Banozadeh S. Models and methods of estimating the integration efficiency of distributed generation sources into distribution networks.

Object of research: the process of forming modes of distribution networks in the conditions of integration into them of sources of dispersed generation. The purpose of the work is to improve and develop theoretical methods of integrated assessment of the influence of distributed generation sources on the modes of operation of electrical networks of different classes of nominal voltages for choosing their use variants, which create the most favorable conditions for the formation of integrated distribution networks and ensure their effective work. Methods of research: fundamental laws of electrical engineering, methods of mathematical modeling, the theory of operations research and experiment planning, elements of the theory of reliability, methods of probabilistic statistical modeling, algorithms of multicriteria decision making, entropy method of determining the weight coefficients of individual criteria. Theoretical and practical results and novelty: the theoretical methods of complex estimation of the influence of distributed generation sources on the modes of operation of electric networks of different class of nominal voltages for the choice of their application variants, which create the most favorable conditions for the formation of integrated distribution networks with ensuring their effective operation, are improved. Subject and degree of implementation: the results of work are used in the development of a project for the integration of distributed generation sources into the centralized electricity supply system of the city of Shiraz (Iran) and recommended for use in the form of methodological recommendations for improving the reliability of air distribution networks in conditions of the use of dispersed generation in LLC Engineering Innovation Company Energy Technologies ", as well as optimization of the topology of the adjoining them to the RM, including the appearance in their structure of sources of Distributed Generation, which became a part of the software for estimating the change of losses of electric power in the networks of 110 ... 220 kV, in Ltd Firma Elekon. Implementation efficiency: a coordinated solution to the problems of partitioning of air distribution networks and the integration of distributed generation sources can reduce costs by 15-20% to ensure normalized reliability of power supply in the conditions of the work of generation sources for the allocated load. Scope of use: Distributed Generation.
