Grid-forming and Grid-Following Dual-Mode Switching Strategy Based on APS-IPSO for Grid-Forming Energy Storage [PDF]
Dianli jianshe[Objective] Addressing the challenge that grid-forming energy storage converters，operating in a single mode，struggle to adapt to variations in grid short-circuit ratio and complex fault disturbances，this paper proposes a dual-mode switching strategy ...

Grid-forming frequency shaping control
CoRR, 2020 As power systems transit to a state of high renewable penetration, little or no presence of synchronous generators makes the prerequisite of well-regulated frequency for grid-following inverters unrealistic. Thus, there is a trend to resort to grid-forming inverters which set frequency directly. We propose a novel grid-forming frequency shaping control

Dynamic Effect of Input-Voltage Feedforward in Three-Phase Grid-Forming Inverters
Energies, 2020 Grid-connected and grid-forming inverters play essential roles in the utilization of renewable energy. One problem of such a converter system is the voltage deviations in the DC-link between the source and the inverter that can disrupt the inverter ...

Fault ride‐through control based on voltage prioritization for grid‐forming converters
IET Renewable Power Generation, 2023 This paper discusses that the existing grid codes on the fault ride‐through (FRT) operation have certain complications to be implemented in the grid‐forming (GFM) converters.
