Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0056] see figure 1 , is a flow chart of the steps of an embodiment of the meteorological factors-based grid power load forecasting method provided by the present invention.

[0057] In this embodiment, the described grid power load forecasting method based on meteorological factors mainly includes the following steps:

[0058] Step S1: Analyze the correlation between meteorological factors and grid power load.

[0059] In order to find out the meteorological factors related to the power load of the power grid, it is necessary to conduct a correlation analysis based on a large number of meteorological data and load data.

[0060] In a practicable manner, the step S1, that is, analyzing the correlation between the meteorological factors and the power load of the power grid, i...

Abstract

The invention discloses a meteorological-factor-based grid power load prediction method. The method comprises: correlation between a meteorological factor and a grid power load is analyzed; air conditioner load data over the years that are correlated with the meteorological factor in a sample region are collected; statistics of a natural growth rate of an air conditioner load is carried out; according to the air conditioner load data over the years as well as the natural growth rate, an air conditioner load of the current year is obtained; the air conditioner load of the current year and a basic load of the current layer are superposed to obtain a largest scheduled grid power load of the current layer. In addition, the invention also provides a meteorological-factor-based grid power load prediction system; With combination of correlation of the meteorological factor and the grid power load, accuracy of grid power load prediction is improved.

Description

technical field [0001] The present invention relates to the technical field of grid power forecasting, in particular to a grid power load forecasting method and system based on meteorological factors. Background technique [0002] Grid power load forecasting is not only the basis for carrying out important work such as power market analysis and grid planning project evaluation, but its power balance results are also an important reference for decision-making of major power supply capacity space and external power inflow planning capacity. However, the current predictive analysis methods for the annual dispatching load are limited to the time trend method, T max The law (maximum utilization hours), etc., does not take into account the impact of climate or meteorological factors on the load, that is, the proportion of air-conditioning load. Due to various factors such as the acceleration of urbanization in my country, the transformation of the power grid that released the rig...
