针对光伏电池最大功率点随环境条件变化而发生漂移的问题,建立光伏电池的等效模型,采用PVsyst软件仿真光伏电池在不同光照及温度条件下的输出特性,利用Matlab/Simulink软件建立基于电导增量法的最大功率点跟踪(Maximum Power Pint Tracking,MPPT)仿真模型.仿真结果表明:基于电导增量法的MPPT控制方法,能使光伏发电系统在环境及负载变化情况下快速实现MPPT,且稳态精度高.

Aiming at the problem of the maximum power point of photovoltaic cell occuring shift with the change of environmental condition,builds the equivalent model of photovoltaic cell,adopts PVsyst software to simulate the output performance of photovoltaic cell under different illumination and temperature, based on conductance increment method using Matlab/Simulink software to establish maximum power point tracking(MPPT)simulation model. The simulation result shows that MPPT control method based on conductance increment method can fleetly realize MPPT of photovoltaic power generation system under the change of environment and load,and the precision of the stability is high.
