A novel procedure for estimating the total inertia of the Great Britain (GB) power system is presented, following an instantaneous in-feed loss, regional variations in the estimate of inertia are obtained from measured frequency transients using installed synchronised phasor measurement units (PMUs).Abstract:
A novel procedure for estimating the total inertia of the Great Britain (GB) power system is presented Following an instantaneous in-feed loss, regional variations in the estimate of inertia are obtained from measured frequency transients using installed synchronised phasor measurement units (PMUs) A method is proposed to first detect a suitable event for analysis, and then filter the measured transients in order to obtain a reliable estimate of inertia for a given region of the GB network The total inertia for the whole system is then calculated as a summation, with an estimate also provided as to the contribution to inertia from residual sources, namely synchronously connected demand and embedded generation The approach is first demonstrated on the full dynamic model of the GB transmission system, before results are presented from analyzing the impact of a number of instantaneous transmission in-feed loss events using phase-angle data provided by PMUs from the GB transmission network and also devices installed at the domestic supply at 4 GB universitiesread more

On-line inertia estimation of Virtual Power Plants
TL;DR: In this paper , an on-line estimation method to track the equivalent, time-varying inertia provided by Virtual Power Plants (VPPs) is presented, which relies on the estimation of the rate of change of the active and reactive power at the point of connection of the VPP with the rest of the grid.
