Abstract: The frequency response characteristics of inverter-based resources (IBRs) and synchronous generators (SGs) vary significantly during system contingencies, often resulting in prolonged ...

A group of researchers in Australia has outlined a new methodology to determine the minimum power rating of energy storage systems (ESSs) used for emergency under-frequency response. The ESS size must ...

Large-scale photovoltaic (PV) integration into microgrids often leads to reduced inertia, diminished damping, and increased generation intermittency. To address these challenges, this paper proposes a ...

Abstract: The Virtual Synchronous Machine (VSM) is a promising control concept that enables converter-coupled resources to provide instantaneous reserve as an ancillary service to the system. As ...

As more renewable energy sources and battery storage units are specified and incorporated into power systems, consultant specifying engineers are faced with many challenges that could impact the ...

In simple terms, inertia refers to the energy stored in the rotating masses of synchronous generators, typically found in traditional thermal power plants. This stored kinetic energy acts as a cushion ...

As coal and gas plants are taken offline to be replaced by wind and solar, grid stability and system strength can become serious challenges. This is due to the inherent inertia provided by rotating ...
