    摘 要:配電網是以閉環(huán)設計開環(huán)運行,在重構時需要建立相應的結構約束,來保證配電網結構的完整性。利用改進環(huán)網編碼策略對形成的孤島劃分,采用打捆 (設置禁忌支路組解集) 的方式避免不可行解的生成。以網損最小為目標函數(shù),建立相關潮流約束,通過二階錐規(guī)劃和 M 松弛將模型轉換為混合整數(shù)二階錐規(guī)劃模型。通過商業(yè)求解器 YALMIP 中的 CPLEX 建模工具對模型求解,并以 IEEE 33 節(jié)點為算例,驗證了提出的重構方法的有效性和可行性。

    Abstract: The distribution network is operated in open loop and designed in closed loop, so the corresponding structural constraint has to be established to ensure the integrity of the distribution network structure. The improved ring network coding strategy is adopted to divide the formed islands which are bundled (set up taboo branch group solution set) to avoid the generation of infeasible solutions. Then, the relevant power flow constraints are established to achieve the objective function of minimal network losses, and the second-order cone programming and M-relaxation are used to convert the model into a mixed integer second-order cone programming model. Finally, the model is solved by CPLEX modeling tool from a commercial solver YALMIP. The effectiveness and feasibility of the proposed reconfiguration method is verified by taking IEEE 33 nodes as an example.
    Key words: distribution network reconfiguration; active management element; second-order cone programming; M-relaxation
