Abstract:
The present invention discloses a method and apparatus for photovoltaic DC direct-fed power generation based on controllable power supply. According to the present invention, the photovoltaic cells are directly connected to the DC microgrid, and the DC bus voltage is flexibly regulated by the controllable power supply in the DC microgrid to enable the photovoltaic cells to operate at the maximum power, thus eliminating the need for a DC interface converter when the photovoltaic cells are connected to the DC bus and reducing the cost and size of the distributed PV power generation system.
