Distributed Active Power Sharing Control for Hybrid Microgrids With Dynamic Event-Triggered Strategy

In this paper, the issue of active power sharing between hybrid microgrids is investigated. A series of microgrids are linked through interlinking converters(ILCs). A dynamic event-triggered distributed approach is proposed, in which each ILC is counted as an agent that only needs update and broadcast at its triggered time instants. Different from traditional event-trigger, the proposed approach involves internal dynamic variable which ensures the system does not involve Zeno behavior. In this approach, the active power is indirectly regulated by a cooperative scheme, so as to achieve the proportional sharing of active power between hybrid microgrids. The simulation results prove the effectiveness of proposed control approach.
