摘要
为提高光伏发电系统的最大输出功率,根据光伏电池的特性,针对中小型光伏发电系统的应用实际,提出了一种新型的MPPT控制方法和改进的恒定电压法,并在Matlab环境下进行仿真验证。分析与仿真结果表明,与常规CVT法相比,该方法能够有效提高最大功率点的追踪精度。
In order to improve the maximum output power of a photovoltaic （PV） cell,an improved CVT algorithm is put forwarded for the reality of application in medium and small size photovoltaic system in connection with the property of photovoltaic cell. The method is emulated by MATLAB simulation. Analysis and simulation results show that the method can improve the precision of MPPT effectively compared with the normal CVT algorithm.
