分布式电源的广泛应用显著增加了配电网的复杂性，配电网与微电网（群）之间的协同有助于促进分布式能源消纳，但传统优化方法难以应对大规模非凸最优潮流问题，难以有效处理大规模系统的计算复杂性。为此，提出了一种基于半正定规划的配电网-微电网群分层调度方法，通过减少半正定矩阵约束的计算量，显著提高了半正定规划松弛模型的求解效率。实验结果表明，该方法在处理大规模电力系统时具有明显的计算优势，有助于推动电力系统最优潮流问题的进一步研究。
Abstract：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.
