    Abstract: In order to give full play to the collaborative grid-forming regulation capabilities of distributed resources in microgrids and achieve control objectives such as consistent stability of frequency and output voltage, as well as reasonable allocation of active power. Based on the droop control characteristics of networked systems, this paper proposes a distributed secondary coordinated control strategy based on a multi-agent consistency algorithm. This strategy facilitates communication and interaction among secondary controllers within distributed generation resources and is designed using a leader-follower consensus control framework, and achieves the global frequency and output voltage to consistently follow the leader,s target. Moreover, it takes into account the differences in the capabilities of generating units, achieving precise sharing and optimal allocation of active power among them. The simulation results substantiate the effectiveness of the proposed control strategy and elucidate the impact of the associated secondary control gains on the overall performance.
    Key words: distributed resource; microgrid; power sharing; distributed control; secondary control
