Abstract
In order to meet the requirements of accuracy,time and convergence speed of power flow calcu-lation,a time series power flow calculation method for wind power storage interconnected integrated energy system is proposed.According to the operation structure of wind power storage interconnected integrated en-ergy system,the time series power flow models of energy conversion equipment and energy Internet are es-tablished respectively.Newton Raphson method is used to design the solution flow of the system time series power flow model,and realizes the time series power flow calculation of the wind power storage interconnec-ted integrated energy system.The structure,coupling element parameters and power flow values of the ex-perimental wind power storage interconnected integrated energy system are determined.The analysis results show that the research method calculates the system time series power flow iterations for 6 times,which takes 20ms,and the error of the system time power flow value is less than 0.1,which can meet the require-ments of system power flow calculation time,accuracy and convergence speed.
