Cyclonic resilience method developed off Texas power system

Smart Energy International

Based on a model of the Texas power system, scientists from the Potsdam Institute for Climate Impact Research PIK have developed a new method to identify and harden critical lines against tropical cyclones and increase power system resilience. Regions or cities fail in one major cascade, rather than gradually.

Exploring the resilience of the Texas power grid against extreme weather conditions

TechXplore

Climate change and global warming are expected to increase the risk of these events occurring, which could significantly disrupt activities in the area. The Gulf Coast of the United States is often hit by tropical cyclones (TCs), hurricanes and other extreme weather phenomena, which can cause widespread electricity outages.

As surging threats teeter electrical power grids, scientists offer insights to make them more resilient

Science Daily: Renewable Energy

Power grids -- the web of electrical networks that sprawl across countries and continents -- are under stress. Extreme weather events and volatile energy demands often push the system to the brink. The findings showed that recovering power within 13 hours can reduce up to 52% of the power loss stemming from cascading events.

Strengthening Puerto Rico’s power grid

Smart Energy International

As hurricanes threaten, Puerto Rico utilities are shoring up their defences using a PNNL-devised planning tool called the Electrical Grid Resilience and Assessment System (EGRASS), writes Nick Hennen from Pacific Northwest National Laboratory. Maria left many residents without power for nearly a year. million customers.

SDG&E unveils innovative microgrids in grid resilience bid

Smart Energy International

The four microgrid and energy storage sites will help address surging energy demands in the San Diego region, especially during hot summer days and the peak evening hours when solar power generation typically diminishes and there is a significant strain on the grid.
