基于能源互联网理念,综合考虑电、热、冷互补共享的多能源系统优化规划是提高综合能源利用率的基础。多能源系统由多个分布式能源站供能,各能源站在具备自平衡能力的基础上通过供电网络和供热网络互联,实现横向多源互补。综合考虑能源配置的成本和典型场景系统网络运行的收益、碳排放量和一次能源消耗量,计及可行性约束和安全性约束,研究多能源系统优化规划数学模型。算例分析表明,兼顾典型场景运行的多能源系统规划方案达到了配置成本和运行综合效益最优的效果。
Based on the concept of energy Internet, the multi-energy system optimization programming considering complementarity and sharing of electricity, heat and cold is the basis to improve the multi-energy utilization. The multi-energy system is supplied by multiple distributed energy stations, which are connected by the power supply network and heating network on the basis of self-balancing capability. The multi-source complementarity is realized, and the “generation-grid-load-storage” coordination strategy is put forward. Considering the sizing cost and the typical scenario operation revenue, carbon emissions and primary energy consumption, and the feasibility and security constraints, multi-energy system optimal programming mathematical model is established. Analysis shows that the multi-energy system programming scheme which is considering the typical scenarios operation achieves the optimal effect of sizing cost and running comprehensive benefit.
