Short-term building energy consumption interval prediction method, system, medium and device

Abstract

The invention provides a short-term building energy consumption interval prediction method, system, medium and device, and the method comprises the steps: selecting a building position and a prediction time period which need to be subjected to short-term energy consumption prediction, obtaining the weather condition of the prediction time period, and obtaining a time schedule of a user using a building; acquiring energy consumption data, weather conditions and building use duration as sample data; obtaining the building area, obtaining the local average outdoor air temperature within the heating time, calculating the indoor and outdoor air temperatures, obtaining the illumination model and power in the building, and calculating the building energy saving rate in the corresponding time period; the method comprises the steps of obtaining energy consumption prediction data of an expected time period, calculating a variance value of historical data of the prediction time period, and determining a prediction value estimation interval under the condition of a given confidence level by utilizing the variance and the building energy saving rate. The estimation interval of the short-time building energy consumption prediction value is further given through building energy saving rate and variance estimation while the energy consumption prediction value of the building is predicted by the support vector machine.

Description

technical field [0001] The present disclosure relates to the field of energy consumption estimation, in particular to a short-term building energy consumption interval prediction method, system, medium and equipment. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the continuous improvement of people's lives, people have put forward higher requirements for building functions and indoor environment, and the problem of energy consumption has become increasingly prominent. The proportion of building energy consumption in the total energy consumption of the society is increasing continuously, among which the energy consumption of public buildings accounts for a large part, and the electricity consumption of public buildings accounts for more than 30% of the electricity consumption of social buildings, while the construction of large publ...
