摘　　要：在光伏系统中,提升光伏发电效率的同时减少成本,降低风险是研究光伏发电机组系统过程中需要注意的一个问题。因此该文提出一种基于滑模控制的最大功率跟踪点,配合双闭环控制的策略,来迅速并实时的使得直流母线电压稳定,减少蓄电池损伤的可能性。并在Matlab/Simulink中进行了仿真,验证该策略对光伏系统中蓄电池的控制成果,证明了仿真模型的准确性以及关于蓄电池管控的可行性。In the photovoltaic system,improving the efficiency of photovoltaic power generation while reducing costs,reducing risks is a problem we need to pay attention to which in the process of studying the photovoltaic generator system.Therefore,this paper proposes a sliding mode control based on the maximum power tracking point,combined with the double closed loop control strategy,to quickly and real-time dc bus voltage stability,reduce the possibility of battery damage.The simulation was carried out in Matlab/Simulink to verify the control results of the battery in the photovoltaic system by this strategy,and the accuracy of the simulation model and the feasibility of the battery management and control were proved.
