摘要
针对太阳能光伏发电系统常用的最大功率点跟踪(MPPT)控制方法 -电导增量(INC)法进行了详尽的、深入的分析和研究,并总结了其优缺点。本文在传统的以功率电压斜率(dP/dV)为变步长参考曲线的电导增量法的基础上提出了一种新型的电导增量控制算法,即以|(dP/dV)/p|为变步长参考曲线的改进的电导增量法。首先从理论角度说明其改进的优越性,继而通过常用的熟知的Matlab/simulink进行系统仿真,得到改进的电导增量法的最大功率点跟踪曲线。通过对比实验结果,表明该新型的控制算法具有更优的系统动态响应特性和稳态特性。
This paper gives a detailed and in-depth analysis and research about the Incremental Conductance method-INC which is one of the most popular technology of maximum power point tracking(MPPT)control technology of the Solar photovoltaic power generation systems,and gets the advantages and disadvantages of it.A new type of the Incremental Conductance method was proposed based on the traditional variable step size method which depends on(dP/dV),and it is a improved method depends on|(dP/dV)/p|.First of all,the superiority is shown from the perspective of theory,and then the model is tested by using the commonly used Matlab/simulink software, Finally,getting the simulation curve.Comparing the experimental results,it can conclude that the improved method shows much better on the system dynamic response and steady state properties.
