摘　　要：针对传统最大功率点跟踪算法无法兼顾追踪速度和稳态振荡的问题,提出1种步长可变的改进电导增量法。该改进电导增量法使用分区变步长提高最大功率点追踪速度,同时利用不完全偏微分理论优化稳态振荡的问题,提高了光伏发电的效率。通过将传统控制算法和改进电导增量法进行对比分析,验证了改进电导增量法的可行性和有效性。An improved incremental conductance method with a variable step size is proposed to solve the problem that the traditional maximum power point tracking(MPPT)algorithm cannot strike a balance between the tracking speed and steady-state oscillation.The MPPT speed can be increased by the improved incremental conductance method using a zonal variable step size.Meanwhile,the steady-state oscillation problem is optimized by using the incomplete partial differential theory,thus improving the efficiency of photovoltaic power generation.The feasibility and effectiveness of the improved incremental conductance method is verified by comparing the traditional control algorithm with the improved incremental conductance method.
