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 car-bon 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 net-work is used as an example to conduct various analyses of the scheduling results,verifying the effective-ness of the proposed model.
