This article presents a new mixed-integer second-order cone programming model for solving the restoration problem in active distribution systems considering the optimal control of distributed generators (DGs), voltage regulators (VRs), on-load tap changers (OLTCs), and capacitor banks (CBs). In contrast to most of the works found in the literature, temporary loops may be formed in the network during the restorative operation state. This operating condition allows restoring the service to more loads. In this way, the objective function of the problem minimizes (i) the total load not supplied, (ii) the number of switching operations, (iii) the changes in the statuses of the voltage control devices and in the dispatch of the DGs, and (iv) the number of basic loops formed in the system. Several tests are carried out using a 53-node system for single-fault and multiple-fault scenarios. The results obtained with the proposed approach outperform the solutions achieved when only radial configurations are allowed in the problem. Moreover, it is also verified that the voltage control allows for more efficient restoration schemes.

具有电压控制和闭环运行的主动配电系统的优化恢复


本文提出了一种新的混合整数二阶锥规划模型，用于解决主动配电系统中的恢复问题，考虑了分布式发电机（DG）、电压调节器（VR）、有载分接开关（OLTC）和电容器组（CB）。与文献中的大多数工作相反，在恢复操作状态期间网络中可能会形成临时环路。这种操作条件允许恢复更多负载的服务。通过这种方式，问题的目标函数最小化（i）未供电的总负载，（ii）开关操作的数量，（iii）电压控制设备的状态变化和DG的调度， (iv) 系统中形成的基本环路的数量。使用 53 节点系统针对单故障和多故障场景进行了多项测试。使用所提出的方法获得的结果优于问题中仅允许径向配置时获得的解决方案。此外，还验证了电压控制可以实现更有效的恢复方案。
