Embodiment 1
[0061] according to Figure 4 As shown, port 1 is equipped with an energy storage battery. When the electricity price is low, the first power module 1 is set as a bidirectional AC / DC module, the second power module 2, the third power module 3, the fourth power module 4, and the fifth The power module 5, the sixth power module 6, the seventh power module 7, the eighth power module 8, the ninth power module 9, the tenth power module 10, the eleventh power module 11 and the twelfth power module 12 are unidirectional AC / DC power conversion module, the bidirectional AC / DC module fully charges the energy storage battery. When the electricity price peaks, the energy storage battery releases the electric energy to the AC bus through the bidirectional AC / DC module, and the electric energy released to the AC bus can be passed through the second The power modules 2 to 12th power modules 12 and the automatic power distribution unit PCU charge the electric vehicles at other ports again, an...
Embodiment 2
[0064] according to Figure 5 As shown, port 1 is equipped with photovoltaics. When there is solar energy, the electric energy generated by photovoltaics can be distributed to other ports to charge electric vehicles through the PCU. The first power module 1 can also be set as a bidirectional AC / DC module, and the second power Module 2, third power module 3, fourth power module 4, fifth power module 5, sixth power module 6, seventh power module 7, eighth power module 8, ninth power module 9, tenth power module 10 . The eleventh power module 11 and the twelfth power module 12 are unidirectional AC / DC power conversion modules, which release the electric energy generated by photovoltaics to the grid or AC bus to supply power to other loads through the bidirectional AC / DC module;
[0065] When the power conversion module of a certain port is a bidirectional AC / DC module and is equipped with energy storage batteries and photovoltaics, the photovoltaic power generation can be used to...
Embodiment 3
[0067] Such as Figure 6 As shown, port 1 is equipped with energy storage battery + photovoltaic. When the electricity price is low, the first power module 1 is set as a bidirectional AC / DC module, the second power module 2, the third power module 3, the fourth power module 4, The fifth power module 5, the sixth power module 6, the seventh power module 7, the eighth power module 8, the ninth power module 9, the tenth power module 10, the eleventh power module 11 and the twelfth power module 12 are The one-way AC / DC power conversion module fully charges the energy storage battery through the two-way AC / DC module. When the electricity price peaks, the energy storage battery releases the electric energy to the AC bus through the two-way AC / DC module, and the electric energy released to the AC bus can be The electric vehicles at other ports are charged again through the second power module 2 to the twelfth power module 12 and the automatic power distribution unit PCU. When the ba...
