Placing Monitoring Devices in Electric Power Networks Modeled by Block Graphs.
<p>The problem of monitoring an electric power system by placing as few measurement devices in the system as possible is closely related to the well known vertex covering and dominating set problems in graph theory. A set <em>S</em> of vertices is defined to be a power dominating set of a graphs if …

The effect of weather and climate change on the operation of meshed power networks
Weather outages affect power systems all over the world. In January 1998 Canada experienced the 'Great Ice Strom' which hit an area spanning from Eastern Ontario to Southern Quebec. 15 years later, it experienced another ice storm which left 600,000 people without power at the peak. Wind storms can …
