Embodiment approach

[0084] The energy consumption of the MEC server includes static energy consumption and dynamic energy consumption. As long as the MEC server is running, static energy consumption will be generated. Dynamic energy consumption refers to the calculation energy consumption generated by the MEC server processing user service requests. Assume that each MEC server caches the w daily services required by the user, and the MEC server uses the maximum CPU speed to process the user's request. The total energy consumption of the mth server at any moment can be described as:

[0085]

[0086] in: represents the static energy consumption, represents the dynamic energy consumption, Indicates the total number of CPU cycles required by the MEC server to process services. beta m Indicates that the mth MEC server runs at the maximum speed f m (Number of CPU cycles per second) Energy consumption per unit cycle when processing business, β m =k m f m , k m The value of is related to ...

Abstract

The embodiment of the present invention discloses a DC energy supply method. In order to promote the development of the ubiquitous power Internet of Things, the present invention uses a renewable energy-oriented power packet dispatching system to supply power to MEC servers. On the one hand, it can realize green environmental protection, on the other hand The emerging method of transmitting electrical energy in power packets can achieve quantitative, real-time, and precise energy scheduling.

Description

technical field [0001] The invention relates to the field of electric power communication, in particular to a direct current energy supply method. Background technique [0002] Mobile Edge Computing (MEC) technology, as one of the key technologies of 5G communication and ubiquitous power Internet of Things, can greatly improve the user experience rate. The MEC server powered by the power grid may waste power when the user requests or unloading volume is low; in addition, some areas with weak power foundations are difficult to directly connect to the power grid. MEC servers are powered by diesel generators, which not only has low energy efficiency, High operating costs and large greenhouse gas emissions. Contents of the invention [0003] In order to solve the above technical problems, the embodiment of the present invention provides a DC energy supply method. In order to promote the development of the ubiquitous electric power Internet of Things, the present invention use...
