摘要

基于复杂网络理论研究含分布式发电(DG, Distributed Generation)的电力网络脆弱度评估问题,
有针对性地提出三类脆弱度评估指标,其中基于结构的脆弱度指标能够体现网络拓扑和节点功率对系统供电效率的影响；攻击脆弱度指标可用于评估系统抵御节点和线路移除的能力；基于运行方式的脆弱度指标能够反映整个电网有功功率在传输距离上的均衡度.仿真算例验证了所提指标的有效性和DG对于改善系统功率传输性能与提高抗干扰能力方面的作用.

Abstract

Based on the complex network theory, three kinds of vulnerability indices are proposed to assess the vulnerability of the power grid with distributed generation(DG). The structure based index can consider the influence of network topology and node power on the supply efficiency. And the attack vulnerability index can assess the ability of the system to withstand node or line removal. Further, the index based on operational condition can reflect the power balance level of the whole power grid. At last, simulation results verify the validity of the proposed indices and the role of DG in improving transmission property and anti-disturbance ability of the power network.
