In this complicated study background, this thesis deal with problems associated with the dynamic response of power systems to severe disturbance for studying mid-term and long-term voltage stability problems using QSS method introduced in recent years.

• 在这众说纷纭的复杂研究背景下，针对近年来兴起的中长期电压稳定问题研究和QSS方法，分析讨论的是电力系统动态响应的结果。 本文利用P.
