Unified Grid-Forming/Following Inverter Control
IEEE Open Access Journal of Power and Energy, 2022 The paper describes an inverter control scheme which incorporates both a phase-locked loop (PLL) for voltage synchronization and power-frequency droop for load sharing.

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.

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 ...

Voltage Sensorless Grid-Forming Power Converters
2020 IEEE 21st Workshop on Control and Modeling for Power Electronics (COMPEL), 2020 During the years, synchronization systems in power converter control has been mainly used for estimating the phase angle and the magnitude of the grid voltage, this estimated information is usually used for droop control strategies to ensure power sharing among power converters.

IET Generation, Transmission & Distribution, 2023 One of the main capabilities of grid‐forming converters is the ability to operate in both islanded and grid‐connected modes. The grid‐forming converters work autonomously and behave as an AC voltage source when they are isolated from the bulk power ...
