  • 摘要: 本文研究了分布式控制策略下直流微电网的负荷分配和电压平衡问题. 给出一种新的基于分布式策略的下垂控制器设计方法, 能够在统一的框架下实现直流微电网负载共享和电压平衡. 首先将直流微电网的负载共享和电压平衡问题转化为多目标优化问题, 其性能指标与微源的容量密切相关. 然后, 通过求解多目标优化问题获得实现负载共享和电压平衡的集中式控制策略, 并给出下垂控制器的设计方法. 为了降低系统的通信负担, 给出一种新的只需与邻居节点交换信息的分布式控制策略, 通过理论分析可知该分布式控制策略能够收敛到多目标优化问题的最优解. 最后, 通过对新能源汽车充换电站系统的仿真验证了本文提出的方法的有效性.
