Aiming at the defects of imperfect control mechanism of AC/DC hybrid microgrid,a power coordination control strat-egy in AC/DC hybrid microgrid is proposed.The power balance relationship of AC/DC hybrid microgrid under different operat-ing conditions is analyzed.The power coordination control strategy of AC/DC hybrid microgrid under the conditions of grid connection and island is designed.In the experimental stage,the simulation model of the whole AC/DC hybrid microgrid is es-tablished in MATLAB/Simulink to verify the effectiveness of the proposed control strategy.The results show that the pro-posed control strategy can effectively stabilize the power of hybrid microgrid.The simulation results further verify that the pro-posed model can be used as a reference to improve the stability performance of hybrid microgrid.
