Embodiment Construction

[0100] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings. It should be noted that this embodiment is descriptive, not restrictive, and cannot thereby limit the protection scope of the present invention.

[0101] The interaction relationship between ICES operators and residential building users is as follows: figure 1 As shown, ICES operators are located in the upper layer, and residential building users are located in the lower layer. There is interaction between ICES operators and users, and the decisions of the two influence each other. The red, green and black symbols in the figure represent optimization variables, dependent variables and fixed parameters, respectively. Among them, the dependent variable is the electric power (P chp ) and thermal power (H chp ) and the thermal power generated by the heat ...

Abstract

The invention discloses a community integrated energy system double-layer optimization method considering heat supply demands of residential users, which comprises the steps of integrating a community integrated energy system double-layer optimization model of the residential users and solving a double-layer optimization scheduling problem. A community integrated energy system double-layer optimization model integrating residential users is constructed on two layers of a supply side and a demand side. Wherein the upper layer comprises an ICES operator model, a central heating network model and a power distribution network model which are coupled with a superior energy system and energy equipment such as a combined heat and power (CHP) unit, a heat pump and the like; and the lower layer comprises a thermal load model considering the heat storage characteristics of the residential building users. According to the method, the heat storage characteristic of the residential building is effectively combined, the personalized heating characteristic of the user is considered, the heat demand response adjustment of the residential building user is stimulated in the centralized heating mode, and the more economical utilization effect of heat energy is achieved.

Description

technical field [0001] The invention relates to the technical field of optimal allocation of heating energy, in particular to a double-layer optimization method for a community comprehensive energy system considering the heating demand of residential users. Background technique [0002] With the continuous development of society and economy, the energy demand of human beings continues to grow. Among them, the energy consumption of end-use energy units represented by buildings is on the rise. The 2020 "China Building Energy Conservation Annual Development Research Report" shows that the total energy consumption of buildings in my country accounts for about 23% of the total energy consumption of the whole society. At the same time, with the continuous improvement of my country's urbanization level and the adjustment of industrial structure, the proportion will continue to grow. Among them, the heating energy consumption of buildings occupies a large proportion of the total fi...
