Low-Voltage Ride-Through Algorithm for Grid-Forming Converters
IEEE Transactions on Power ElectronicsIn recent years, the increasing integration of renewable energy sources into power systems has led to significant changes in grid operation. Power electronic converters are primarily used to connect these power plants to the electrical system and, as key components in modern power systems, grid-forming (GFM) converters have emerged to provide the ...

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Journal of the Association for Information Science and Technology, EarlyView.Abstract Online technologies are required for accessing essential services, such as healthcare, transportation, and education. Challenges to online technology access can prevent resource‐constrained communities from connecting to these services. Human intermediaries who act in the middle space between technology and the person using the technology may ...
