In the HBCS-MG system, unstable microsource output power causes operational issues. This paper proposes an SOC-weighted hierarchical control method based on dynamic event-triggered consistency conditions in multi-agent systems (MASs). The method connects adjacent sub-module energy storage parts in a ring topology to collect real-time battery capacity, establishes a compensation gain coefficient as a consistency coordination parameter, and coordinates sub-module energy storage output tasks to achieve adaptive power distribution, reducing in-phase output power differences and realizing coordinated control of battery output power. Simulation results demonstrate that the proposed consistency condition achieves in-phase power coordination, and the control method effectively reduces output power fluctuations.
