Stability and Frequency Regulation of Inverters with Capacitive Inertia [PDF]
, 2017 In this paper, we address the problem of stability and frequency regulation of a recently proposed inverter. In this type of inverter, the DC-side capacitor emulates the inertia of a synchronous generator.

Protention and retention in biological systems [PDF]
, 2011 This paper proposes an abstract mathematical frame for describing some features of cognitive and biological time. We focus here on the so called "extended present" as a result of protentional and retentional activities (memory and anticipation).

Effect of DFIG control parameters on small signal stability in power systems
Scientific Reports, 2023 The doubly-fed induction generator (DFIG) with virtual inertia control and reactive damping control gives a renewable energy generation system inertia and damping characteristics similar to those of a thermal power plant, and the parameters of the ...

On the virtual inertia provision by BESS in low inertia power systems [PDF]
2018 IEEE International Energy Conference (ENERGYCON), 2018 This paper emphasizes the importance of battery energy storage systems (BESS) for frequency stability in low inertia power systems. A mixed input signal is considered for the BESS control, consisting of the frequency variation and the rate of change of frequency, as a solution to deploy the BESS for providing both inertia and primary frequency control.

Dynamic Frequency Support from a DFIG-Based Wind Turbine Generator via Virtual Inertia Control
Applied Sciences, 2020 As the penetrated level of wind in power grids increases, the online system inertia becomes weak. Doubly-fed induction generator (DFIG)-based wind turbine generators (WTGs) are required to provide virtual inertia response to support system frequency. The

Optimal Allocation of Virtual Inertia Devices for Enhancing Frequency Stability in Low-Inertia Power Systems [PDF]
2021 North American Power Symposium (NAPS), 2021 As renewable resources gradually replace conventional generation based synchronous machines, the dynamics of the modern grid changes significantly and the system synchronous inertia decreases substantially. This transformation poses severe challenges for power system stability; for instance, it may lead to larger initial rate of change of frequency and
