摘 要:为了实现风光互补发电系统的最大功率点跟踪(MPPT),根据风能与太阳能的特性,采用双输DC/DC变换器作为前级电路,在扰动法的基础上提出自调整MPPT控制策略,有效改善了系统的跟踪速度,避免误操作,减小工作点的震荡,并提高了系统效率。针对逆变电源控制,把自动调节反馈系数的PID控制系统与重复控制系统相结合,不仅提出复合控制算法,使系统具有较好的动静态特性,且改善了逆变器输出波形的质量。

Abstract: In order to realize maximum power point tracking (MPPT) of hybrid photovoltaic-wind power generation system, dual input DC/DC converter was adopted as the forward circuit according to features of wind energy and solar energy. On the basis of disturbance method, the self-adjusting MPPT control strategy was raised to have effectively improved tracking speed of the system, avoiding misoperation, reducing vibration of working point and raising the system efficiency. As for inverter control, the PID control system for auto-adjusting feeding coefficient was combined with the repetitive control system. This paper not only raised the repetitive control algorithm, making the system have better static and dynamic characteristics, but also improved quality of inverter output waveforms.
Key words: hybrid photovoltaic-wind; maximum power point tracking; inverter; repetitive control
