Aimed at the problems of low accuracy and poor error compensation capability of the proposed distribution network dispatching model,a new integrated automatic dispatching model for distribution network is proposed based on distributed pow-er generation.At the same time,the wind power probability model and the output probability model are established,and the wind power output is calculated by strengthening the Gaussian mixture distribution function.According to the power grid peak times and node voltage amplitudes,the system network loss is obtained,the objective function is established,and the optimal control is carried out through the constraints.After the fuzzy set of the objective function is obtained,the scheduling model is established,and used to implement optimal scheduling.The experimental results show that the new integrated automatic scheduling model of distribution network based on distributed power supply has excellent convergence stability,higher schedu-ling accuracy,the network loss during the scheduling process is reduced by more than 50％,and the node expectation value is always above 0.98 pu,which has high feasibility.
