摘要

本文提出了一个三步分析方法来识别电压稳定问题使用现代网络分析工具。分析方法的第一步是建立一个用于偶然性分析的潮流模型。这允许识别系统稳态低电压或突发事件后的电压崩溃。第二步是应用优化算法/模型来确定无功裕度，或者确定消除低电压或电压崩溃所需的无功补偿的数量和位置。这一步生成P-V或Q-V曲线进行比较。最后一步是通过时域仿真验证电压稳定性对突发事件的响应，包括不同负载模型的影响。

Voltage stability assessment of the National Grid system using modern analytical tools

The paper presents a three-step analytical approach to identifying voltage stability concerns using modern network analysis tools. The first step in the analytical approach is to develop a load flow model for contingency analysis. This allows the identification of system steady-state low voltages or voltage collapses following contingencies. The second step is to apply an optimization algorithm/model to determine the reactive margin, or the amount and location of reactive compensation required to eliminate the low voltages or voltage collapses. P-V or Q-V curves are generated for comparison in this step. The final step is to verify the voltage stability response to the contingencies via time-domain simulation, including the impact of different load models.
