The connection of distributed generation increases the short circuit power which in turn might exceed the ratings of the installed circuit breakers. A solution is to limit the available short circuit power by increasing the grid impedance, but since there is a constant strive for lower losses and higher power transfer capabilities, this is not desired. The application of a fault current limiter (FCL)...
The influence of instantaneous voltage drops in the power systems due to lightning have become a significant issue, because manufacturing facilities have become highly sophisticated and intelligent. On the other hand, it may be impossible to completely avoid instantaneous voltage drops in power systems caused by natural phenomena. In order to solve the problem of the voltage drops, this paper presents...
