dc.description.abstractenRelevance of the research. The world power industry has traditionally developed through the centralization in the creation of increasingly powerful energy equipment and its integration into energy complexes. As a result, large territorially long energy systems have been formed: European ENTSO-E, UES of Russia, UES of Ukraine and others. In recent years, there has been a stable tendency to change the general concept of energy development. We are talking about the introduction of a new ideology - energy of sustainable development. An important element of such an ideology is the significant use of distributed generation (DG) sources - low-power power plants. Introduction of DG sources in electrical networks (EN), in particular built on the basis of use renewable energy sources, in addition to reducing the environmental impact and solving many problems related to emissions and waste in production electricity, will, firstly, significantly increase the efficiency of the use of primary re- resources and - in the future - to reduce the cost of electricity, and secondly, to unload distribution network (DN), and finally, "push" the process of modernization of electrical objects and thus increase the reliability of electricity supply. This, in turn, will allow decrease the risks associated with further increases in energy prices. But there are number of technical issues related to the impact of DG sources on planning, organization of operation and control of electrical networks. The purpose of the research is to study issues related with the growing spread of use of renewable energy sources in distribution network and how to effectively solve them. To achieve this goal, the following tasks were set and solved: - the analysis of the current situation with distributed generation in the world; - investigating the impact of DGs on the operation of the distributed network. - the possibility of using effective electronic devices to solve problems related to DGs integration in electrical networks; - to study forecasting techniques for the efficient use of electronic devices and other communication equipment. The object of research. Processes of electricity distribution in electrical networks with local energy sources. The subject of research is the optimization electrical networks in the context of increasing use of renewable energy sources. Practical value of the results. To solve the set tasks in the dissertation the effectiveness and usefulness of the electronic SOP technology and one of the methods of load forecasting for the more effective operation of distribution networks were considered. Scientific novelty of the obtained results. For the first time, a comprehensive analysis of the feasibility of using complex of devices of power electronics for the purpose of increase of efficiency distribution networks under conditions of wide integration in them of various distributed sources of electric power generation, which will allow to evaluate the effectiveness of their use in power systems of Ukraine. The method of justification of Soft Open point technology application during the control modes of distribution networks with the distributed power generation sources has been further developed, which allows minimizing electric power losses. Improved the method of forecasting under conditions of uncertainty of the available input information in order to determine the expected network nodes loads and output power of the distributed power sources, which allows to increase effectiveness of application of remotely controlled switching centers application of remotely controlled switching devices distribution grids.uk
