摘　　要：在配电网源端与荷端的不确定性变量增多、主动性增强的背景下,进行适应发展需要的网架规划具有重要的研究意义。对系统中的不确定变量和主动控制变量分类建模,对经济性、可靠性和安全性技术目标做柔性处理,提出计及源荷不确定性的主动配电网网架扩展柔性规划模型;提出包含问题解耦、简化潮流和逆向搜索3个步骤的求解流程;结合19节点算例系统进行验证,算例结果表明采用提出的柔性规划模型和方法求解网架扩展规划问题具有有效性和可行性。In the background of uncertain variables and initiative at source and load ends increasing in distribution network,thus the research of grid planning adapted to the development is of great significance. The uncertain variables and active control variables in the system are modeled respectively,the flexible methods dealing with the technical goals of economy,reliability and security are applied,and the flexible planning model of active distribution network expansion taking the source and load uncertainty into account is proposed. The solution flowchart that contains problem decoupling,simplifying flow and reverse searching is proposed. Taking the 19-bus system as an example,the results demonstrate the proposed flexible planning model and method are effective and feasible to solve the network expansion planning problem.
