摘　　要：分布式电源的迅速发展,给配电网重构带来诸多影响。本文构造了含分布式电源的配电网重构模型,将分布式电源的类型考虑在内,提高了重构后运行的可靠性。另外,模型把辐射状约束建立于解析型表达之上,引入非线性互补约束,提出相应的非线性互补算法,解决了求解离散量存在的时间与精度之间的矛盾。本文所提出的重构模型和算法能够保证配电网时刻处于最佳的运行状态。经105节点等系统的计算结果表明,该方法具有收敛性好、计算速度快的特点。The rapidly developing distributed generation（DG）has influenced the distribution network from many aspects.In this paper,a reconfiguration model of distribution network with DG is proposed. By taking into account different types of DG,the reliability after reconfiguration is improved. The proposed model adds the radial constraints to the analytical expression,which is further solved by nonlinear complementary algorithm with the introduction of complementary constraints. In this way,the contradiction between time and precision is overcome effectively.The proposed model can ensure that the distribution network works optimally. The result of a 105-node test system shows that,the proposed model has good convergence and fast computation speed .
