Balancing Cellular Autarky and System Frequency: An Inertia-Conscious Dispatch Concept

This paper proposes an operational framework to ensure short-term frequency security in inverter-dominated power systems with low and time-varying inertia. The core idea is to schedule frequency-effective upward reserve (dispatchable headroom) in advance so that sufficient fast active-power support is available immediately after credible contingencies, thereby limiting rate of change of frequency (RoCoF) and improving the frequency nadir.
