Grid-Forming Services From Hydrogen Electrolyzers

IEEE Transactions on Sustainable Energy, 2023
Hydrogen electrloyzers are power-to-gas storage devices that can facilitate large-scale integration of intermittent renewable sources into the future power systems. Due to their fast response and capability to operate in different loading conditions, they can be used as responsive loads providing support to AC grid during transients.

Overview on Grid-Forming Inverter Control Methods

Energies, 2020
In this paper, different control approaches for grid-forming inverters are discussed and compared with the grid-forming properties of synchronous machines. Grid-forming inverters are able to operate AC grids with or without rotating machines. In the past,

Generic PLL-Based Grid-Forming Control [PDF]

IEEE Transactions on Power Electronics, 2021
In grid-forming control, the swing equation of a synchronous machine is emulated by a power controller. Thereby, frequency droop, power-oscillation damping, and/or virtual inertia can be obtained. In this letter, it is shown that a phase-locked loop - which is normally grid following - can be designed so as to, in turn, emulate a generic power ...
