Under the condition of suitable formulation, the power system can be away from the voltage collapse point, through controlling the left eigenvector of voltage collapse point.

In recent years, more and more researchers have realized that voltage stability of power system is a dynamic phenomenon, and voltage collapse point can be predicted in advance.

近些年，越来越多的人认识到电力系统电压稳定问题是一个动态问题，而电压崩溃点是可以提前预知的。

In the meantime, it is also proven that the non transversal intersection mentioned above exactly corresponds to the static bifurcation point, i. e. the critical point of voltage collapse.

文中还证明了这一非横截交点恰好对应于静态分岔点即电压崩溃的临界点。文中结果对于防止电压崩溃、保证系统安全运行具有重要意义。

Now there is growing concern that a really big storm might collapse much of the global electric grid, particularly in places with long high-voltage transmission lines such as Australia, Canada, China and the United States.
