In order to solve the problem that impedance of each line parallel system wind–solar–storage virtual synchronous machine(VSG) is inconsistent, resulting in power circulation between VSG, a multi-parameter collaborative adaptive control strategy for synchronizers microgrid based on neural network was proposed. Firstly, topology machine built, and VSG analyzed. Then, algorithm used realize adjustment parameter which improves uneven distribution influence circulation. Next, parameters multiple systems were configured. Finally, MATLAB2021a/Simulink model system, capacity under different scale conditions simulated The simulation results show when ratio VSG1 VSG2 1:1, active output 9000 W, reactive 7500 Var, realizes accurate distribution, 2:1, values are 12,000 W/6000 W 10,000 Var/5000 carried out according shows can effectively improve allocation accuracy, suppressing
