Abstract

In this paper the problem of network congestion due to high penetration of Distribution Generation (DG) in Distribution Networks (DNs) via network reconfiguration is examined. The problem in DNs is differentiated from the respective one in Transmission Networks (TNs), since the former is examined through a technical perspective while the latter through an economical orientated aspect. In this work, DN congestion is established as the problem of increased loading of the DN branches due to bi-directional power flow. The latter is expected to occur when the load demand of the DN is low and the power production of DG is high. Therefore, a Congestion Indicator Factor (CIF) is introduced in order to describe the tendency of DN towards congestion. Based on the CIF values, network reconfiguration is proposed as a real time solution regarding the online management of the DN in order to mitigate congestions. Results indicate that local reconfigurations could yield both congestion reduction and voltage profile improvement.

通过网络重构减少高DG渗透率配电网的网络拥塞

本文研究了通过网络重构引起的配电电源在配电网中的高渗透率所导致的网络拥塞问题。DNs中的问题与传输网络中的问题是有区别的，因为前者是从技术角度来研究的，而后者是从经济角度来研究的。本文将DN拥塞定义为双向潮流导致DN支路负载增加的问题。后者预计会在DN的负载需求较低而DG的发电量较高时发生。因此，为了描述DN的拥塞趋势，引入了拥塞指标因子(CIF)。基于CIF值，提出了网络重构作为在线管理DN的实时解决方案，以缓解拥塞。结果表明，局部重构既可以减少拥塞，又可以改善电压分布。
