The increase in penetration level causes a decrease in the system inertia resulting in a reduced critical modes damping of the system [ 54 ]. In the studies of PV penetration regarding the frequency stability, Alquthami et al. [ 55] have assessed penetration levels of 5%, 10%, and 20% while keeping SGs in the system.
