| 摘 要： | 光伏电池工作效率的高低取决于其控制系统采用的控制方法。为了更好地节约资源,提高效率,该文提出了一种新的控制方法:首先控制系统的初始电压设置在某一近似点,然后根据控制系统采样数据进行循环插值计算,最后结合自循环的INC法实现快速查找MPP点,并稳定运行于此状态下。经过仿真试验和检验,确定此方法在外界条件变化时,能够使系统快速跟踪并工作在MPP点,提高了系统的工作效率。

| Abstract: | The efficiency of PV battery depends on its control method adopted in the system,in order to save resources and improve efficiency,This paper presents a new control method：first of all,the initial voltage of the control system is set in a similar point,and then based on sampled data of the control system for circular in- terpolation calculation,finally combining INC method to achieve fast lookup of MPP point.and stable running in this state.After simulation test and inspection,to determine when external conditions change,this method can make the system fast track and working at the MPP point,improve the work efficiency of the system. |
