Key Points

To establish a coordinated, multi-timescale low-carbon economic dispatch framework for integrated energy systems that resolves symmetric uncertainties from renewable generation and multi-energy loads.
Structured a hierarchical progressive optimization scheme across day-ahead (hourly resolution), intra-day (15-minute intervals), and real-time (5-minute resolution) stages.
Integrated multi-energy flow coupling, demand response mechanisms, combined heat and power units, energy storage, and power-to-gas technology.
Intra-day rolling correction increased combined heat and power generation by 40.70% and waste-heat cooling by 41.12%, while real-time storage maintained electricity, heat, and cooling load deviations at 0.17%, 0.10%, and 0.06%.
Power-to-gas deployment lowered gas procurement costs by 12.70% and decreased net carbon emissions from 5.14 t to 4.91 t.
Demand response mechanisms cut electricity purchasing costs by 9.97%, reduced evening peak electric vehicle charging loads by 8.32%, and lowered EV charging costs by 15%.
