This utility model relates to the field of
integrated energy system technology and discloses a multi-port adjustable photovoltaic-storage-DC-flexible integrated energy power supply
system. It includes a 750V
DC bus platform, a
photovoltaic power generation unit, a grid input terminal, a V2G charging
pile, an
energy storage unit, and a control cabinet cluster. The
photovoltaic power generation unit includes a photovoltaic array, an
MPPT controller, and a photovoltaic DC combiner box with a DC 750V output. The
photovoltaic power generation unit is electrically connected to the 750V
DC bus platform. The control cabinet cluster includes control cabinet one, control cabinet two, and control cabinet three. This utility model, through a multi-port DC power
router architecture combined with
intelligent control strategies, reduces AC / DC conversion links, significantly reducing
energy loss, improving the overall energy
utilization rate of the
system, achieving energy complementarity and optimized configuration, enhancing the
system's power supply capacity in
emergency situations, and improving the reliability and stability of the power supply.
