Embodiment Construction
[0054] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of this aspect will be further described in detail below in conjunction with the accompanying drawings.
[0055] Firstly, based on the development status and development potential of comprehensive energy systems at home and abroad, analyze the technical route for the available energy forms, and establish the development form and development scale according to the characteristics of the energy form, based on the differences in the system load capacity and energy resupply form. Three types of typical scenario models support the comparative evaluation and configuration optimization of comprehensive energy system models.
[0056] In step S1, three typical scenario models of external source, distributed, and potential integrated energy systems are established. The differences and comparisons are shown in Table 1.

Aiming at the problems of comprehensive energy system model comparison and optimization, the invention establishes a comprehensive energy system model comparison method and optimization system based on scene analysis. Based on supply and demand balance, a comprehensive energy system model comparison and quantification method is established according to a multi-objective criterion through equipmentcapacity limitation and energy structure boundary constraint conditions. Meanwhile, based on the operation situation analysis model, the economic benefit is used as an optimization target and an evaluation parameter, and the multi-grade heterogeneous energy flow supply amount is used as a variable, so that the supply and demand configuration planning optimization method for the energy model of the comprehensive energy system is constructed. And finally, the consistency of input data is controlled, model difference analysis and sensitivity analysis are carried out on a plurality of research objects, all information of optimized supply and demand configuration is obtained, and finally, an integrated energy system optimal configuration model is generated. According to the method, an objective and effective model comparison method, planning design and optimization transformation scheme can be provided for comprehensive energy system optimization planning.
