本发明涉及种新型能量转换系统，包括输入端连接到上级电网的双向整流器及输出端连接到下级电网的双向逆变器，所述双向整流器的输出端和双向逆变器的输入端分别连接到直流母线，所述直流母线连接到储能装置。本发明还提供种新型能量转换方法。本发明通过双向整流器和双向逆变器实现了上下级电网间的能量转换，可为微电网提供"主干网"，使得微电网的构建不必依赖于大电网的容量。 The invention relates to a novel energy conversion system which comprises a bi-directional rectifier whose input terminal is connected to an upper level power grid and a bi-directional rectifier whose output terminal is connected to a lower level power grid. An output terminal of the bi-directional rectifier and an input terminal of the bi-directional inverter are connected to a direct current bus respectively. The direct current bus is connected to an energy storage device. The invention also provides a novel energy conversion method. According to the system and the method, through the bi-directional rectifier and the bi-directional inverter, the energy conversion between the upper power grid and the lower power gird is realized, a 'backbone grid' is provided for a micro power grid, and the construction of a micro power grid is not de
