摘要: 根据含分布式电源(distributed generation, DG)的配电网运行特点,提出一种综合考虑网络重构与孤岛划分的故障恢复运行策略。首先,通过对传统重构问题中相关约束的修改,使其允许切负荷操作与产生孤岛,并且使孤岛运行与重构操作相配合进行;然后,采用约束中0-1状态变量简化网络模型,提高运算效率;最后,采用二阶锥松弛技术将原始非凸非线性问题优化松弛为标准混合整数二阶锥规划(mixed integer second-order cone programming, MISOCP)问题,使其得以求解。算例结果证实了该策略的有效性,与其他算法的对比证实了该算法的优越性与准确性。

Abstract: According to the operating characteristics of active distribution network, a fault recovery strategy, which can rationally coordinate the distribution network reconfiguration with isolated island partitioning, is presented. Firstly, load cutting and island partitioning are permitted by changing the constraints of traditional network reconfiguration model. Then, 0-1 state variables in constraints are used to simplify the primary model and improve calculating efficiency. Finally, the second-order cone relaxation technique is adopted to convert the original nonconvex nonlinear problem into a mixed integer second-order cone programming (MISOCP) problem, which can be solved easily. Simulation results on modified IEEE 33-bus system show the effectiveness of the strategy. Comparisons with other algorithms demonstrate the superiority and accuracy of algorithm in this paper.

Key words: fault recovery, network reconfiguration, island partitioning, mixed integer second-order cone programming (MISOCP), distributed generation(DG)
