基于半正定规划松弛的配-微电网协同调度方法
A coordinated dispatch method for distribution and microgrid systems based on semidefinite programming relaxation
摘要
Abstract
The widespread adoption of distributed energy resources(DER)has significantly increased the complex-ity of distribution networks.Coordination between distribution networks and microgrid(s)can facilitate the integra-tion 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 program-ming(SDP)is proposed.By reducing the computational burden of semidefinite matrix constraints,the solving effi-ciency 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 fur-ther research on OPF problems in power systems.关键词
