Abstract
Power buffers can help improve the inertia in DC microgrids and supply the additional power demand during short load transients. This article investigates distributed event-triggered control of power buffers over an unreliable network, subject to packet losses and transmission delays. For each power buffer, a distributed event-triggered control law regulates the input impedance while altering its stored energy. Moreover, a dynamic event-triggered communication mechanism determines the time sequence of control updates and data transmissions among power buffers. An appealing feature of this mechanism is a designable positive minimum inter-event time despite packet losses and transmission delays. The closed-loop system is shown to be exponentially stable. Controller/hardware-in-the-loop studies validate the theoretical findings.
