Problems solved by technology

At present, there is a lack of quantitative methods for building power demand elasticity, let alone systematic quantification methods. Under various thermal environment control ranges, there is no accurate mathematical description of the transmission process of building power demand elasticity, which also limits the demand response. successfully launch

Embodiment

[0073] The following will introduce the specific calculation process of each power elastic source in the building, and finally illustrate the example of the elastic aggregation of power demand in the whole building.

[0074] (1) Calculation example of thermal elasticity to electrical elasticity of thermal storage in buildings

[0075] The internal heat storage body of the building mainly includes the building maintenance structure and household equipment, facilities, etc. Because these heat storage bodies have a certain "thermal inertia", play a thermal buffering role, and can provide a certain degree of cold and heat load elasticity for the building, and ultimately This translates into electricity elasticity for air conditioning. The thermal elasticity of the thermal storage body is mainly related to the volume of the thermal storage body (including the surface area and thickness of the thermal storage body) and the properties of the thermal material (including the specific h...

Abstract

The invention relates to a rapid quantification method for building power demand elasticity based on building basic information, comprising the following steps: 1) respectively establishing a quantified sub-model of an internal heat storage volume, a quantified sub-model of electrical equipment and a quantified sub-model of an HVAC system; 2. ) According to each quantitative sub-model, the time intersection judgment and equipment load removal judgment are carried out, and finally the quantified value of the power demand elasticity of the whole building is obtained. Compared with the prior art, the present invention is beneficial to the smooth development of the power demand response project in my country, alleviates the problem of unbalanced supply and demand in the power grid in China, and at the same time, it can realize the maximum consumption of renewable energy in the power grid, and avoid "abandoning wind and abandoning light". phenomenon, and further increase the proportion of renewable energy in the grid.

Description

technical field [0001] The invention relates to the technical field of power demand response, in particular to a method for fast quantification of building power demand elasticity based on building basic information. Background technique [0002] Electricity is a form of energy that is difficult to store on a large scale. When there is a large gap between the power supply and demand of a city's power grid, one way is to cut off electricity directly through a relatively simple method, which will seriously affect the Production and life and user comfort. Another way is to reduce the peak power consumption or transfer it to the valley of power consumption by mining the elastic power consumption resources on the power demand side and through various power balance control methods, so as to maintain the balance of power supply and demand, which is called power demand response. Referred to as demand response (Demand Response, DR). [0003] Buildings are large consumers of electri...
