Method and device for determining electric power planning scheme based on prosperity index index

Abstract

The invention provides a booming-index-based electric-planning-scheme determining method and an apparatus. The method comprises the following steps: obtaining sequence of the to-be-determined indexes, the sequence of the stationary reference indexes linked with the to-be-determined indexes, the maximum lag order and the maximum first order; establishing the relationship model between the sequence of the stationary reference indexes and the to-be-determined indexes; constructing an objective function; determining the coefficients of the relationship module; compressing the determined coefficients to obtain the variable corresponding to the coefficient compressed as zero; determining the first lagging of the sequence of to-be-determined indexes to the indexes corresponding to the sequence of the stationary reference indexes; and according to the first lagging, determining the electric-planning scheme. According to the invention, through the residual square sum of the relationship model and the MCP penalty terms of the relationship model, an objective function is constructed so as to further determine the coefficients of the relationship model with more precision. And therefore, the electric planning scheme becomes more economic through the use of the increased first lagging.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a method and device for determining an electric power planning scheme based on a prosperity index index. Background technique [0002] The economic prosperity index of the electric power industry, as an important index determined by the electric power planning scheme, is of great significance. The indicators for constructing the economic prosperity index usually use methods such as time difference correlation analysis to judge the leading and lagging properties of the indicators. The traditional methods for judging the leading lag of indicators include: time difference correlation analysis, K-L information method, benchmark cycle segmentation evaluation method, cluster analysis, peak-valley correspondence method, time series turning point method, scoring system method, etc. The general idea of ​​these methods is to compare the index sequence of different ...

Problems solved by technology

[0003] Due to the traditional method of determining the power planning scheme, when judging the leading lag of the indicators of the prosperity index, by comparing the similarity between the index sequences of different orders of lag and the index sequence of the reference cycle or the closeness of the peak and valley occurrence time points Therefore, its accuracy needs to be further improved, and the economy of its determined power planning scheme needs to be further improved
