Abstract
Based on the gas consumption data of Shang-hai from 2001 to 2003 and from 2020 to 2023,the variation patterns of unevenness factors of monthly,daily and hourly consumption were analyzed.The varia-tion pattern of unevenness factor of monthly gas con-sumption in Shanghai from 2020 to 2021 was basically consistent with that from 2020 to 2003.Gas consump-tion peaked in winter and reached its lowest point in summer,with the maximum unevenness factor of monthly consumption basically occurring in winter,fluctuating stably within the range of 1.22 to 1.38.The maximum unevenness factor of daily gas consumption from 2020 to 2021 significantly increased compared to that during 2001 to 2003.Conversely,the maximum unevenness from 2021 to 2023 significantly decreased compared to that in 2003.The unevenness factor of hourly consumption of urban gas users on peak days in Shanghai from 2021 to 2023 showed a high degree of consistency.The unevenness factor of hourly consump-tion of gas power plant users on peak days exhibited variations across different years.In contrast,the un-evenness factor of hourly consumption of large indus-trial users on peak days fluctuated slightly over time but remained within a narrow range of 0.95 to 1.05.关键词
