Abstract As the surplus of gas and the demand of steam and electricity are different under different operating conditions，the gas-steam-electricity system operation need to optimize accordingly in steel plants. To minimize the energy cost of system operation，the coupling optimization scheduling model of the gas-steam-electricity system was established under different production loads in iron and steel enterprises，based on linear programming. As the scheduling interval in the model was 5 min，with the model the real time optimal production scheduling of gas，steam and electricity under different working conditions can be obtained. By using the actual production data of S steel plant for case analysis，the optimized scheduling scheme was calculated to achieve optimal allocation of gas-steam-electricity system，and the energy cost was reduced. The validity of the model was verified.

Key words： iron and steel enterprise energy medium linear programming optimal scheduling
