Abstract
Clock drifts are a common phenomenon in distributed systems, such as microgrids (MGs). Unfortunately, if not accounted for, the presence of clock drifts can hamper accurate frequency restoration and power sharing in MGs. As a consequence, in our previous work, we have proposed a distributed secondary frequency control called generalized distributed averaging integral (GDAI) control that ensures an accurate stationary control performance in the presence of clock drifts. In the present work, we provide a tuning criterion for the GDAI control parameters that guarantees robust stability of a given equilibrium point of the closed-loop dynamics with respect to uncertain bounded clock drifts. We work with the non-linear microgrid model and hence obviate the need for linearization. Finally, our analysis is validated on an exemplary MG via simulation.
