Problems solved by technology

[0002] In the existing technology, for different enterprise objects, the expected power load model for a certain period of time in the future is usually unified, but in fact, due to the significant correlation between the power load of different enterprises and different factors and different factors For example, the electricity consumption of weather-sensitive enterprises is usually very related to weather factors, while the electricity consumption of other types of enterprises may not be related to weather factors at all. Therefore, the prediction accuracy obtained cannot be effectively guaranteed

Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0029] The methods discussed below, some of which are illustrated by flowcharts, can be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof. When implemented in softwa...

Abstract

The invention provides an electricity load prediction method and device. The method includes on the basis of acquired historical electricity data and multidimensional factor historical data relevant to the electricity, determining the type of the object of the electricity load to be predicted; during the prediction period of the given electricity load, determining the type of the period to be predicted; determining the type of special historical samples corresponding to the object and period type; determining the kernel function of a multi-resolution support vector machine prediction model to trained corresponding to the type of the object; training the corresponded multi-resolution support vector machine prediction model; inputting the data of the acquired special historical samples with the same type in the special period into the multi-resolution support vector machine prediction model, and predicting the electricity load of the object in the period to be predicted. Thus, the prediction accuracy of the electricity load of an enterprise in a short period in future can be improved effectively.

Description

technical field [0001] The invention relates to the field of electricity consumption, in particular to a method and device for predicting electricity load. Background technique [0002] In the existing technology, for different enterprise objects, the expected power load model for a certain period of time in the future is usually unified, but in fact, due to the significant correlation between the power load of different enterprises and different factors and different factors For example, the electricity consumption of weather-sensitive enterprises is usually very related to weather factors, while the electricity consumption of other types of enterprises may not be related to weather factors at all. Therefore, the prediction accuracy obtained cannot be effectively guaranteed. Contents of the invention [0003] One of the purposes of the present invention is to effectively improve the accuracy of forecasting the electricity loads of different enterprises in the short term ...
