摘　　要：复杂网络理论中的网络结构抗毁性从自身连接性角度描述了网络抵御破坏的能力。文中将其引入配电网网架规划中,建立了以投资、维护、运行费用之和最小,以及网络抗毁度最大为目标的配电网网架多目标规划模型,并采用向量序优化方法优化该多目标模型。向量序优化理论包括排序比较和目标软化等核心思想,能确保以很高的概率求得足够好的解,计算量大大减少,可以满足配电网规划寻求最优或次优方案的工程需要。算例优化结果表明,采用向量序优化求解配电网网架规划可以找到较优的规划方案,且与现代启发式算法相比,计算时间更少,搜索效率更高。From the perspective of connectivity,network survivability in the complex network theory describes the networks ability to resist damage.The concept of network survivability is introduced into distribution network planning.A multi- objective distribution network planning model is developed with the cost of investment,maintenance and operation minimal and the networks invulnerability maximal as the objective.And the multi-objective model is optimized with vector ordinal optimization.The vector ordinal optimization theory including sorting comparison and target softening is capable of ensuring good enough solution with high probability,meeting engineering needs for optimal or suboptimal solution in distribution network planning.Numerical example has verified that good solutions can be found much more rapidly by vector ordinal optimization than by modern heuristic algorithms.
