Dynamic Stability is a way to describe how well an electrical power system can stay steady and recover after unexpected problems like equipment failures or sudden changes in power demand. Think of it like a car's ability to stay on the road and recover after hitting a bump. In power systems, this is crucial because electricity needs to flow smoothly to homes and businesses without interruption. Engineers who work with Dynamic Stability help prevent blackouts and ensure reliable power supply by analyzing and improving how power systems handle disruptions.
