Abstract:With the wide access of distributed energy to power grids, the transition from traditional distribution systems to park-level information physical multi-microgrid is promoted. Aiming at the problem of power interaction between subnets after distributed resources are connected to the AC/DC hybrid microgrid, this paper proposes an resilience coordinated control strategy of multi-park end network considering autonomy and mutual benefit to ensure the power quality of the park system under the island. Firstly, considering the net power and the maximum transmission power of the sub-grid as constraints, the sub-grid is divided into three operation modes: autonomous, excessive and mutual. According to different modes, the charging and discharging rules of energy storage and the transmission direction of mutual power are designed, and the specific switching strategy is given. Then, the power quality of critical load (CL) is considered at the load side, and the backstepping control is applied to keep the expected trajectory of CL voltage stable for the power spring. Aiming at the problem of blocked information network communication, a distributed consistency model predictive compensation control method is proposed. Finally, the effectiveness and accuracy of the proposed control strategy are verified on the Matlab/Simulink simulation platform.
