Frequency Shaping Control for Weakly-Coupled Grid-Forming IBRs
IEEE Control Systems Letters, 2023 We consider the problem of controlling the frequency of low-inertia power systems via inverter-based resources (IBRs) that are weakly connected to the grid. We propose a novel grid-forming control strategy, the so-called frequency shaping control, that aims to shape the frequency response of synchronous generators (SGs) to load perturbations so as to ...

Direct AC voltage control for grid-forming inverters [PDF]
Journal of Power Electronics, 2019 Grid-forming inverters usually use inner cascaded controllers to regulate output AC voltage and converter output current. However, at the power transmission system level where the power inverter bandwidth is limited, i.e., low switching frequency, it is difficult to tune controller parameters to achieve the desired performances because of control loop ...

Grid-forming control methods for weakly connected offshore WPPs
IET Conference Proceedings, 2023 Grid-forming control (GFC) has seen numerous technological advances in their control types, applications, and the multitude of services they provide. Some examples of the services they provide include black start, inertial frequency response, and islanded operation capabilities with the possibility of re-synchronization without the need of additional ...
