Kovalchuk O. Optimisation of normal modes of distributive electrical networks with the dispersed energy sources

Subject of inquiry - normal regimes of distributive electrical networks with nonconventional and renewed sources of the electric power. The work purpose are raise of technical and economic efficiency of joint maintenance of distributive electrical networks (DEN) and the dispersed sources of the electric power (DPS) at the expense of optimisation of circuit designs of joining last, and also control automation by regimes of their work. Methods of researches: the variational calculus mathematical apparatus, matrix algebra, methods of sensitivity analysis, a rule of the theory of automation control, the theory of factorial experiment. Theoretical results: for the first time on the basis of definition of address power losses in electrical networks and the analysis of their sensitivity the method of joining circuit design optimisation for DPS to networks which allows to provide decrease in losses of the electric power and voltage improvement of quality in them is developed; for the first time analytical conditions of an optimality for set of management problems by the dispersed energy sources of local electric systems as a part of an electropower system are offered; for the first time the method of formation of schedules of polytypic DPS teamwork in the electrical networks is developed, allowing to compensate negative agency of instability of generation of is conditional-operated energy sources. Practical results: аlgorithms and programs of circuit designs optimisation of joining of DPS to a DEN, optimisation of dispatching schedules of conducting a regime of small water-power developments, and also the block diagramme of the automated control system by the dispersed power complex from DPS are developed. Their application gives the chance to raise efficiency of functioning of DPS in a DEN, to reduce the cost price and to increase volumes of a power production them. Heading extent: results of work it is injected at OC «Ukrainian technological products», External economic association "Novosvit", OC "Energoinvest". Use area - electric power industry.
