英文摘要：

The power flow calculation method with power system analysis software Package/user program interface（PSASP/UPI） is established,where the randomness of wind speed,the uncertainty of wind power generation,the impact of wake effect are considered.The user program interface（UPI） of wind farm model is composed,and the passed data with load flow（LF） calculation module through the interface are proposed by PSASP.The modules of UP and LF alternating iterative are calculated,thus the power flow calculation considering the wind turbine is implemented.The model proposed in this paper is connected to a single machine infinite bus system to verify the availability and reasonableness of the program.The power flow is calculated using the model connected to 3-machine 9-bus system,and the variation of nodal power flow before and after the connection of wind farms is analyzed and compared.Thus can provide a reference for power flow quantitative calculation under uncertainty of the wind power generation.
