Multi-DC microgrid-based power supply system of green data center

Abstract

The invention discloses a multi-DC microgrid-based power supply system of a green data center. Power is supplied to the green data center by renewable energy sources such as a multi-DC microgrid, solar energy and wind energy. In the system, an architecture is a DC microgrid architecture, each unit is connected onto a 380V high-voltage DC bus, power exchange can be performed between a public grid unit and a DC microgrid, so that the power is supplied to the green data center, and power support is provided for energy storage of a storage battery in the system; a wind power generator, a micro-gas turbine and a photovoltaic cell are arranged on the high-voltage DC bus, the micro system provides green renewable energy sources, and meanwhile, a high-power AC-DC load is also connected onto the high-voltage DC bus; and each sub-DC microgrid in the system is connected onto the high-voltage DC bus through a converter, and a low-power AC-DC load and a storage battery energy storage and distributed power supply are arranged in each sub-DC microgrid. Therefore, a dynamic and flexible multi-DC microgrid power supply system of the green data center is formed by such structure.

Description

technical field [0001] The invention relates to a green data center power supply system. In particular, it relates to a system for powering green data centers using multiple DC microgrids. Background technique [0002] With the change of the world economic situation, the information industry and the electronic information industry are playing an increasingly important role. These two emerging industries are also called new growth points of the national economy in our country. The rise of the Internet has become a new economic growth point recognized by all countries in the world, and it is also a new commanding height of national comprehensive national strength. In order to seize this commanding height, all countries in the world are stepping up the development of industries with confidence building as the core. The data center is the foundation of the development of the Internet industry and the guarantee for the safe operation of the Internet. For the data center, the sta...

Problems solved by technology

However, distributed power generation, especially photovoltaic power generation and wind power generation, has high intermittency and randomness, and its stand-alone access cost is high and control is difficult. Compared with large power grids, it is an uncontrollable source. Therefore, large power grids Distributed power is often dealt with in a restricted and isolated manner, which will greatly limit the application and development of distributed power for a long time
