Optimal Protection Coordination of Active Distribution Networks With Synchronverters
IEEE Access, 2022 Synchronverters are inverters imitating synchronous generators (SGs) to curb adverse impacts of traditional inverters on power networks. However, synchronverters may generate unlimited currents during faults.

Placement optimization of Multi-Type fault current limiters based on genetic algorithm
Global Energy Interconnection, 2021 The fault current limiter (FCL) is an effective measure for improving system stability and suppressing short-circuit fault current. Because of space and economic costs, the optimum placement of FCLs is vital in industrial applications. In this study, two

Comparison of current-limiting strategies during fault ride-through of inverters to prevent latch-up and wind-up [PDF]
, 2013 Transient stability of a power network requires that generators remain synchronized and return to normal power export once a fault is cleared. For inverter-interfaced generators, one must ensure that current and voltage limiters do not latch-up and that ...
