Optimisation of Production, Distribution and Supply of Electric Energy under the Conditions of the Energy Market of Ukraine

The article considers approaches to modelling production, distribution and supply of electric energy in the energy system of Ukraine under conditions of the energy market. It considers specific features of electric energy as a commodity and, as a consequence of these specific features, a disbalance between supply and consumption of electric energy. It justifies appearance of the task of co-ordination of volumes of production and supply with the established level of demand, subject to dynamic changes, under conditions of deficit of resources. It takes into account that electric energy is delivered to consumers through intermediary nodes - pumped-storage plants. The authors propose to reduce the task of finding an optimal plan of transmission of electric energy from points of production to points of consumption with minimisation of transportation expenditures to a multi-dimensional transportation task with intermediary nodes. The article formulates a mathematical model of this task, provides algorithms of its solution and considers a practical example of application of the proposed approach and provides analysis of the obtained results.
