| 摘要: |
| 在“双碳”目标背景下，针对实现配电网低碳经济运行问题，提出了一种“源-网-荷-储”协调控制的配电网低碳经济优化方法。首先，以考虑弃风弃光成本、柔性负荷与储能装置调度成本、碳排放成本等的配电网综合成本最小为目标函数进行建模。其次，通过二阶锥松弛技术，将其转变为混合整数凸规划模型，进一步提高计算速率。然后通过修改的IEEE 33节点配电系统证明了该方法在降低配电网经济成本和碳排放方面的优越性。最后，对“源-网-荷-储”协调优化中不同降碳措施的效果进行了灵敏度分析，并以此为基础研究了协调低碳经济运行与传统经济运行之间矛盾与统一的博弈关系，得出了在不同环境条件下两种运行方式之间的相同点与差异点。 |

| Abstract: |
| Under the “dual-carbon” goal, a low-carbon economic optimization method for distribution networks based on “source-grid-load-storage” coordinated control is proposed. First, a model is developed with the objective of minimizing the comprehensive costs of the distribution network, considering factors such as wind and solar curtailment costs, flexible load and energy storage dispatch costs, and carbon emission costs. Second, second-order cone relaxation technology is employed to transform the problem into a mixed integer convex programming model for improving computational efficiency. Then, a modified IEEE 33-bus system is used to demonstrate the superiority of the proposed method in reducing both economic costs and carbon emissions. Finally, a sensitivity analysis is conducted on the different carbon reduction measures in the coordinated optimization of “source-grid-load-storage”. Based on this, the trade-off between coordinated low-carbon economic operation and traditional economic operation is explored, identifying similarities and differences between the two approaches under various environmental conditions. |
