Abstract

The invention provides a power supply system, a control method and a data center, and relates to the technical field of data centers. The power supply system comprises a commercial power supply branch which comprises a commercial power connection port and a first conversion unit, and the first conversion unit is used for adjusting output parameters of the commercial power supply branch; the photovoltaic power supply branch comprises a photovoltaic electric energy connection port and a diode; the first energy storage branch comprises a first battery port and a second conversion unit, the first battery port is used for being connected with the first battery unit, and the second conversion unit is used for adjusting at least one of input parameters and output parameters of the first energy storage branch; wherein the commercial power supply branch, the photovoltaic power supply branch and the first energy storage branch are connected in parallel to the output bus, and the output end of the output bus is connected with the load connection port. According to the technology disclosed by the invention, the power supply output quality of the power supply system is guaranteed, the mains supply usage amount of the data center is reduced, the carbon emission of the data center is reduced, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The present disclosure relates to the technical field of data centers, in particular to a power supply system, a control method and a data center. Background technique [0002] In related technologies, data centers usually use uninterruptible power supplies or high-voltage direct current transmission equipment as intermediate conversion equipment for cabinet power supplies. New energy sources such as photovoltaics need to be equipped with dedicated power conversion equipment, such as inverters, which are incorporated into the power supply system of the data center. With the increase of photovoltaic energy, traditional data center power supply equipment can no longer flexibly adjust the access ratio and quality of energy; and the current equipment has no fine-grained control of photovoltaic equipment grid connection, and is in a state of ready-to-use, which is not conducive to low-cost data centers run. Contents of the invention [0003] The present ...
