基于虚拟电阻的混合交直流微电网分布式双向DC-DC变换器二倍频纹波均流控制

The hybrid ac-dc microgrid, consisting of ac subgrid and dc subgrid, is a promising structure to interconnect ac and dc systems to provide high quality and reliable electric energy. However, in single-phase microgrid or unbalanced three-phase microgrid, second-order ripples of the dc subgrid can lead to significant power quality issues. The ripple mitigation function can be added to existing bidir...
