Current-Limiting Droop Control of Grid-Connected Inverters [PDF]
IEEE Transactions on Industrial Electronics, 2017 A current-limiting droop controller is proposed\ud for single-phase grid-connected inverters with an\ud LCL filter that can operate under both normal and faulty\ud grid conditions. The controller introduces bounded nonlinear\ud dynamics and, by using nonlinear input-to-state stability\ud theory, the current-limiting property of the inverter is ...
