中文摘要：

针对光伏阵列在受到阴影遮挡时光伏发电系统总功率大幅下降的问题,采用分布式光伏阵列与光伏逆变器的群控方法,通过开关矩阵将多个光伏阵列与多台光伏逆变器相连,形成灵活多变的光伏发电网络拓扑结构,并根据该网络拓扑结构的工作原理,提出了相应的自适应遗传算法来实现分布式光伏阵列与光伏逆变器之间的群控管理.仿真及实验结果表明,光伏阵列受到阴影遮挡时,该算法使得光能的转换效率明显优于常规典型的分布式光伏发电方式,为有效利用光能提供了思路.

英文摘要：

For the problem that the total power of photovoltaic power system declines sharply, when the photovoltatic array is affected by the partial shading, the group control method was adopted to connect PV array and inverters by the switch matrix. The flexible topology structure of photovoltaic power generation network was formed. Then, the working principle of topology structure was introduced and the corresponding adaptive genetic algorithm to realize the group management between distributed photovoltatic array and inverters was proposed. The simulation and experiment results show that the convertion efficiency of optical energy used by the algorithm is much better than that of conventional distributed photovoltaic power for the shade of photovoltatic array, and providing a way for the effective use of optical energy.
