| 摘要: |
| 针对综合能源系统(integrated energy system, IES)中热储元件碳排放流刻画不精确以及多园区供需双侧的灵活性提升问题，提出了一种考虑热储扩展碳排放流的多园区综合能源系统低碳经济调度方法。首先，基于热储元件热耗散效应建立了热储扩展碳排放流模型。其次，构建了多园区综合能源系统供需双响应低碳模型，在园区供应侧考虑有机朗肯循环(organic Rankine cycle, ORC)实现热电联产(combined heat and power, CHP)机组热、电灵活输出响应，需求侧考虑电、热、气负荷的可转移性与可替代性。最后，形成了以上层电-气网络调度成本最低，下层能量枢纽(energy hub, EH)的购能、碳交易、需求侧响应综合成本最小为目标的双层低碳经济调度策略。通过设置多个场景进行仿真分析，结果显示该低碳经济调度策略使多园区综合能源系统的总运行成本降低了3.51%，碳排放量减少了8.72%。 |

| Abstract: |
| To address the inaccurate characterization of thermal storage carbon emission flow in integrated energy systems (IES) and to enhance the flexibility of both supply and demand sides across multiple energy parks, this paper proposes a low-carbon economic dispatch method for multi-park IES, which considers the augmented carbon emission flow of thermal storage. First, based on the heat dissipation effect of thermal storage, an augmented carbon emission flow of thermal storage is established. Second, on the supply side, the organic Rankine cycle (ORC) is used to achieve flexible thermal and electrical output from combined heat and power (CHP) units, while on the demand side, the transferability and substitutability of electricity, heat, and gas loads are considered, to construct a dual-response low-carbon model of multi-park IES. Finally, a bi-level low-carbon economic dispatch strategy is formulated, aiming to minimize the upper-level electricity-gas network scheduling cost and the lower-level energy hub cost, which includes energy procurement, carbon trading, and demand-side response. Through scenario-based simulation analysis, the results demonstrate that the low-carbon economic dispatch strategy reduces the total operational cost of the multi-park IES by 3.51% and carbon emissions by 8.72%. |
