Distributed access control of volatile renewable energy resources

In this paper, we develop a general framework of distributed access control which allows for anytime connections and disconnections of volatile renewable energy resources in the power grid. We formally prove that the hard state constraints are satisfied all the time and the asymptotic stability is reached if connections and disconnections only happen for a finite number of times. Our framework and analysis leverage the tools of input-to-state stability and small gain theorems in nonlinear systems. The performance of our framework is illustrated by a case study on frequency control with wind integration.
