基于MATLAB的光伏MPPT仿真研究

Simulation research on maximum power point tracking control for photovoltaic system by MATLAB

基于光伏电池的工程模型,利用MATLAB中的simulink模块,建立光伏电池的近似模型,并仿真出不同温度下的光伏电池输出特性.仿真结果表明,该模型能够快速响应光照强度变化.当光照强度突变时,能够快速实现最大功率跟踪.

Based on simulation mode1 of photovoltaic cell,the output characteristic of photovaltaic cell was simulated at different temperatures with simulink blocks of MATLAB.A pratical model for photovoltaic block was developed.Simulations results show that the PV model can respond to the changes of insolation level quickly.When insolation level changes,it can quickly achieve maximum power point tracking and achieve good results.
