“…Considering a set of tasks of control of integrated energy systems, it is advisable to divide these tasks into two groups: expansion planning of intelligent integrated energy systems and their operation control. As the analysis of the literature carried out in [4,8] shows, the main attention of the authors is concentrated on the tasks of operation control, while the calculation of the flow distribution and its optimization in the integrated energy system is considered as the basic task. On this basis, other tasks of operation control of the integrated energy system are formulated and solved, in particular, at the optimization of daily operating conditions at their dispatching, the analysis of the reliability of energy supply, etc.…”

“…In [14], the task of joint expansion planning of electric and gas transmission networks with endogenously given market gas prices, taking into account their volatility due to network restrictions, is considered. In [15], an innovative architecture of an intelligent integrated energy system and its control system is proposed based on the principles of a cellular structure, symmetric (multidirectional) energy flows, automatic reconfiguration of the network in emergency conditions, network-centric concept of control and self-regulation, etc. Summing up, it should be noted that the methodology and tasks of expansion planning of integrated energy systems have been worked out significantly less compared to the methodology and tasks of their operation control.…”

Active promotion of digital technologies in the energy sector requires a change in the principles of building energy systems, as well as the concept of their expansion planning. The functioning of infrastructural energy systems that are transforming as a result of the innovative development is fundamentally impossible without advanced information and communication technologies and intelligent digital tools. Energy systems are becoming sophisticated cyber-physical systems. At the same time, the problems of cybersecurity are exacerbating. The joint functioning of several types of energy systems in the form of a single integrated energy system provides new functional capabilities. The use of digital technologies in integrated energy systems provides the collection, processing, transmission and representing of information on all components of the system regarding all aspects of integration. Digitalization of integrated energy systems is carried out in the following two directions: application of digital technologies for individual subsystems for the purpose of their control; the use of digital technologies for technical and technological integration solutions in order to ensure coordination of subsystems and the implementation of system-wide goals. The adoption of digital technologies in integrated energy systems contributes to the organization of flexible, coordinated control of the expansion planning of such systems.

“…The integration of many separate systems into a single technological complex ensures the implementation of new functional capabilities, the use of more advanced technologies in operation, and the construction of integrated systems with coordinated control of their operation, as well as active participation of the consumer in the energy supply process [1][2][3][4][5]. In such energy systems, the end user is considered as a partner of energy entities in terms of ensuring reliable operation of the energy system, acquires the status of an active one and becomes one of the main elements in the energy system [6].…”

Modern cities and industrial centers boast a developed energy infrastructure including fuel, electric, heating, and cooling systems. The integration of many separate system into a single technological complex can provide new functional capabilities, the application of more advanced technologies for operation, and the establishment of integrated energy systems. Such systems have a multidimensional structure of functional features and properties of development. The control of integrated energy systems with load-controlled consumers represents an urgent and a rather challenging task. The paper is concerned with an approach to short-term control of integrated energy systems with load-controlled consumers. Planning the daily electricity and heat loads is performed for an integrated energy system, including energy storage systems and electric water heaters, electrical shiftable loads of individual consumers as well as power generation by additional electricity and heat sources (PV systems, wind turbines, heat pumps). The optimal daily profiles are obtained based on the initial profiles of electricity and heat loads, photovoltaic generation and optimal profiles of using electricity and heat storage systems and shiftable load. Optimal daily electricity and heat load profiles differ greatly from the initial ones, which provides a reduction in the energy costs for the consumer.

The research of prosumer energy supply systems is faced with the following problems [6][7][8][9]: finding of optimal mix of prosumer self-generating equipment [10][11][12][13][14][15] and its corresponding operational costs and finding of optimal design of prosumer energy supply system by determine the equipment configuration [16-18] and its corresponding total costs. The important condition of both problems is meeting the thermal and electrical prosumer demand.…”

The conversion of existing energy systems to intelligent integrated energy systems can happen only if economic benefits due to introduction of the intelligent integrated energy systems will exceed required level of investments. Thus, it is necessary for every optimal design energy systems problem according to the purposes of the study to determine various aspects of equipment configuration, investment and a proposed unit commitment on a case-by-case basis. The studies, taking under consideration energy efficiency of renewable energy units, are particularly important as environmental safety standards are increasing. In the paper optimal design of prosumer energy supply system problem in the intelligent integrated energy system was investigated. For this purpose a super structure for an energy supply system includes different generating capacities with relevant power range. The superstructure for prosumer energy supply system consists of an electric boiler, a gas-fired boiler, a solar photo-voltaic, a solar heating system and a gas-fired CHP. An ability of district energy system to receive the excess generating energy is restricted by the constraints. The heat and electricity tariffs and the received to district energy supply system energy constraints are varying according to time period. As a result of this study, cost-effectiveness analysis of chosen equipment configuration was undertaken.
