Description

technical field [0001] The invention relates to energy consumption management of a data center, and more specifically, to a method for calculating operating costs in a data center using wind energy and battery energy storage. Background technique [0002] At present, with the rapid development of cloud computing technology, data centers, as an important part of cloud services, are under increasing pressure. Correspondingly, the power consumption inside the data center continues to rise. Inside the data center, there are a large number of servers, which will generate a lot of heat while the servers are operating. Therefore, it is necessary to use a computer room air conditioning (CRAC) to cool down the server. During the cooling process, a large amount of electric energy is also consumed, thereby generating a large amount of electricity expenses. [0003] On the other hand, the development of smart grids at home and abroad is also getting faster and faster. Some regions in ...
