I. Introduction
Microgrids and their flexible control features propose a practical solution to employ better renewable energy resources by converter interface power electronics [1]. On the other hand, lack of synchronous generators in the converter interfaced microgrids (MGs) leave more operation-protection consequences. Though, low inertia of converter interfaced renewable energy sources (CIRESs) are introduced as a general drawback, they have fast controllable dynamics, which may be introduced as promising solutions for both power support and frequency response reaction [2].
