Enhanced Virtual Inertia Controller for Microgrid Applications
Energies, 2023 Unlike Synchronous Generators (SGs), Virtual Synchronous Generators (VSGs) inertia is not fixed once it is manufactured and only has an upper limit defined by its energy storage components. In this paper, a novel Enhanced Virtual Inertia Controller (EVIC) is proposed.

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

Virtual Synchronous Generator Using an Intelligent Controller for Virtual Inertia Estimation [PDF]
Electronics, 2021 Virtual synchronous generators (VSGs) with inertia characteristics are generally adopted for the control of distributed generators (DGs) in order to mimic a synchronous generator. However, since the amount of virtual inertia in VSG control is usually constant and given by trial and error, the real power and frequency oscillations of a battery energy ...

Dynamic Virtual Inertia and Damping Control for Zero-Inertia Grids
CoRRIn this paper virtual synchronous generation (VSG) approach is investigated in application to low- and zero-inertia grids operated by grid-forming (GFM) inverters. The key idea here is to introduce dynamic inertia and damping constants in order to keep power gird stable during different types of faults, islanding or large power balance oscillations. In
