| description | The widespread adoption of distributed energy resources （DER） has significantly increased the complexity of distribution networks. Coordination between distribution networks and microgrid（s） can facilitate the integration of distributed energy， but traditional optimization methods struggle to address large-scale non-convex optimal power flow （OPF） problems and effectively handle the computational complexity of large-scale systems. To address this， a hierarchical dispatch method for distribution networks and microgrid clusters based on semidefinite programming （SDP） is proposed. By reducing the computational burden of semidefinite matrix constraints， the solving efficiency of the SDP relaxation model is significantly improved. Experimental results demonstrate that the proposed method exhibits notable computational advantages when applied to large-scale power systems， contributing to further research on OPF problems in power systems. |
