Abstract
Features of development of electric power industry of Ukraine from the point of view of the formation of the perspective structure of generating capacities of UES of Ukraine and development of renewable energy sources (RES) are characterized. In the analysis of the problem of introduction of RES in the energy system of our country and the use of advanced tariff systems, three levels are identified: the highest level - the UES of Ukraine; middle level – regional energy companies; lower-level - local energy supply systems. It is shown that the study of choosing a strategy for better implementation of dynamic electricity prices, as well as trends in business models for local electricity markets with a combination of physical, communication, information, and business levels are relevant. The peculiarities of Microgrid development as a basic element of the functioning of local electricity markets under the condition of formation of optimal modes of generation and consumption of electricity using dynamic charging, which can provide a significant part of imbalance compensation due to the widespread introduction of RES. The article considers the formation of dynamic prices at the level of local power systems (Microgrid), which have features of both the operation and implementation of business models. The elements of the business model for the local electricity market, which is proposed for the sole owner of all generators and consumers, are analyzed when Microgrid is considered as an independent element of the local market, where a dynamic balance between supply and demand. It is determined that at the level of local energy supply systems charging must be based on dynamic models that will take into account the dynamic nature of generation and regulation of electricity consumption in the system and stimulate appropriate desired actions by the consumer. It is proposed to use the tariff calculation not for the time interval, but for the state, as well as to control the optimal levels of generation and consumption of electricity to use the reference tariff and the formation of reference profiles of generation and consumption of electricity. Modified Frieze reactive power was used to estimate the discrepancy between current and optimal power regimes. References 37, table 1.
