| 摘 要： | 针对光伏发电系统最大功率点跟踪恒定电压法跟踪精度较低的缺点,提出了基于温度系数在线修正的改进恒定电压法与粒子群优化结合的光伏MPPT算法,即在系统偏离最大功率点时,采用改进恒定电压法快速确定一个新的工作点,再采用粒子群优化进行最大功率控制,使得MPPT确保跟踪速度的同时又提高了跟踪精度。最后通过Matlab/Simulink对该算法进行了仿真,结果表明该控制系统可快速跟踪最大功率点。

| Abstract: | In view of the poor accuracy of photovohaic system maximum power point tracking （ MPPT）, a new photovoltaic MPPT is proposed, which combines the improved constant-voltage method based on temperature correccoefficient online with particle swarm optimization point, a new operating point can be searched through algorithm. When the system deviates from the maximum power the improved constant voltage method quickly. With the help of PSO maximum power control, accuracy is improved at the same speed. Simulation of the method in Matlab/simulink shows that the system can search the maximum power point quickly. |
