| Abstract |
In order to study the development and application of digital twin technology in the integrated regional energy system of smart cities, this paper proposes a basic concept of digital twin, and gives the construction method and possible applications of the energy internet digital twin. Taking the energy internet plan as an example, the key problems solved by digital twin technology are detailed. Finally, CloudIEPS, an energy internet planning plat-form based on digital twin, is introduced, which further proves the important role of digital twin technology through energy internet planning cases. According to the case analysis, the one-time investment cost of the optimized solution is 3,231,400 yuan less than the original solution, and the annual operating cost increases by 217,000 yuan. Compared with the original scheme, the one-time investment cost of the optimized scheme is reduced by 3,231,400 yuan, and the annual operating cost is increased by 217,000 yuan. The average heat loss rate of the original scheme is 11.5% and the average cooling loss rate is 12.4%, while the average overheating rate of the optimized scheme is only 1.9% and the average cooling loss rate is 10.4%. |
