Research of intelligent control method for all-weather tracking photovoltaic system

针对光电池利用率低、光伏系统无法自适应多变的天气等缺陷,提出了跟踪型光伏系统全天候运行的智能控制方法。文章描述了环境与对象特征的获取方法,对全天候跟踪型光伏系统的控制策略进行了讨论,分析了太阳方位的跟踪控制方式。仿真试验表明,采用时钟定位法和光偏比较定位法相结合方式确定太阳位置的效果明显,能满足光伏系统跟踪控制的要求。

An intelligent tracking control method solve the problem of low solar cell utilization rate of photovoltaic power generation is put forward to caused by change of weather and other defects in all-weather operation conditions. The acquisition method of environment variables and the object fea-tures is described, the control strategies of tracking photovohaic system are discussed, and the sun lo-cation control method is analyzed. Simulation results show that the tracking algorithm is able to locate the sun accurately according with the tracking control requirements of photovohaic system.
