This study proposes a novel approach for estimating the power system‐wide inertial frequency response (IFR) using strategically allocated phasor measurement units (PMUs). First, a method is presented to identify generator clusters that form aggregated sources of inertial response. Then, the collective dynamics of each cluster are synthesised using PMUs placed at key network buses. These buses are identified as the inertial centres which accurately represent the centre of inertia motion. The proposed synthesis process ultimately yields IFR estimates at zonal and global (system‐wide) scales. Simulation results demonstrate the proposed methodology's ability to accurately estimate IFR under several operating conditions, network topology changes, and disturbances.
