Abstract.
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.
1 Introduction 
Modern cities and industrial centers have a developed 
energy infrastructure, including fuel, electricity, heat and 
cool supply systems. These systems have a certain 
functional independence and can interact with each other 
in normal and emergency conditions, as well as at the 
level of interchangeability of primary energy resources 
and the use of energy carriers. All this shows their 
natural integration, which is even more intensified as the 
formation and development of intellectual, information, 
telecommunication systems. Jointly they present a new 
structure that is integrated energy systems. This structure 
combines a certain independence of the systems with 
their coordinated participation in solving the main 
problem related to ensuring of social and economic 
activity. The quality of its solution is ensured by the use 
of digital technologies. Control of digital integrated 
energy systems is an urgent and complex problem.
