Abstract: Factors such as ambient temperature, festivals and holidays will remarkably influence on gas consumption of Beijing City, especially during heating period in winter season, disequilibrium in gas consumption is a big problem.Aiming at the characteristics in technological actualities, gas supply and marketing of Shanxi-Beijing Gas Transmission Pipeline System, winter peak shaving method with gas storage in end pipe-section combined with underground gas storage is adopted.Under the condition of limited peak shaving capacity with the end pipe-section method, optimization on peak shaving method for Dagang Underground Gas Storage is carried out, which effectively solves the problem of winter gas consumption and peak shaving in Beijing City, Tianjin City and Hebei Province.
