摘要
在外界环境迅速变化时,传统的电导增量算法(INC)动态性能和稳定性较差。为解决此问题,提出一种改进INC算法,使用Boost变换器的特性,快速定位最大功率点。利用Matlab/Simulink仿真软件,搭建MPPT仿真模型,并将改进INC算法与传统INC算法进行仿真对比。结果表明,此算法相较传统INC算法在跟踪速度和控制精度方面均有提升。尤其在追踪速度方面,改进INC算法比传统INC算法加快了5倍;跟踪精度高,比传统INC算法提高了5.98%。
Under the rapid change of environment,the conventional incremental conductance(INC)algorithm has poor dynamic performance.To solve the above problem,this paper proposes a modified INC algorithm that uses the characteristics of boost converter to quickly locate the maximum power point.The simulation model of maximum power point tracking(MPPT)system is built on Matlab/Simulink,and the simulation results of the modified and conventional INC algorithm are compared.Simulation results show that the modified INC algorithm has the improvement in tracking speed and control accuracy compared with conventional INC algorithm.Especially in terms of the tracking speed,the proposed algor ithm is 5 times.
