摘　　要：负荷特性分析对电力企业经营规划具有重要的理论指导作用与实践应用价值,对同一地区与居民生活密切相关的商业负荷和居民住宅负荷,从各个角度进行了对比分析。首先,从最大负荷变化及负荷特性指标入手,阐述了两者的年度和月度负荷变化规律,进一步利用基准负荷比较法求取了典型月的日最大降温负荷及最高占比;其次,利用散点分布和最小绝对残差法得到的拟合曲线,从出现时刻角度分析了日最大负荷的特点,并研究了典型日负荷变化;最后,借助斯皮尔曼相关系数法进行了相关性分析,运用最小二乘法构建的回归模型研究了气温敏感性,同时深入挖掘了南北方小区的负荷特性异同。分析结果表明,加强电力需求侧管理,优化配电网负荷特性具有重要意义。Load characteristic analysis has important theoretical guidance effect and practical application value for the power enterprise’s management planning.Since the close correlation with residents living,the commercial and residential load of the same region were analyzed contrastively from various angles in this paper.Firstly,starting from the maximum load variation and the load characteristic indexes,the annual and monthly load variation of commercial and residential areas were expounded,and the daily maximum cooling load and the highest percentage of typical month were calculated by the base load comparison method.Secondly,using the scatter distribution and the fitting curve by minimal absolute residual method,the characteristics of the daily maximum load were analyzed from the view of a moment,and the variation of typical daily load was also researched.Finally,the correlation analysis was done through the spearman correlation coefficient method,and the temperature sensitivity analysis was studied by the regression model which is used the least square method.At the same time,the similarities and differences of residential load were digged deeply in the north and the south area.The analysis results show that strengthening electric power demand side management and optimizing distribution network load characteristic have great significance.
