集成能源、物料、排放的能源系统建模与优化

考虑到多载体能源系统、生产系统、排放系统之间的复杂耦合关系,引入综合枢纽基本模型,提出了一种考虑能源、物料、排放协同作用的集成化能源系统建模方法.案例分析表明:能源成本及收益、产品生产对能源的需求量、产品收益以及废弃物排放成本等因素对能源系统的优化产生直接影响,这些因素之间协同作用,综合决定能源系统规划与设计的优化方案.所提出的建模方法相比多载体能源系统的描述,能够综合考虑能源、物料、排放之间的协同作用,更加系统地对能源优化问题给出合理的分析.

Modeling and Optimization of Integrated Energy System Considering Synergy among Energy, Material and Emission Elements

Considering the complex coupling relationship among multi carrier energy system, production system and emission system, a so called integrated hub concept was introduced, in terms of which a modeling approach for integrated energy system considering the synergy among energy, material and emission elements was presented. The case study indicates that the energy cost and benefit, the energy demand required by product manufacturing, the product benefit and emission cost directly influence the optimal results of energy system. These factors interact cooperatively to comprehensively decide the optimal strategy for energy planning and design. Thus due to the synergy among energy, material and emission the developed modeling approach could resolve the optimization problem of energy system much more systematically and reasonably as compared to the available multi carrier energy model.
