English
This study proposes an integrated electricity-heat-gas-hydrogen energy system for carbon anode industrial parks and develops a 24-hour multi-objective scheduling model. By using surplus PV power for hydrogen production and coordinating graded waste-heat recovery, the system achieves a 10.79% hydrogen blending ratio, reducing operating cost by 7.2% and carbon emissions by 2.3% compared to a non-hydrogen configuration, with further reductions of 27.9% and 26.0% versus a conventional system. Waste-heat utilization rate improves by about 30 percentage points.

📄 Abstract（原文）
Continuous carbon anode roasting in industrial parks requires a stable high-temperature heat supply and remains highly dependent on grid electricity and natural gas. However, existing energy-system studies rarely coordinate hydrogen production and storage, volumetric hydrogen blending, and temperature-graded waste-heat recovery under continuous production constraints. To address this gap, this study proposes an electricity–heat–gas–hydrogen integrated energy system for carbon anode industrial parks and develops a 24 h multi-objective scheduling model. The model coordinates heat demands at different temperature levels with hourly electricity and hydrogen flows, using surplus photovoltaic power to produce hydrogen for later high-load periods. The selected scheme achieves a daily volumetric hydrogen-blending ratio of 10.79%, with an operating cost of 82,985.75 CNY and carbon emissions of 54,371.53 kg. Relative to an otherwise equivalent non-hydrogen configuration, hydrogen coupling provides additional reductions of 7.2% in operating cost and 2.3% in carbon emissions. Compared with a basic conventional configuration, operating cost and carbon emissions decrease by 27.9% and 26.0%, respectively. Cascade recovery also increases the daily waste-heat utilization rate by approximately 30 percentage points. These results show that the proposed scheduling framework can coordinate hydrogen utilization and graded waste-heat recovery while maintaining continuous carbon anode production.
