Application of immune response feedback for distributed small wind generate system

The output character of wind generate system (WGS) are non-linear and time-varying with the changing of wind speed. A high-efficiency maximum power point tracking (MPPT) method is very important to costly WGS. At present, in order to track the maximum power point (MPP), various MPPT control method have been proposed to gain MPPT of WGS. Normally, the MPPT control can be achieved by using the DC/DC circuit and conventional incremental conductance (IC) or perturbation and observation (PO), but the tracking efficiency is bad due to the libration range of output by using Buck or Boost DC/DC circuit is big. In order to improve the output dynamic character, the immune response feedback principle (IRFP) is proposed to use in MPPT for WGS in this paper due to immune system has a robust to against various foreign microbes. The simulation shows that the output libration range is diminished by using the IRFP, and the response speed is rapid during the MPPT course, and anti-jamming ability is improved.
