Electronics Nuclear engineering The increasing share of renewable generation integrated in the traditional power systems network has brought new challenges to the utility.

The lack of inertia in the power system will increase the rate of change of frequency (ROCOF).

Furthermore, the results suggest that the increasing share of solar generation in the generation mix will result in the reduction of total system inertia.
