Island frequency management guide

Island Frequency Management Guide Cover

As utilities for islands and electrically islanded systems make strides toward their decarbonization goals by increasing the mix of solar PV and wind power, they can encounter new grid stability problems unlike those experienced by larger, connected grids. With a tendency to be isolated and vulnerable to highly variable weather events, islands face unique grid challenges characterized by systems with low inertia and spinning reserve.

This guide offers islands and islanded grids frequency management solutions as they journey toward a grid powered 100% by renewables. It delves into the frequency management challenges associated with low-inertia grids and offers solutions for stabilizing frequency while adding more intermittent renewable power generation resources.
