Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] An energy system optimization method based on the integrated energy model of comprehensive hubs. This method first obtains the connection relationship between each integrated hub and the transmission system, establishes an integrated energy model, and then sets the objective function according to actual needs. According to the objective function and The above-mentioned integrated energy model optimizes the energy system, and obtains the optimal input and output of each energy carrier subsystem under the condition of satisfying the objective function.

[0026] In the present invention, the basic model of the comprehensive hub is as figure 1 shown. A comprehensive hub is defined as a basic unit with energy activities, product manufacturing, and waste discharge treatment, which can be as small as an enterprise or building, or as large as...

Abstract

The invention relates to an energy system optimization method based on a comprehensive hub integrated energy model. The method comprises the steps that firstly, comprehensive hubs and connecting relations between the comprehensive hubs and a transmission system are acquired, the integrated energy model is built, then an object function is set according to actual needs, an energy system is optimized according to the object function and the integrated energy model, and optimal input and output of all energy carrier subsystems are obtained under the condition of meeting the object function. Compared with the prior art, the comprehensive hubs are used as basis units for building the model by the built integrated energy model, the model is modularized obviously, and the model building process is simple and flexible.

Description

technical field [0001] The invention relates to an energy system optimization method, in particular to an energy system optimization method based on a comprehensive hub integrated energy model. Background technique [0002] Since the early 1970s, with the issue of energy supply security being highly valued by oil-importing countries, a series of energy models for analyzing and studying various energy systems and their subsystems have been born. With the gradual promotion and in-depth application of energy models in the social and economic fields, energy models have become an important means of energy supply and demand forecasting, energy system planning, and energy and environmental policy formulation. Based on the different characteristics of energy problems, many types of energy models have been proposed one after another. From the perspective of modeling methods, existing energy models are divided into bottom-up model, top-down model and hybrid model. The bottom-up ener...
