摘要
如何平衡电力系统经济调度与低碳运行之间的矛盾并有效激发源-荷协同潜力,已成为当前电力系统优化领域的关键难题。为此,提出了一种考虑碳势-电价联合响应机制的源-荷协同低碳经济调度方法。分别阐述综合灵活运行方式下碳捕集电厂的低碳运行特性,以及需求响应的负荷调节原理,并分析二者在系统低碳运行方面的互补性,构建碳捕集电厂与需求响应的协同运行框架;通过碳排放流理论将部分碳责任分摊至负荷侧,提出碳势-电价联合响应模型,以提高负荷侧的降碳能力;以系统运行成本最小为目标,在阶梯碳交易机制的基础上,结合所提源-荷协同运行框架构建两阶段低碳经济调度模型,实现发电侧与负荷侧的协同优化;基于改进的IEEE 39节点系统的多场景对比分析表明,所提方法能够降低15%的系统碳排放,同时减少4%的综合运行成本,验证了所提方法在经济性与低碳性方面的协同优化效果。
Balancing economic scheduling and low-carbon operation in power systems while effectively leveraging the potential of source-load coordination is critical for current power system optimization.Then,a source-load coordinated low-carbon economic scheduling method considering carbon intensity-electricity price joint response mechanism was proposed.The low-carbon operational characteristics of carbon capture power plants under integrated flexible operation modes and the load regulation principles of demand response were elaborated.Additionally,their complementarity in lowcarbon operation was analyzed,and a coordinated operational framework for carbon capture power plants and demand response was established.By allocating partial carbon responsibility to the load side using carbon emission flow theory,a carbon intensity-electricity price joint response model was proposed to enhance the carbon reduction capability of the load side.With the goal of minimizing system operating cost,based on the tiered carbon trading mechanism and combined with the proposed source-load coordinated operation framework,a two-stage low-carbon economic scheduling model was developed to achieve coordinated source-load optimization.Comparative analysis of multiple scenarios based on a modified IEEE 39-bus system demonstrated that the proposed method could reduce system carbon emissions by 15%and decrease comprehensive operating costs by 4%,validating its coordinated optimization in both economic and low-carbon performance.
