摘要
针对光伏系统传统最大功率点跟踪(maximum power point tracking,MPPT)方法存在收敛速度慢、控制精度不足及易陷入局部最优解的问题,提出一种基于樽海鞘算法结合电导增量法改进的MPPT方法,利用樽海鞘算法的全局搜索和电导增量法的快速局部搜索优势,提升了系统动态响应速度及效率,避免局部最大化。通过静态对比和动态仿真试验,验证了该方法在追踪速度和精度上表现优异,且在复杂环境下具有良好鲁棒性。
In the field of photovoltaic system,the maximum power point tracking(MPPT)technology is faced with the problem of slow convergence,insufficient control accuracy and easy to fall into local optimum solution.It proposes an improved MPPT method combining the salp swarm algorithm(SSA)and incremental conductance method.The global search of SSA and the fast local search of incremental conductance method are used to improve the dynamic response speed and efficiency of the system and avoid local maximization.Through static comparison and dynamic simulation test,the method is proved to be excellent in tracking speed and accuracy and good robustness under complex conditions.
