摘要/Abstract

摘要：

随着智能电网技术的不断发展,对高可靠性的智能电网的精确评估提出了更高的要求。智能电网中重要节点的故障将会导致大规模停电,因此对智能电网中重要节点的评估是评估智能电网可靠性程度的重要体现。文中针对节点所处的局部环境、全局属性、网络拓扑结构以及节点所承载负荷等级等多个不同的动静态综合指标进行研究,以这些综合指标模型来评估节点在智能电网中的重要度,最后使用TOPSIS方法将动静态指标糅合,共同对智能电网节点重要度进行评估,并对IEEE-30节点进行了仿真验证。结果显示节点6的重要度较高,应对其重点保护。

Abstract:

With the continuous development of smart grid technology, the scientific and accurate evaluation of smart grid with high reliability is required. The failure of important nodes in the smart grid will lead to large-scale power outages, so the evaluation of the important nodes in the smart grid is an important manifestation of evaluating the reliability of the smart grid.In this study, different dynamic and static comprehensive indicators such as local environment, global attribute, network topology and load level of nodes are studied. These comprehensive indicator models are used to evaluate the importance of nodes in smart grid. Finally, the TOPSIS method is adopted to combine dynamic and static indicators to evaluate the importance of smart grid nodes, and the IEEE-30 nodes are simulated and verified. The results show that the importance of node 6 is relatively high, which should be protected.

Key words: smart grid, dynamic and static indicators, node importance degree, betweenness, network efficiency, load grade, node deletion, TOPSIS
