On the 28 September 2003, a blackout affected more than 56 million people across Italy and areas of Switzerland. Estimates vary for the number of fatalities that were directly related to the loss of power. 30,000 people were trapped on trains. Several hundred passengers were stranded on underground transit systems. There were significant knock-on effects across other critical infrastructures. M...

Many blackouts occur with time scales that would permit emergency control by the operators. However, in order to perform this control the operators need to quickly know the state of system and implement timely, corrective control actions. This paper describes several visualization techniques that can be used to provide this information. Techniques discussed include the use of dynamically sized ...

Mid-span compression joints in overhead transmission line conductors need to give not only reliability, but also electrical and mechanical properties equivalent the original conductor. The use of an inappropriate joint can lead disastrous consequences. An example this is complete blackout Sri Lankan power system October 2009 through inadequate size joint. This paper based on investigations whic...

The power grid defines one of the most important technological networks of our times and sustains our complex society. It has evolved for more than a century into an extremely huge and seemingly robust and well understood system. But it becomes extremely fragile as well, when unexpected, usually minimal, failures turn into unknown dynamical behaviours leading, for example, to sudden and massive...
