Problems solved by technology

[0003]Multi-energy complementary integrated energy system (Integrated energy system, IES) has a wide variety of equipment and complex structures. Different application scenarios and environments have large differences in cooling, heating, and electrical loads. At the same time The inherent volatility and uncertainty of new energy make the operating mode of the system changeable, the coupling relationship between equipment capacity and operating mode is further deepened, and the optimization design is extremely difficult
[0004]Currently, in actual integrated energy projects, on the one hand, it is very difficult to collect building load data, especially for new parks, where there is no historical load data for reference; on the other hand, it is difficult for designers, The personal experience of engineers is highly dependent, subjectivity is strong, reliability is low, and there is no scientific and standardized planning and design platform
Although there are many design methods for integrated energy systems, there is no planning and design method that integrates building load, system structure, equipment capacity, and operation mode, and it is difficult to obtain the optimal solution.
[0005]For example, the comprehensive energy system planning and design method proposed in the patent "A Planning and Design Method for Regional Comprehensive Energy System" adopts the chain design idea of ​​system scheme and operation strategy, There is no parameter feedback between the two, so it is difficult to obtain the optimal performance, and this case uses a single typical daily load data to plan the system capacity, which can easily lead to the mismatch between supply and demand in practical applications
