Protection Issues in Microgrids with Multiple Distributed Generation Units

Novel Dual-FCL Connection with Neuro-fuzzy controller for Adding DG to a Power Distribution Utility

“…When a fault occurs, the nature of these devices is such that the over current is automatically reduced or limited. Passive devices include series inductors [14], and superconducting fault current limiters [15], [16]. While series inductors are inexpensive and require low maintenance, they cause a voltage drop during steady state operation and have poor limiting performance compared to newer FCL topologies.…”

Study of Micro Grid Safety & Protection Strategies with Control System Infrastructures

“…One of the major challenges of micro grid protection system is that it must respond to both island and grid connected faults [1][2][3][4][5][6][7][8][9][10][11][12][13]. In the first case the protection system should isolate the smallest part of the micro grid when clears the fault.…”

Effect of DG on Distribution Grid Protection

“…Extensive research is done to address possible protection problems in distribution grids including distributed generation. For instance, in (Deuse et al, 2007;Doyle, 2002;Driesen & Belmans, 2006;Driesen et al, 2007;Hadjsaid et al, 1999;Kauhamieni & Kumpulainen, 2004) it is discussed that the following protection problems might appear:…”
