In order to improve the energy consumption capacity of the power supply service process in the power system,a research on the design of distributed power grid connected power system dispatch automation control method considering high energy load is carried out.Based on the constant power factor operation mode of the high energy load power grid,balance the reactive power of the doubly fed machine in the grid.Assuming that the stator side power factor of the distributed power source remains unchanged,establish a distributed grid connected power system power model considering high energy load conditions.To reduce the waste of electrical energy resources,while considering scheduling fairness,the minimum wind abandonment is taken as the control objective,and a system scheduling control objective function is designed.Implement safety constraints on the scheduling process of the power system,and complete the design of automated control methods by controlling the minimum abandoned air volume.The experimental results of practical application demonstrate that the designed automation control method has good practical application effects.This method can effectively improve the absorption capacity of continuous nodes,improve the utilization rate of distributed energy in the power grid,and leverage the higher value and efficiency of the power system in regional power supply services.
