In accordance with the complex characteristics of the composition of AC and DC hybrid microgrid clusters and the trend of high-power electronization for source-net-load

we put forward an intelligent hierarchical control of AC/DC hybrid microgrid clusters based on the discrete consistency strategy

and researched the form and group-level coordinated control strategy of AC and DC hybrid microgrid clusters in detail. When the user’s needs change

the sparse communication network is constructed based on the multi-agent system

and distributed control is realized on the distributed equipment in the microgrids. The communication between adjacent agents saves communication time. Finally

the influence of communication delay on the convergence stability of the consistency algorithm is analyzed. Simulation results show that when the diagonal elements of the random matrix D are not zero

the communication delay will not affect the convergence of the consensus algorithm

but it will affect the form and time of the convergence. In addition

the multi-agent system can achieve ‘plug and play’ and maintain the stability of the AC-DC hybrid microgrids.
