Grid-Forming Inverters: A Critical Asset for the Power Grid
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 Increasing inverter-based sources reduces the system’s inertia resulting in possible frequency stability issues. Understanding low-inertia systems and their stability properties is of crucial importance.

Current Limiting Control With Enhanced Dynamics of Grid-Forming Converters During Fault Conditions
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 With an increasing capacity in the converter-based generation to the modern power system, a growing demand for such systems to be more grid-friendly has emerged. Consequently, grid-forming converters have been proposed as a promising solution as they are

Virtual Tryout: Case Study on Simulation-Based Design and Die Spotting of Forming Tools
Engineering Proceedings, 2022 The iterative development process of forming tools is cost- and labor-intensive. The main reason for this is the high complexity of interaction between forming machine, tool structure, and process, which is currently only partially taken into account in ...

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,
