This is a microgrid system.
According to the China Electric Power Bidding and Procurement Network data query, China Unicom’s data center is now a microgrid system. Many green energy-saving technologies applied in the data center are the first in China. Microgrid technology is applied in power. The backup oil generators of each building are formed into a power grid pool and can be used freely. This technology has also obtained a national invention patent.
Microgrid is a concept that is different from the traditional large power grid. It refers to a network composed of multiple distributed power sources and their related loads according to a certain topological structure, and is connected to the conventional power grid through static switches. It is developed and extended. Microgrids can fully promote the large-scale access of distributed power sources and renewable energy to achieve highly reliable supply of multiple energy forms to loads. It is an effective way to realize active distribution networks and transition traditional power grids to smart grids.
