| Abstract Scope |
Growing market competition is compelling steel enterprises to prioritize cost control. Byproduct gas, constituting approximately 40% of their total energy consumption, is a key area for potential savings. However, current extensive management practices necessitate refined scheduling to achieve cost reductions and efficiency gains. Typical optimization models aim to balance gas holder level stability against power generation revenue. Effective scheduling requires maintaining levels near preset references to preserve buffering capacity, while also allowing significant fluctuations to capitalize on time-of-use electricity prices through multi-period scheduling. Conventional penalty functions, employing fixed reference levels and penalty factors, create an irreconcilable conflict between stabilizing levels and maximizing revenue. Based on the actual equipment conditions of the steel enterprise, this study develops time-variant control strategies and objective functions, enhancing the scheduling model’s responsiveness to time-of-use electricity pricing and ultimately achieving greater energy cost savings. |
