A capable and cost-effective protection scheme is essential for the reliable operation of a microgrid. Conventional impedance measurement-based protection is hindered by shorter line

Microgrids are parts of the distribution network that can operate either in parallel with the main power system or, when required, as controlled islands [1]. Their structure differs markedly from conventional

First, three stability criteria based on impedance parameters are presented. Then, we present a new impedance measurement method for microgrids based on square wave current injection.

The resulting approach enables the detection of high-impedance faults as outliers from the normal operating states of microgrid lines with passive
