Embodiment Construction

[0037] Such as figure 1 Shown is the method flow chart of the method of the present invention: the electric load forecasting method applicable to multiple scenarios provided by the present invention includes the following steps:

[0038] S1. Select the area to be predicted; it can be divided into provinces, cities, counties, and districts to clarify the boundary and scope of measurement;

[0039] S2. Obtain and sort the load forecast influencing factors in the area to be forecasted;

[0040] In the specific implementation, weather, environment, holidays and remaining factors can be used as load forecasting factors, and the least square method is used to calculate the size of each load forecasting factor and sort them;

[0041] The least square method is used to calculate and sort the size of each load forecasting influencing factor. Specifically, the following steps are used to calculate the size and sort:

[0042] A. Use the following formula as the load forecasting formula...

Abstract

The invention discloses a power load forecasting method suitable for multiple scenes, which comprises the following steps of: selecting a region to be forecasted; obtaining and sorting the influencingfactors of load forecasting in the region to be forecasted; acquiring historical data of influence factors of load forecasting in the area to be forecasted; selecting a load forecasting model of thearea to be forecasted; establishing a load forecasting model of the area to be forecasted; forecasting the electric load of the area to be forecasted. The method of the invention considers each influence factor which affects the electric power load forecasting, and builts load forecasting models in multiple scenes, so that the load forecasting method realizes load forecasting under the condition of multiple influencing factors, and simultaneously the method adopts different load forecasting models to forecast and combine multiple types of scenes, so that the method of the invention can more accurately and reliably forecast the future load, and the method of the invention is simple, reliable, scientific and practical.

Description

technical field [0001] The invention specifically relates to a power load forecasting method applicable to multiple scenarios. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. [0003] At present, the growth of power load has great uncertainty, which will affect the reasonable preparation of power grid operation plans and medium and long-term power grid planning plans by power grid companies, and will have a major impact on future reliable and economical power supply. In addition, there are currently many electricity sales companies in my country, and our country is also actively promoting technological and market innovation. At that time, the level of load forecasting will affect the quotation strategy and operating efficiency of major ...
