The world is increasingly beset by severe weather events: heat waves, hurricanes, wildfires. Overall extreme events are impacting on power supply and distribution networks. Utilities are having to plan extensively about how to maintain electricity during emergencies.
One important aspect of this is ensuring that the utility can install a flexible demand response system ahead of any crisis, which can ensure a rapid load-management intervention. This can free up valuable resources for utilities, allowing them to shift those resources to other areas during large scale disasters. This article looks at three challenges in these circumstances and how to mitigate any disruption.
Severe weather usually harms the most vulnerable components of the grid: poles, lines and transformers. Customer loads need to be modulated to match reduced grid capacity until power can be rerouted or distribution assets can be repaired or replaced. This requires information about the entire grid and input from sensors located throughout.
Geographic grouping of demand response resources (at the substation level or other grid sections) can enable faster dispatch of these resources when grid assets are damaged.…
