their leadership covering up to 60% of the global electric power production, approximately half using gas.
