| 摘 要： | 自组织临界理论和熵概念在电力系统连锁性故障及复杂性分析方面已取得重要应用。结合相关研究成果,提出了基于N-1安全校核的支路开断风险熵指标,并将其应用于基于PSASP/UPI程序的多运行状态断面混合仿真平台,实现了对电力系统的静态安全风险评估及慢动态演化趋势研究。7机10节点系统的算例仿真结果表明,与传统的潮流熵指标相比,文中提出的指标在反映各支路静态安全宏观风险大小和微观异构性方面更具优势,有助于定量评估电网安全风险点和薄弱环节。

| Abstract: | The theory of self-organized criticality and entropy has been widely applied to complexity analysis of cascading failure in grids. By referring to relevant research achievements, an entropy evaluation index of branch circuit outage is proposed, and a new hybrid simulation platform of multi-time scale based on PSASP/UPI is developed to achieve a macro assessment of static security risk and its evolution trend. In the end, a simulation analysis of 7-machine 10-bus system verifies that the proposed indicators have greater advantage in reflecting fault behavior and micro heterogeneity as well as contributing to risk identification and vulnerability searching in power systems compared with the traditional power flow entropy index.
