How to calculate the gas storage for peak shaving?
Reply #22009-04-09
(1) Monthly unevenness coefficient and monthly peak coefficient: The unevenness coefficient for gas consumption by urban residents in China is generally between 0.90 and 1.30. Due to geographical location and climate conditions, the monthly peak coefficient for gas consumption is higher in cities in the south, while it is lower in cities in the north. (2) Daily unevenness coefficient and daily peak coefficient: Within a month or a week, the daily fluctuations in residential gas consumption depend mainly on residents’ living habits and work schedules. According to investigations, the daily unevenness coefficient in ordinary cities in our country ranges from 0.835 to 1.182. Based on the experience of gas supply in most cities, the daily peak coefficient is generally 1.15. The unevenness coefficients and peak coefficients show that the hourly variation in gas consumption among urban residents and commercial users is significant, with the highest levels occurring at night, followed by noon, and then in the morning. The hourly unevenness coefficient in general cities ranges from 0.2 to 3.2

What is the peak coefficient for days, months, and hours in the Xinjiang region? When calculating the daily gas storage capacity, it is necessary to use the specific data for each hour. An example is given in the third edition of \"Gas Transmission and Distribution\". Could someone provide the hourly gas consumption data for the cities in Xinjiang that use natural gas? Thank you
