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 …

The increasing amount of solar photovoltaic (PV) penetration substitutes a large portion of
conventional synchronous power plants. During the peak power production period, it may …

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 …

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 …

The increasing penetration of power-electronic-interfaced devices is expected to have a
significant effect on the overall system inertia and a crucial impact on the system dynamics …

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 …

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 …

Originally, ancillary services (ASs) were provided by large-scale power plants to ensure the
secure and reliable operation of power systems. However, with the advent of renewable …

As the penetration of intermittent, low carbon generation increases, system inertia will
decrease dramatically and pose a major threat to system stability. The majority of research in …
