To obtain optimal power flow（OPF） of power system with wind turbine generator system,seeker optimization algorithm（SOA） is used for the solution.By analyzing the steady-state mathematical model of wind generator,the active power and reactive power expressions of asynchronous wind turbine generators are obtained according to power conservation principle.Wind turbine generators are treated as static joints in voltage because of their distinctive characteristics.Integrating with economy and security,the OPF optimization objective function is established,which consists of power loss and static voltage stability margin.SOA is adopted in solving this new OPF model in terms of the corresponding calculation process.The calculation result shows that the proposed model and algorithm are feasible.
