Islanding Detection During Intended Island Operation of Nested Microgrid [PDF]
2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2018 In the future, functionalities like islanding detection must also operate during intended island operation of (MV+MV or MV+LV) nested microgrids. In this paper, healthy and faulty islanding detection of LV network connected generation unit during nested (MV+LV) microgrid islanded operation were studied by simulations with PSCAD model from real-life ...
