本文考虑了各种电压控制解决方案的影响，以促进分布式发电装置的电压违规发生之前，允许的水平增加。特别地，所关注的电压控制解决方案是“软”常开点（SNOP）的实现，“软”常开点是指安装在中压配电网中常开点的位置的电力电子设备，其允许控制其安装地点的每个端点之间的真实的和无功功率流。虽然SNOP安装的其他好处进行了讨论，本文的目的是确定是否SNOP是一个可行的替代其他电压控制策略，为这个特定的应用。因此，SNOP影响配电系统内沿着馈线的电压分布的能力与用于比较目的的其他电压控制选项集中在一起。不同拓扑结构的多个网络模型的研究结果，并考虑增加可行的DG渗透的经济效益的案例研究。
This paper considers the effects of various voltage control solutions on facilitating an increase in allowable levels of distributed generation installation before voltage violations occur. In particular, the voltage control solution that is focused on is the implementation of ‘soft’ normally-open points (SNOPs), a term which refers to power electronic devices installed in place of a normally-open point in a medium-voltage distribution network which allows for control of real and reactive power flows between each end point of its installation sites. While other benefits of SNOP installation are discussed, the intent of this paper is to determine whether SNOPs are a viable alternative to other voltage control strategies for this particular application. As such, the SNOPs ability to affect the voltage profile along feeders within a distribution system is focused on with other voltage control options used for comparative purposes. Results from studies on multiple network models with varying topologies are presented and a case study which considers economic benefits of increasing feasible DG penetration is also given.
