Анализ общих технических требований к объектам распределенной генерации при их интеграции в энергосистему
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.
Business Case is a part of the specialised Master Program and aimed to developing the key competencies of the discipline "Enterprise Information System".
Business Case describes process of the development Technical Reqirement for the developing and implementation ERP-system for the biggest wholesale/retail company.
With the proliferation of distributed generation, an electrical load can be satisfied either by a centralized generator or by local/nearby distributed generators. Given a set of resource demands in a collection of geographically co-located microgrids connected to the central grid, each such demand characterized by a power level and a duration. We study algorithms that allocate generation resources to demands by configuring switched paths from sources to loads. We consider the case when each demand can be met by two generators, one of them representing the central grid and thus shared among all demands.
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.
The article examines the main features of obligatory certification national systems in the transitional period of national technical regulations enactment in Russia and Customs Union of Eurasian Economic Community (EAEC).
The authors conclude that the full-scale development of distributed generation should be combined with introducing Smart Grid technologies which allow having an integrated energy system provided with an intellectual management system.
Development of distributed generation is one of the modern trends in the electric power industry worldwide. The main drivers are technology progress and energy policy (stimulating development of RES, cogeneration, “green energy”, etc.). Furthermore, consumers’ request for higher service standards is important. Liberalization of the electric power industry creates additional opportunities for the development of distributed generation. Also it is necessary to synchronize the development of the electric power industry, heat industry, and consumers’ generation.
Smoking is a problem, bringing signifi cant social and economic costs to Russiansociety. However, ratifi cation of the World health organization Framework conventionon tobacco control makes it possible to improve Russian legislation accordingto the international standards. So, I describe some measures that should be taken bythe Russian authorities in the nearest future, and I examine their effi ciency. By studyingthe international evidence I analyze the impact of the smoke-free areas, advertisementand sponsorship bans, tax increases, etc. on the prevalence of smoking, cigaretteconsumption and some other indicators. I also investigate the obstacles confrontingthe Russian authorities when they introduce new policy measures and the public attitudetowards these measures. I conclude that there is a number of easy-to-implementanti-smoking activities that need no fi nancial resources but only a political will.
One of the most important indicators of company's success is the increase of its value. The article investigates traditional methods of company's value assessment and the evidence that the application of these methods is incorrect in the new stage of economy. So it is necessary to create a new method of valuation based on the new main sources of company's success that is its intellectual capital.
