具有串并联微型变换器的混合微电网

In this paper, a hybrid microgrid with series- and parallel-connected microconverters is proposed. A few series-connected low voltage microconverters are used to build a string converter with rated output voltage magnitude. Then, the parallel operation of string converters increases the power rating and redundancy of the microgrid. To realize both grid-tied and islanding microgrid control with pro...
