Electricity sale quantity distribution method and device

Abstract

The invention discloses an electricity sale quantity distribution method and device. The electricity sale quantity distribution method includes: for each electricity sale object, correcting an electricity sale quantity predicted value of the electricity sale object in a next operating cycle according to the electricity sale quantity predicted value of the electricity sale object in the current operating cycle; after determining a distribution weight of each electricity sale object according to the corrected electricity sale quantity predicted value of the electricity sale object in the next operating cycle, distributing the electricity sale quantity of the next operating cycle according to the total electricity sale quantity and the distribution weight of each electricity sale object, wherein the sum of the electricity sale quantity predicted values of the sub operating cycles of the electricity sale object in the operating cycle is the electricity sale quantity predicted value of the electricity sale object in the operating cycle, and the electricity sale quantity predicted value of the electricity sale object in the sub operating cycle of the operating cycle is determined according to the electricity sale quantity actual values of the corresponding sub operating cycles of a plurality of operating cycles before the operating cycle. The electricity sale quantity distribution method and device enable the electricity sale quantity to be distributed more reasonably.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and device for distributing electricity sales. Background technique [0002] Power grid electricity sales forecasting is a basic task in the electricity market. Correctly predicting the level of regional electricity sales can provide decision support for power supply companies, and it can guide the rational operation of power plants and transmission and distribution networks, and promote the development and development of electricity markets. Construction is of great significance. [0003] When electricity sales companies allocate electricity sales, relevant technical personnel can use the historical data in the database to determine the total electricity sales in the next business cycle through mathematical analysis, and then allocate the total electricity sales based on the established analysis and decision-making model. To each electricity sales object, that ...

However, the inventors of the present invention have found that some existing weight calculation methods, such as AHP (Analytic Hierarchy Process), neural network, principal component analysis, gray evaluation, etc., are suitable for what-if models in some cases Weight calculation, but it is not applicable to the distribution calculation of electricity sales. The reason is that these weight calculation methods need to manually judge the electricity sales capacity of the electricity sales object based on experience in the process of distribution of electricity sales, so as to set the weight calculation. The elements of the judgment matrix lead to more human-subjective factors involved in these weight calculation methods, which easily lead to large weight calculation errors, which in turn cause unreasonable distribution of electricity sales and consume manpower; moreover, these weight calculation methods are performed using the judgment matrix. The process of weight calculation involves multiple iterative calculations of the matrix. During the calculation process, data enlargement, reduction, and decimal point removal operations will further increase the weight calculation error caused by human subjective factors, and increase the cost of electricity sales distribution. unreasonable

The performance of unreasonable distribution of electricity sales is as follows: the electricity sales allocated to some electricity sales objects exceed the electricity sales capacity of these electricity sales objects, or the electricity sales allocated to some electricity sales objects cannot meet the electricity consumption of these electricity sales objects Quantity demand etc.
