| 摘要: |
| 为使虚拟电厂更好地适应多种低碳能源并存的碳市场，建立了一种基于对等架构的虚拟电厂-配电网协同调度双层模型。引入碳排放流理论，结合电网潮流确定节点碳排放责任。建立双层模型，上层为配电网最优潮流模型，下层为虚拟电厂点对点交易模型。上、下层模型间使用目标级联分析法构建对等架构，并通过共识变量实现协同调度。下层模型使用基于共识的自适应步长交替方向乘子法处理虚拟电厂间点对点交易问题，促进资源消纳的同时实现了隐私保护。以IEEE 33节点配电网为例，对调度结果进行多种分析，验证了所提模型的有效性。 |

| Abstract: |
| To better adapt virtual power plants to carbon market with multiple coexisting low-carbon energy sources, a dual-layer coordinated scheduling model for virtual power plants and distribution networks based on an equality architecture is established. The carbon emission flow theory is introduced, and the node carbon emission responsibility is determined by combining the power flow of the grid. A dual-layer model is established: the upper layer is the optimal power flow model of the distribution networks, and the lower layer is the peer-to-peer transaction model of the virtual power plants. An equality architecture is constructed between the upper and lower layers using the analytical target cascading method, and coordinated schedu-ling is achieved through consensus variables. The lower-layer model uses a consensus-based adaptive step-size alternating direction method of multipliers to handle peer-to-peer transactions between virtual power plants, promoting resource utilization while ensuring privacy protection. The IEEE 33-bus distribution network is used as an example to conduct various analyses of the scheduling results, verifying the effectiveness of the proposed model. |
