摘要

智能配电网的发展逐渐推动着配电网供电模式的改革，SNOP（soft normally open point）是代替联络开关的一种电力电子装置，它的引入彻底改变了配电网供电方式，给配电网的运行带来了诸多益处。首先，对SNOP的功能和原理进行详细介绍；然后，描述了SNOP的运行边界，提出含SNOP的配电网运行优化模型；最后，将SNOP优化效果和网络重构进行详细对比分析，从静态潮流优化、动态潮流优化、实时调整3个方面验证了SNOP的优势和潜在效益。

Abstract

The power supply mode of distribution network is being reformed cumulatively with the development of smart distribution grid. Soft normally open point (SNOP) refers to power electronic devices installed in place of a normally-open point

also called tie switch. In a medium-voltage distribution network

SNOP provides an alternative power supply mode and brings numerous benefits to the distribution network. Firstly

the benefits and theory of SNOP are presented. Secondly

the operation boundary and optimization model of distribution network with SNOP are proposed. Finally

the potential advantages of SNOP are verified by comparing with network reconfiguration from static and dynamic power flow optimization

as well as real-time adjustment. This work is supported by National Key Technologies R&D Program (No. 2013BAA01B03).
