中文摘要: 通过分析太阳能光伏发电系统的工作特征和现有的最大功率点跟踪(MPPT)方法,提出了一种基于遗传模拟退火算法的光伏发电系统MPPT方法.该算法将遗传算法和模拟退火算法相结合,通过将局部搜索过程引入遗传算法,从而使两种算法的搜索能力得到互相补充.针对某光伏发电系统的MPPT问题,通过仿真,将遗传模拟退火算法和遗传算法进行比较.仿真结果显示,遗传模拟退火算法和传统的遗传算法相比,能更快速、精确地跟踪到光伏系统的最大功率点.
Abstract:By analyzing the working characteristics of the solar photovoltaic power generation system and the Power Point Tracking Maximum (MPPT) method,a new MPPT method based on genetic simulated annealing algorithm is proposed.The algorithm combines genetic algorithm and simulated annealing algorithm,and the local search process is introduced into genetic algorithm so that the search ability of the two algorithms is complementary to each other.For the MPPT problem of a photovoltaic power generation system,through simulation,the genetic simulated annealing algorithm results are compared with the simulation results of genetic algorithm.The simulation results show that compared with the traditional genetic algorithm,the genetic simulated annealing algorithm can track the maximum power point of the PV system quickly and accurately.
