摘　　要：在光伏发电系统中,最大功率跟踪技术能够实现对能源的最大利用,但对于传统的MPPT控制算法,它存在稳定性差且无法实现对最大功率精确跟踪等缺点。为解决上述问题,提出了一种新型的光伏发电系统最大功率跟踪方法-反推法,它具有算法简单、易于工程实现、可保证整个系统全局稳定等优点。利用MATLAB/Simulink分别搭建了传统扰动观察法和反推法的仿真模型,仿真结果验证了反推法相较于扰动观察法输出波形平稳,波动范围小,且在扰动点过渡平滑的优越性。In the photovoltaic power generation system,the maximum power tracking technology can achieve the maximum utilization of energy,but for the traditional MPPT control algorithm,it has poor stability and cannot achieve the precise tracking of the maximum power. Based on this,this paper proposes a new type of photovoltaic power generation system maximum power tracking method-reverse method,which has the advantages of simple algorithm,easy engineering implementation,and global stability of the whole system. The simulation model of traditional disturbance observation method and backstepping method was built with MATLAB/Simulink respectively. The simulation results verify that the output method of the back - push method is smoother than the disturbance observation method,the fluctuation range is small,and the transition smoothness at the disturbance point is superior.
