A group of researchers in Australia has outlined a new methodology to determine the minimum power rating of energy storage systems (ESSs) used for emergency under-frequency response. The ESS size must ...

As coal and gas plants are taken offline to be replaced by wind and solar, grid stability and system strength can become serious challenges. This is due to the inherent inertia provided by rotating ...

In simple terms, inertia refers to the energy stored in the rotating masses of synchronous generators, typically found in traditional thermal power plants. This stored kinetic energy acts as a cushion ...

People in the power industry understand inertia and its importance to grid stability. As large thermal power plants and other inertia-providing units are replaced with renewable resources that provide ...
