Islanded microgrids are key for renewable energy and distributed energy management but face challenges in maintaining voltage stability and performance due to energy source volatility and external disturbances. To address this issue, this paper proposes a voltage control strategy based on a multi-intelligence coherence algorithm. First, various distributed energy sources in an islanded microgrid are modeled as a multi-agent system, with global voltage control achieved through local information exchange among the agents. Second, the Barrier Lyapunov function (BLF) is used to ensure that all states satisfy the constraints. An adaptive strategy using multi-agent consensus control is designed to ensure the microgrid inverter system's voltage amplitude tracks reference input signal changes. The effectiveness of the proposed strategy is verified by simulation experiments, and the results show that the strategy can effectively maintain voltage stabilization.
