reliability of energy supply, etc. The group of tasks 
under consideration is solved taking into account the 
various components of the integrated energy system: 
electricity and heat supply systems; electricity, water, 
and gas supply systems; electricity and gas supply 
systems; electricity, heat and cool supply systems; etc. 
Research has been carried out to analyze integrated 
energy systems taking into account the activity of 
consumers in control of their energy consumption, the 
use of energy storage devices, modern information and 
communication technologies, etc. [9, 10]. Mainly, 
network models of flow distribution are used, including 
with the integration of models of interconnected energy 
systems into a common model [8]. A fractal approach to 
modeling large integrated electric-thermal networks is 
considered in [11]. A simulation model of an integrated 
energy system based on the concept of an energy hub is 
proposed in [12]. To optimize operation, both classical 
methods of mathematical programming and evolutionary 
algorithms are used. 
With regard to the methodology and tasks of expansion 
planning of integrated energy systems, it is advisable to 
pay attention primarily to the review [13]. This review 
examines the problem of sustainable urban development 
based on the integration of energy supply systems. In 
general, this work reflects the interpretation of the 
traditional methodology for expansion planning of 
energy systems, taking into account the multicriteria 
nature of tasks under various scenarios of external 
conditions with the optimization of target indicators of 
the efficiency of expansion planning of integrated energy 
supply systems, reducing harmful emissions and 
encouraging the use of renewable energy resources. 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.
