[0076] as attached figure 1 As shown, the data center is composed of a scheduler, geographically distributed computing nodes, and a hybrid power supply system. The data center can be powered by solar panels or by a traditional grid. When the user's request reaches the scheduler, the scheduler intelligently assigns the task to the most suitable computing node for processing according to the solar energy output on each computing node, the electricity price and the remaining computing power of each time slot, so as to minimize the data The target for the total electricity cost of the center.
[0077] 1. Data center energy consumption model
[0078]Step 1.1 Energy consumption expression: The energy consumption calculation formula of each computing node processor in the data center is Among them, d jk Indicates the energy consumption of computing node j in the kth time slot, pc act Indicates the busy power of the compute node processor, Indicates the busy time of computing n...
