| Abstract: |
| The operating characteristics of traditional direct-driven PMSG（Permanent Magnet Synchronous Generator） and the control of FESU（Flywheel Energy Storage Unit） are analyzed and the power smoothing control without wind velocity measurement is proposed for the wind power system. The small signal model of control system is built up and the stability analysis shows the proposed control system maintains the stable operation of power system under the small disturbance conditions. Simulation is carried out for a PMSG system with FESU and results show that the proposed control strategy smoothes effectively the output active power fluctuation while ensures the maximal capture of wind energy. |
