“How can we measure how resilient the grid is?”
Grid reliability is a great way to measure the stability of the grid. But unfortunately, it does not give us the complete picture. When a grid systems experience are taken down, they need time to recover. The less time it takes, then the more resilient a grid will be. Taken the two systems in the picture for example. When the bottom one experiences a disruption, not only will it need a long time to recover but it does not reach close to its full potential again. In contrast, the top one only experiences a brief hiccup and quickly flows back to normal. This measure is called Grid Resilience and is an important part of the analysis of electrical systems.
