Dongfang Electric Corporation · Heat-supply algorithms · Sep 2025 – Dec 2026 (Expected)
Heat-balance and physically constrained fuel models with two-stage optimization for heat-load allocation across CHP units.
- Standardized operators
- 5
- Model-predicted fuel reduction
- 0.2952–0.4719 t/h
- Optimization method
- HiGHS + SLSQP
Background
Optimized coordinated heat supply across CHP units with different fuel-use characteristics and heating capacities, subject to power and heat demand and operating limits.
Methods
- Processed more than 300 DCS measurement points, including data cleaning, time alignment and feature extraction.
- Combined heat-balance principles with physically constrained regression, then used HiGHS and SLSQP in a two-stage heat-allocation optimization.
- Packaged the calculations into five standardized operators and participated in platform deployment and testing.
Results
- The two unit-type fuel-consumption models achieved R² values of 0.9588 and 0.9717.
- Representative cases showed model-predicted standard-coal consumption reductions of 0.2952–0.4719 t/h.
Project outputs
Completed platform deployment and testing of the five operators and filed one invention patent application.
