The system inertia is the inherent ability of the online synchronous machines to oppose sudden changes in generation or load. With increasing share of non-synchronous generation technologies (e.g., wind and solar generation) system inertia could decrease. One of the options to address system inertia decline is to increase frequency response reserves to achieve a satisfactory frequency control. This letter discusses a new prototype tool developed in Electric Reliability Council to forecast system inertia and to evaluate adequacy of frequency response reserves. The performance of this prototype tool is also evaluated.
