中文摘要: 针对目前MPPT方法中常用的扰动观察法的缺点,提出了一种自适应变步长算法,将其应用于并网系统仿真模型中.仿真结果表明,采用自适应变步长MPPT算法的系统在外界环境突变的条件下,能够准确、快速地跟踪最大功率点,且满足并网要求,并具有良好的动态及稳态特性.
Abstract:Aiming at the shortcomings of perturbation and observation method as used in M PPT method, a self-adapting variable step-size algorithm is proposed and applied to the simulation model of grid connected system. The simulation results show that the system using the self-adapting variable step-size M PPT algorithm can more accurately and rapidly track the maximum power point and meet the grid requirements and has good dynamic and steady-state characteristics under the condition of environmental mutation.
