Microgrid offers many technical challenges despite of umpteen benefits. Protection is one of them which requires more attention. Protection of microgrid system is essential for reliable and economic operation. The protection scheme must be proficient in handling any type of fault without disturbing the entire framework.
Moreover, the proposed scheme in [25, 26] used the coordinate control technique to supply the virtual inertia for VSG to analyse and enhance the transient and steady-state performance of microgrid. It is discussed in [ 27 ] …
