软常开点（SNOP）是安装在配电网常开点的电力电子设备。这样的电力电子装置能够控制功率流以平衡馈电线之间的负载，减少网络损耗并调节电压。研究了SNOP在中压配电网馈线负荷平衡中的性能。稳态模型的两种不同类型的SNOP开发：背靠背电压源型变换器和统一潮流控制器。使用SNOP的好处进行了量化，通过求解组合非线性优化，使用鲍威尔的直接集方法。IEEE 33节点电力系统被用来证明SNOP的有效性。考虑了不同数量和类型的SNOP设备。通过与传统网络重构方法的比较，说明了SNOP方法的优越性。
Soft Normally-Open Points (SNOPs) are power electronic devices installed at normally-open points in a distribution network. Such power-electronic devices are able to control power flow to balance loads between feeders, reduce network losses and regulate voltage. The performance of SNOPs for feeder load balancing in a medium voltage distribution network was investigated. Steady state models of two different types of SNOP were developed: a back to back voltage-source converter and unified power flow controller. The benefits of using SNOPs were quantified by solving a combinational nonlinear optimization using Powell's direct set method. The IEEE 33-bus power system was used to demonstrate the effectiveness of SNOPs. Different numbers and types of SNOP devices were considered. The superiority of using SNOP was shown by comparing them with the conventional network reconfiguration.
