[0001] The present invention relates to the field of energy system simulation, and in particular to an energy system visualization method. Background Art

[0002] At present, energy and environment have become the main bottlenecks restricting the sustainable development of the national economy. The trend has shifted from traditional extensive energy utilization to refined and decentralized sustainable low-carbon energy utilization. Therefore, the development of distributed low-carbon energy stations plays an important role in improving the overall efficiency of energy and the absorption capacity of renewable energy. The development of various energy conversion equipment (such as cogeneration, heat pumps, electric heating, electric hydrogen, etc.) provides a means for the coordination and complementarity of multiple types of energy. Distributed low-carbon energy stations, high-tech and equipment, are a new type of energy system that can achieve cascade utilization of energy and improve energy utilization. The development of distributed low-carbon energy stations can reduce environmental pollution, strengthen energy security, optimize energy structure, and improve energy utilization. Research on the joint optimization and regulation technology of distributed energy stations is a prerequisite for vigorously developing the efficient operation of distributed energy systems. It is also the technical basis for developing a demonstration project of low-carbon energy stations with electricity as the core and comprehensive energy optimization configuration on the demand side. It provides support for the transformation of energy configuration methods and the premise for promoting changes in production and life. It has become an important part of promoting energy transformation and the third industrial revolution.

[0003] However, in the prior art, in the early theoretical demonstration stage of establishing an energy system, virtual simulation is mostly performed in the form of software. The virtual energy system model established is not real and cannot intuitively reflect the dependency relationship between the energy system and the local building complex. Summary of the invention
