Abstract

The invention provides a power load prediction key factor identification method and system, and the method comprises the steps: obtaining environment variable data; performing normalization processing on the environment variable data according to a preset normalization rule to obtain an environment variable set; and inputting the environment variable set as an input quantity into a pre-trained related factor identification model to obtain a power load prediction key factor. The method has the capability of dynamically identifying the key related factors in different scenes according to the boundary data, so that the dynamic identification of the key related factors is realized, and the power load prediction accuracy is improved. And according to the external environment change, dynamically selecting a related factor which has the closest relationship with the power load, and taking the related factor as an input quantity of a related factor prediction algorithm, thereby realizing dynamic prediction analysis according to the external environment change.

Description

technical field [0001] The invention relates to the technical field of electric load forecasting, in particular to an identification method and system for key factors of electric load forecasting. Background technique [0002] Power load forecasting is an important basis for power grid dispatch optimization, and has a direct impact on operations such as operation mode arrangement and generation plan preparation. In recent years, with the continuous deepening of power market reform, market members have been paying more and more attention to the rationality of power grid dispatching and operation planning, and power load forecasting is the focus of attention. [0003] Among the traditional power load forecasting methods, forecasting methods based on weather forecasting and other related factors are important methods for power load forecasting. Temperature, wind, sunshine, precipitation and other meteorological factors, holiday factors, economic factors, etc. will all have an ...
