A New Event-Triggered Consensus Control for Microgrids

This paper studies an adaptive event-triggered consensus problem for heterogeneous multi-agent systems considering the time delay of the communication network. An event-triggered interval is here considered as a specific delay and unified round trip time (RTT) delay. Furthermore, an efficient optimal predictive-based coordination control strategy is introduced for balancing the non-ideal behaviors of communication channels. The efficiency of the proposed method for controlling network-based multi-agent systems with coupled subsystems is evaluated in two stages. In the first stage, the very method is implemented on two coupled continuous stirred tank reactors while in the second one, it is used to control the voltage and current of a DC microgrid consisting of several distributed generation units. To prevent the unessential utilization of communication resources, the transfer of information does not occur in this mechanism unless a specific event is triggered. The simulation results show that despite being non-ideal and time-delayed communication channels, the proposed technique is capable of improving the performance of power grids.
