Understanding and quantifying the inertia of power systems with the integration of converter-
interfaced generation (CIG) plays an essential role in the safe transition to a future low …

Several studies show that grid-integrated renewable energy (RE) sources have the potential
to replace conventional synchronous generators in the network. This means the grid will …

This study presents a method of estimating the effective inertia of a power system from
ambient frequency and active power signals measured by phasor measurement units. Most …

The worldwide motivation to use renewable energy sources and power electronics
interfaced electric drive loads has not only reduced the power system inertia constant but …

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 …

This paper proposes an on-line estimation method able to track the inertia of synchronous
machines as well as the equivalent, possibly time-varying inertia from the converter …

In order to maintain operational security of the power system its frequency must lie within a
predefined range, and not deviate too far from the frequency for which the system was …

Accurate inertia estimates and forecasts are crucial to support the system operation in future
low-inertia power systems. A large literature on inertia estimation methods is available. This …

This paper presents an improved method to estimate the available inertia in an islanded AC
microgrid. Inertia estimation is carried out based on measured frequency response for any …

Offnominal power system frequency regimes play a key role in the propagation of disturbed
system conditions and blackouts. The evolution of power systems will make the availability …
