[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples.
[0020] figure 1 It is a schematic diagram of the overall structure of the present invention, the energy storage module 3 is connected in parallel to the DC bus side of the power electronic conversion module 4, the AC side of the power electronic conversion module 4 is connected to the low voltage side of the transformer T2, and the high voltage side of the transformer T2 is connected to the power grid. The energy storage module 3 is composed of M composite energy storage units 5 . The power electronic conversion module 4 adopts the multiplexing technology and is composed of N power electronic converters 6 . The number M of the composite energy storage units 5 and the number N of the power electronic converters 6 are determined according to the load capacity of the user side. Transformer T2 adopts staggered phase technology, and the wiring mode ...
