Based on the Power Factors of DFIG Wind Farm for Power Flow Optimization

Double fed induction generators are able to operate on different power factors, and can be used to support power systems. On the basis of regulating the power factors of double fed induction generators, the wind power penetration conditions are taken into account; the hybrid artificial bee colony algorithm is proposed to calculate the optimal power flow, and the impact of different power factors on the power system is researched. In this chapter, the model of objective function is formulated to minimize the conventional generator cost under the consideration of various power factors of double fed induction generators. The simulation results show in high wind speed, double fed induction generators can regulate power factors to support power system operations and reduce the conventional generator cost, and the hybrid artificial bee colony algorithm is better for the converged speed of algorithm than the artificial bee colony algorithm. Thus, the model and new algorithm are proved effectively.
