With both AC microgrid and DC microgrid advantages

the AC-DC hybrid microgrid is a promising development form of a microgrid form in the future. Peer-to-peer control strategy of the islanded AC-DC hybrid microgrid has many distributed generators and distributed storage devices controlled by different methods. The peer-to-peer control strategy of islanded AC-DC hybrid microgrid power flow calculation model is established

which is based on interlinking converter scaling method of autonomous operation control strategy and the consideration of bidirectional power exchange between AC subsystem and DC subsystem. In order to improve the convergence of the existing power flow calculation methods

an improved trust region algorithm based on the trust region radius convergence to 0 is proposed. According to the comparison of the BFGS trust region algorithm and the Newton-Raphson method

the effectiveness and robustness of the proposed algorithm is verified by comparing the results of the 12-bus islanded AC-DC hybrid microgrid.
