Abstract
Purpose. To investigate and monitor the state of the integrated energy systems with energy hubs and distributed generation sources one must formalize the main operation modes of the mentioned systems. These modes may be not only technical but may also be economic. Methodology. In order to achieve the purpose of our investigation we have analyzed the main features of aggregation of diverse sources of distributed generation (e.g. solar, wind, small hydro power plants etc.) into the energy hubs dividing them by the type of the converters used with each type of the renewable energy sources and non-renewable sources of distributed generation. This allowed to analyze their influence on the improvement of the quality of electricity supply of consumers which was considered in this paper. Based on the analysis of the energy characteristics of different energy sources in the energy hubs as well as on the types of converters used with these sources which we performed, we determined and formalized the most common modes of operation of power generation sources in the energy hubs. In addition to the performed analyses of the generation types in integrated energy systems we also analyzed main structural components of aforementioned systems. As energy transformation process is one of the most important processes for the analyses in energy systems with distributed generation we gave the characteristic of the transformation system based on the of power electronics devices types which are most commonly used. Results. We determined the most common two types of modes of functioning of power systems with energy hubs based on the nature of interaction with consumers and the general electricity network. In the course of the analysis, we determined the commercial and technical modes of functioning of power systems with energy hubs, as well as conditions of their flow which we presented in this paper.
