Abstract

The topology of distribution network can be modified time to time using sectionalizing and tie-switches for enhancement of voltage stability index to minimize system losses. This will also improve the voltage profile of each node. This paper proposes a novel method for hourly switching action for 16-node and 33-node radial distribution network for a single day by feeder reconfiguration considering static load model. At each node different load is considered. The active and reactive power of these loads are dependent on voltage magnitudes. The result shows that minimum voltage stability index is found at node where it has low voltage profile and higher losses.
通过电网重构提高配电网电压稳定指标,包括静态负荷模型和日负荷曲线
配电网的拓扑结构可以通过分段和配线开关随时进行修改,以提高电压稳定指标,使系统损耗最小化。这也将改善每个节点的电压分布。本文提出了一种考虑静态负荷模型的馈线重构方法,对16节点和33节点的径向配电网进行单日小时切换。在每个节点上考虑不同的负载。这些负载的有功和无功功率取决于电压的大小。结果表明,电压分布低、损耗大的节点电压稳定指数最小。
