Power flow calculation for power system including offshore wind farm

This paper proposes a simplified steady-state equivalent model of asynchronous generators. With regard to the relationship between the wind velocity and generator's active power, terminal voltage, reactive power, as well as the slip ratio, a method to calculate the power flow for power system including large-scale offshore wind farm is then proposed, using the DLL files called by UPI of PSASP. The feasibility of this model is finally validated through the WSCC 9 node system included in PSASP and the comparison between the newly outcomes and the result from the existed calculation of power flow for power systems including wind farm.
