The standard deviation of traditional high-speed railway traction power supply dynamic power flow calculation method has a large deviation.In this paper,a dynamic power flow calculation of high-speed railway traction power supply based on improved crisscross optimization algorithm is proposed.Firstly,the output characteristics of traction power supply device are extracted,then the high-speed railway traction power supply is modeled,and based on the model of high-speed railway traction power supply,the calculation results of train traction and the driving plan are used as input.Finally,based on the improved crisscross optimization algorithm,the traction power supply system of high-speed railway is solved to realize the dynamic power flow calculation of high-speed railway traction power supply.The experimental results show that the standard deviation offset of the calculated method is smaller.
