摘　　要：针对光伏发电系统中太阳能最大功率跟踪点(MPPT)算法的不足,基于插值计算法和变步长滞环比较法结合,提出了改进算法。该算法有效克服了传统MPPT算法中存在的误判与震荡现象,并提高了算法的精度和跟踪速度,在Matlab/Simulink下进行MPPT控制算法的建模与仿真,仿真结果表明,该算法有效提高了系统的动态响应速度和稳态精度。For photovohaic power generation system of solar energy maximum power point tracking （MPPT） algorithm is proposed based on interpolation calculation method and variable step length hysteresis comparison method combined with improved algorithm. The algorithm effectively overcomes the misjudgment and shock phenomenon existing in the traditional MPPT algorithm, and improves the accuracy of the algorithm and the tracking speed, under the Matlab/ Simulink MPPT control algorithm of modeling and simulation, the simulation results show that the proposed algorithm can effectively improve the system dynamic response speed and steady-state accuracy.
