...Demand-supply balance is critical in microgrids, and hence the intermittent nature of RES is particularly relevant in these systems [16]....
[...]
...In addition, a system blackout after large disturbances due to tripping of DERs, in particular inverter-based RES due to under-frequency and under-voltage protection schemes, are a serious concern....
[...]
...Another consequence of the microgrid small size is higher uncertainty in the system, due to the reduced number of loads and highly correlated and fast variations of available RES [3]....
[...]
...Depending on the system response and load characteristics, a voltage instability may occur following a large disturbance, such as a sudden change in the demand and/or output of RES, or a generator outage....

...Small signal stability and eigenvalue analysis of converter-fed microgrids that are controlled based on droop characteristics have also been reported in the literature [82], [85], [93], [94], concluding that the dominant modes of the closed loop system are determined by droop controllers, and the overall stability of the system mainly depends on droop control gains, system loading conditions, and network parameters....
