This invention provides A Network Distributed Dynamic Equalized Power Supply Method, with the steps shown as below that: multiple High Voltage Direct Current power supply devices deployed in parallel, the entire High Voltage Direct Current power supply devices parallel connected via the Direct Current Power Grid; there being four power supply modes pre-set in each device, the initial setting part being that the power supply mode of back-up High Voltage Direct Current power supply device being mode B, and the rest being mode A, further, the power supply voltage of the entire High Voltage Direct Current power supply devices to the Direct Current Power Grid being the same. As per the operation status of one certain High Voltage Direct Current power supply device or the change of power supply load, the power supply mode of the mentioned High Voltage Direct Current power supply device and the power supply voltage to the Direct Current Power Grid are changed. By adopting the above-mentioned technology plan, the distributed power supply could be conducted and networked, and the reliability of the Network Distributed power supply could be improved, in the meantime, the electric quantity of power supply could be flexibly adjusted and distributed among the different power supply devices, to improve the efficient of the utilization of energy and reduce the energy consumption.
