It involves a power system state where the grid exchanges considerable energy with a generator turbine set in one or some natural sub-synchronous torsional modes [25], [26]. This type of oscillation can have a poorly damped, growing damped, or undamped nature [25] .
v. t. e. An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers.
The grid needs conventional backup power and huge energy storage so as it can accommodate more renewable energy would need large quantities of conventional backup power and huge energy storage. This is necessary to accommodate the natural variations and intermittence of energy supply in terms of time of day, and season
