Abstract:

Considering the two-way regulation characteristics of the battery energy storage system,a regional power system automatic power generation control model including the battery energy storage system is established.The model tracks the predicted and actual frequency deviations based on the battery energy storage system.The principle of power distribution for frequency control makes the frequency of each area of the power system more stable.Using MATLAB/Simulink simulation analysis,it is verified that the proposed control strategy can realize real-time elimination of new energy grid-connected operation risks,effectively alleviate the pressure of two-way frequency modulation of traditional units,and the frequency of each area is more stable.This strategy has certain flexibility.
