| Abstract: | In this paper, a new topology is proposed to achieve stable active output power of wind power systems, which can conveniently add the electrical double layer capacitor (EDLC) energy storage system to the DC side of the convertor. According to the analysis of the control strategy of dual PWM AC DC AC converter and the topology that connects the direct driven permanent magnet synchronous generator for wind turbines with the power grid, the control strategy is presented for stabilizing active output power of wind power system by using EDLC and releasing the active and reactive output power. The influence factors of stabilizing active power including the initial value settings of active output power and the size of EDLC capacity are discussed. For a typical wind condition, the initial value of active power output and the size of EDLC capacity are estimated. |
| Keywords: | direct driven permanent magnet synchronous generator for wind turbine electrical double layer capacitor control of output power control strategies decoupling control |
