Abstract: In order to coordinate the configuration capacity effectively in the power grid, the reliability of different modes of distributed multi-power source open-loop wiring is studied. The multi-power sliding mode controller is used to coordinate the current ratio between the distributed torques, and then the open-loop curvature of the motor structure is calculated. All the distributed nodes in the distribution network environment are reconstructed, and the specific value of the number of open-loop feeders is calculated according to the multi-stage optimization criteria, and the planning and connection mode design of the double-layer distribution network is completed. The experimental results show that the design of this mode has strong adaptability to power grid dispatching. Compared with the “one word” open-loop connection method, the grid capacity after applying the step-by-step two-phase hybrid connection mode is more than 100 TW·h. After the application of the double-layer distribution network planning and connection mode, the conductivity rate of the power grid can reach 90%, and the configuration capacity in the grid environment is properly coordinated, and the application reliability of distributed multi generation appears an obvious upward trend.
