Modeling and Multi-Stage Planning of Cement-IIES Considering Carbon-Green Certificate Trading

The cement industry is an important industrial entity responsible for implementing carbon emission reduction targets. Considering the trading and green certificate mechanisms, this paper presents a multi-stage planning approach constructed Cement-Industrial Integrated Energy System (Cement-IIES). Carbon technologies represented by low-temperature waste heat recovery, as well phased changes in economic technical parameters, are considered model. case study shows that proposed method not only optimizes design economy of Cement-IIES but also achieves substantial production process energy supply system. Compared with traditional single-stage planning, improves system’s efficiency 13.88% flexibly adapts to policies such “coal reform”, quotas. recovery technology helps system utilization two stages increase 0.45% 0.86%, respectively, whilst oxygen-enriched combustion capture can reduce total emissions about 83%. In addition, negative effect biomass gives access annual benefits CNY 3.10 × 107 7.89 stages, respectively.
