Distributed finite-time event-triggered current sharing and voltage control of DC microgrids.

This paper proposes a distributed finite-time event-triggered secondary control for islanded DC microgrids (MGs). The proposed controller can provide accurate current sharing and critical bus voltage regulation in finite time without the need for periodic communications. The finite-time feature improves the convergence speed and transient response of the secondary control while the event-triggered behavior reduces the burden on the communication network. The proposed secondary control scheme is validated in MATLAB/Simulink and HIL testbed utilizing OPAL-RT and Raspberry Pis. • The finite-time event-triggered secondary controller for a DC MG is proposed. • The critical bus voltage restoration and accurate current sharing are achieved. • MATLAB/Simulink and HIL simulation testbeds validate the proposed controller. • An improved transient response with reduction on communication burden is presented.
