For islanded microgrids (MGs)

distributed control is regarded as a preferred alternative to centralized control for the frequency restoration of MGs. However

distributed control with successive communication restricts the efficiency and resilience of the control system. To address this issue

this paper proposes a distributed event-triggered control strategy for the frequency secondary control in islanded MGs. The proposed event-triggered control is Zeno behavior free and enables each DG to update and propagate its state to neighboring DGs only when a specific “event” occurs

which significantly reduces the communication burden. Compared with the existing event-triggered control

a trigger condition checking period of the proposed event-triggered control is provided to reduce the computation burden when checking the trigger condition. Furthermore

using the aperiodicity and intermittent properties of the communication

a simple detection principle is proposed to detect and isolate the compromised communication links in a timely and economic fashion

which improves the resilience of the system against FDI attacks. Finally

the control effectiveness of the proposed control scheme is validated by the simulation results of the tests on an MG with 4 DGs.
