摘　　要：针对独立光伏发电系统中最大功率点跟踪(MPPT)控制策略与蓄电池充电管理相冲突的问题,将超级电容器应用于光伏系统中,与蓄电池一起构成混合储能系统。根据其性能特点,将恒定电压法与自适应变步长电导增量法相结合,提出了改进型MPPT策略。仿真及实验结果表明,改进的方法能够快速、稳定及准确地找到最大功率点。Aiming at the conflict between MPPT control strategy and （storage） battery charging management, super capacitor was used in photovoltaic system to form the compose hybrid energy storage system with storage battery, according to their characteristics. An improved MPPT control strategy was proposed by combining constant voltage method and adaptive variable step-size conductance increment method. Simulation and experimental results have been reported to validate the improved MPPT control strategy could reach the maximum power point quickly, steadily and accurately.
