资料介绍

针对局部阴影条件下光伏阵列输出效率低并且对最大功率点跟踪MPPT(Maximum Power Point Tracking)收敛速度慢的问题,设计出一种基于DSP的智能MPPT控制器。提出一种目标因子与过渡机制的改进蚁群全局寻优二阶段MPPT全局寻优算法作,引入目标导向因子避免盲目寻优,引入过渡机制而弥补寻优末期的振荡完成最大功率跟踪。通过仿真与实验的分析表明,改进后的算法在光照突变时具有较快的响应速度和较高的跟踪精度,避免系统趋于稳定时的功率振荡,提高了系统效率。

To solve the problem that local shadow under the condition of low efficiency of PV array output and the maximum power of the problems of slow convergence speed,design a kind of intelligent MPPT controller based on DSP.An improved ant colony global optimization two-stage MPPT global optimization algorithm with target factor and transition mechanism is proposed.The target steering factor is introduced to avoid blind optimization,and the transition mechanism is introduced to compensate for the maximum power tracking of the oscillation at the end of optimization.The simulation and experimental analysis show that the improved algorithm has faster response speed and higher tracking accuracy when the illumination is abrupt,avoiding the power oscillation when the system tends to be stable,and improving the system efficiency.Comparative analysis by simulation and experiment show that the improved algorithm contained higher tracking accuracy when the illumination is abrupt,avoiding the power oscillation when the system tends to be stable,and improving the system efficiency.
