Automation of Calculations in the Design of an Integrated Energy System Based on its Digital Twin

The construction of integrated energy systems (IES) based on traditional energy systems that operate separately ensures higher efficiency and reliability of energy supply to consumers. IES are complex objects for design. The digital twin is a tool that allows one to integrate all the tools necessary for design in a single information space. Software tools that implement the digital twin of IES and are developed for their design require high flexibility in organizing calculations, which is due to the need to simulate a variety of equipment and involve a wide set of methods and mathematical models. Automating the construction of the computing subsystem is an effective solution to overcome the above difficulties. The article proposes a methodological approach to automating the construction of the computing subsystem of the digital twin of the IES. In accordance with the proposed approach, automated construction is performed on the basis of a software platform using modern metaprogramming tools. When building, the concept of Model-Driven Engineering is implemented and knowledge formalized in the form of ontologies is used. The article outlines the components of the proposed methodological approach to automating the construction of the computing subsystem of the digital twin of the IES, which include the following: principles of software platform development; software platform architecture; technique for automated construction of the digital twin computing subsystem; principles for ensuring the universality of software components. The digital twin obtained as a result of the practical application of the proposed methodological approach makes it possible to carry out computer and mathematical modeling of the IES in the virtual space, exploring various configurations of its construction. The implementation of modeling within the framework of the digital twin of IES makes it possible to implement flexible and efficient approaches to solving the problems of designing IES and to obtain design recommendations that can be implemented when building real IES.
