Coordinated Optimization Scheduling for Power Transmission and Distribution Considering Wind Power Integration

The integration of large amounts of new energy sources has given the distribution network more proactive capabilities, but traditional centralized scheduling methods with fragmented transmission and distribution cannot fully utilize the flexibility resources of the distribution network. Additionally, these methods are not conducive to protecting the privacy of the participating entities. Therefore, a model for coordinated optimization of transmission and distribution economic dispatch is proposed, and the Alternating Direction Method of Multipliers (ADMM) is used for distributed solving to protect the privacy of each entity. Case studies show that the coordinated optimization economic dispatch model can fully utilize various resources of the transmission and distribution networks, promote renewable energy integration, and achieve optimal system economy.
