摘要/Abstract

摘要： 现代配电网呈网状建设、辐射状运行，以提升故障情况下的转供能力。传统配电网规划方法一般采用规划设计-可靠性评估两阶段迭代计算方式，只能得到粗放规划方案。为此，提出了考虑可靠性约束的配电网多阶段扩展规划方法。通过将可靠性指标计算过程解析化，并嵌入规划模型中，可以精确考虑故障隔离、负荷转供和恢复策略。基于线性化潮流，该规划模型是一个典型的混合整数线性优化问题，可以有效求解。在54节点系统来验证所提方法的性能。仿真结果表明了该方法的有效性和灵活性。

关键词: 配电网, 多阶段扩展规划, 显式可靠性, 网络重构, 混合整数线性规划

Abstract: Modern distribution networks are often constructed in grid and operated in a radial manner to improve the transfer capacity under fault conditions. The traditional distribution network planning method generally adopts the two-stage iterative calculation method of planning design and reliability evaluation, which can only obtain an extensive planning scheme; the resulting planning scheme is either over invested or unable to meet specific reliability requirements. Therefore, a multi-stage distribution network expansion planning method considering reliability constraints is proposed. The reliability index calculation process is analyzed and embedded into the planning model, which can accurately consider the fault isolation, load transfer and recovery strategies. Based on the linearized power flow, the planning model is a typical mixed integer linear optimization problem, which can be effectively solved. The performance of the proposed method is verified in the Portugal 54-node system. The simulation result proves the effectiveness and flexibility of this method.

Key words: distribution network, multi-stage expansion planning, explicit reliability, network reconfiguration, mixed integer linear programming
