| 摘要: |
| 综合能源系统(integrated energy system, IES)是解决能源损耗和环境污染问题的有效途径。为提高IES的经济性和环保性，提出了一种基于一致性的IES低碳经济调度策略。首先，在IES中引入阶梯式碳交易机制，在碳交易成本函数构造中，提出一种随着碳排区间而递增的成本系数，通过成本的非线性递增来限制碳排放量。其次，综合考虑能量传输过程中的损耗问题，构建一种结合用能需求和传输损耗的供需平衡约束条件。然后，将电、热、气供能单元的增量成本作为一致性变量，利用领导一致性算法对IES进行分布式调度，进而实现各单元的供能最优输出。最后，结合不同的实验案例验证了所提低碳经济调度策略的有效性。 |

| Abstract: |
| Integrated energy system (IES) are an effective way to solve energy loss and environmental pollution problems. A consensus-based distributed dispatching method is studied to realize economical operation and the environmental protection of IES. First, a stepped carbon trading mechanism is studied, where a non-linear cost coefficient that increases with the carbon emission interval is designed to construct the carbon trading cost function. In this way, the amount of carbon emission is limited. Second, the power loss problem in the energy transmission process is considered, and a supply-demand balance constraint that combines energy demand and transmission loss is constructed. Third, the incremental costs of electricity, heat, and gas supply units are considered as the consensus variables. Then, a leader-following consensus algorithm is designed to perform the distributed scheduling of the IES, thus realizing the optimal output of energy supply for each unit. Finally, the effectiveness of the proposed low-carbon economic dispatching strategy is verified with some numerical experimental cases. |
