Distributed Dual Objective Control of A Flywheel Energy Storage Matrix System Under Jointly Connected Communication Network

Abstract: This paper studies the distributed dual objective control problem of a heterogenous flywheel energy storage matrix system aiming at simultaneous reference power track-ing and state-of-energy balancing. We first prove that the solution to this problem exists by showing the existence of a common state-of-energy trajectory for all the flywheel systems on which the dual control objectives can be achieved simultaneously. Next, based on this common state-of-energy trajectory, the distributed dual objective control problem is converted into a double layer distributed tracking problem, which is then solved by the adaptive distributed observer approach. Simulation results are provided to validate the effectiveness of the proposed control scheme.
