Keeps power grids stable with renewable energy.
The increasing penetration of renewable energy sources reduces rotating inertia and even frequency control capacity, affecting frequency stability. This challenge is significant in \gls{ips} that already suffer from low inertia and frequency control capacity. This paper presents a comparative study on different \gls{fcuc} formulations applied to \gls{ips}. Then, by considering under-frequency load shedding as a significant measure of frequency stability in \gls{ips}, two indices are presented to fully compare the formulations from system benefits and computational burden perspectives. Simulations conducted on a real Spanish island show that the data-driven corrective \gls{fcuc} formulation has the most advantages among other formulations.
