Design of integrated energy systems based on their digital twins

Design of integrated energy system (IES) is a complex problem, which is caused by the complex network configuration of these systems, a wide range of used equipment and mathematical models of IES subsystems. The digital twin allows one to model in virtual space various configurations of IES and to obtain the optimal variant of construction of the system under study. The paper proposes the principles of digital twin for design of IES. The authors present a methodological approach to the design of IES on the basis of its digital twin. The results of modelling of the energy supply system obtained on the software implementation of the components of the digital twin of the IES are presented.
