  In this paper we introduce a Leader-follower consensus protocol and study its
stability properties with and without communication delays. On the practical
side, we explore its application on coordinating a group of wind Double-Fed
Induction Generators (DFIGs) with integrated storage. To begin with, we
establish asymptotic stability of the consensus protocol by employing singular
perturbation theory. Subsequently, we establish asymptotic stability of the
protocol under communication delays using a Lyapunov-Krasovskii functional.
Lastly, we use the proposed protocol to design a methodology that can be
adopted by a fleet of state-of-the-art wind generators (WGs). The objective is
that the WGs selforganize and control their storage devices such that WF total
power output is tracking a reference while equal contribution from each storage
device is attained i.e equal power output from each storage. We demonstrate the
effectiveness of our results and the corresponding approach via simulations on
the IEEE 24-bus RT system.
