基于PLS的湖南省电力消费影响因素分析

Empirical Analysis of Impact Factors of Electricity Power Consumption in Hunan Province Based on PLS

运用现代多元统计技术——偏最小二乘回归PLS,在各影响因素存在多重共线性和样本数据短缺条件下进行了定量分析。本文不仅给出各影响因素对湖南电力消费的重要度指标图,而且确定这些影响因素与湖南电力消费需求之间的定量关系,为湖南电力市场分析提供了理论依据。

Applying modern statistical technology-Partial Least-Squares （PLS） regression, and quantity analyzing the relationship of Electricity power consumption on the condition of multi-collinearity between multivariable and small sample, the paper not only put forward the graph of variable importance projection about every factor relative to electricity power consumption, but also found the quantity relation of impact factors relative to power consumption, and set the frame of reference for electrical market analysis in Hunan Province.
