    摘 要:配电网是以闭环设计开环运行,在重构时需要建立相应的结构约束,来保证配电网结构的完整性。利用改进环网编码策略对形成的孤岛划分,采用打捆 (设置禁忌支路组解集) 的方式避免不可行解的生成。以网损最小为目标函数,建立相关潮流约束,通过二阶锥规划和 M 松弛将模型转换为混合整数二阶锥规划模型。通过商业求解器 YALMIP 中的 CPLEX 建模工具对模型求解,并以 IEEE 33 节点为算例,验证了提出的重构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
