Dynamic security enhancement strategies for power systems

我们没有意识到，但我们家的电源插座实际上是有史以来最大和最复杂的物体之一的门户！输电系统是20世纪世纪最伟大的工程成就之一。它是一个广泛的互联网络系统，其中高压电力线将电力从发电机输送到客户。我们的生活水平取决于可靠、低成本和高质量的能源供应。 然而，不可预见的事件发生，可能会干扰电能的可靠供应。还记得2003年8月的大停电吗！这给人民造成了极大的困难，给经济造成了巨大损失。一开始是一条高压输电线垂到树上。一条输电线路的断开导致其他线路携带更多的电力，这导致了“多米诺骨牌”效应，导致连锁停电和停电。 这种潜在的危险总是存在的，工程师们正在寻找使电网对这些可能的干扰更加“鲁棒”的方法。解决这个问题的方法通常被称为“安全增强”。

We don't realize it, but the electrical outlet at our homes is actually a gateway to one of the largest and most complex objects ever built ! The electricity transmission system is one of the greatest engineering achievements of the 20th century. It is an extensive system of interconnected networks in which high voltage power lines transport electricity from generators to customers. Our standard of living depends on reliable, low-cost and high-quality availability of energy. However, unforeseen events occur that can disturb the reliable supply of electrical energy. Remember the blackout of August 2003 ! This caused significant hardship to the people and a great loss to the economy. It started with a high voltage transmission line sagging on to a tree. Disconnection of one transmission line caused other lines to carry more power and this resulted in a 'domino' effect resulting in cascading outages and blackout. This potential danger is always present and Engineers are looking for ways to make the electrical grid more 'robust' to these possible disturbances. The approach to tackle this problem is referred to in general as 'Security Enhancement'.
