title = "Enhancing Stability of dVOC Controlled Grid-Forming Inverters Under Large Grid Transients-A Power Angle Based Approach",
abstract = "The Grid-forming (GFM) inverter-based resources are increasingly gaining popularity which also invites the associated challenges especially when subjected to adverse grid conditions. The dispatchable virtual oscillator (dVOC) has shown promising potential to be suitable for GFM inverter control but ensuring superior performance under unfavorable grid conditions, such as overcurrent scenarios, is still a relevant area of research. Conventional grid-following (GFL) inverters can alleviate an overcurrent situation by simply putting a current limit. However, adapting the same for GFM inverters can exacerbate the situation by driving the system toward instability under certain conditions. To address this issue, a power angle limiting approach is discussed here which is suitably adapted for dVOC-controlled GFM inverters. Detailed analysis and the implementation of the method are discussed here along with supporting simulation results.",
