摘要
利用2009—2023年广西91个国家级气象观测站的气温资料和广西社会用电量资料,运用Spearman相关分析法,研究近15a来广西气温和城乡居民用电量的变化趋势特征,以及运用度日数法探讨气温变化对城乡居民电力消费的影响。结果表明,广西气温整体呈上升趋势,各个季节的气温指标变化趋势不一;城乡居民电力消费增加,气象电量与气温要素的变化趋势基本一致。气温变化对广西城乡居民用电量的影响较大,以夏、秋季的影响最为明显;夏季增温导致居民电力消费需求明显增大,冬季低温过程增强也导致居民电力消费需求增加,秋季气温上升、低温过程强度减弱,居民电力消费需求有增有减;春季增暖则居民电力消费需求减少。
Using temperature data from 91 meteorological observation stations and social electricity consumption data from 2009 to 2023 in Guangxi,this study examines the trends in temperature,residents’electricity consumption and the influence of temperature fluctuations on electricity consumption.The results show that the overall temperature in Guangxi has shown an upward trend,with varying trends across different seasons.The residents'electricity consumption has increased,and the pattern of meteorological electricity demand closely follows changes in temperature-related factors.The temperature variation significantly impact Guangxi residents’electricity consumption,particularly during the summer and autumn seasons.Summer warming result in a notable increase in residential electricity demand,while the intensification of winter cold processes also boosts power consumption.In autumn,as temperatures rise and the intensity of cold processes weakens,electricity demand among residents fluctuates.Conversely,spring warming leads to a decrease in residential electricity consumption.
