Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power station and data center linkage processing, and specifically, to a joint scheduling method for power station and data center based on grey wolf optimization algorithm. Background Art
[0002] A data center is a basic hardware facility for storing and running data. During the normal operation of a data center, a large amount of heat is generated. If the temperature of the data center cannot be well controlled, it will affect the normal use of the data center. Therefore, it is necessary to perform heat dissipation adjustment on the data center. Currently, an important technical solution for realizing heat dissipation adjustment of the data center is to use water flow for heat dissipation. With the relatively low operating cost and relatively high heat dissipation capacity of using water flow for heat dissipation, many data centers are built underwater, that is, the so-called underwater data centers. Underwater data centers can use natural water flow or artificially formed water flow for heat dissipation.
[0003] In order to use water flow to dissipate heat from the data center, most of the existing technical solutions are to build the data center underwater, and do not use the water flow generated by a power station (generally referring to a pumped-storage power station) for heat dissipation. That is, the prior art does not combine the pumped-storage power station and the data center to achieve heat dissipation adjustment of the data center, and when achieving the purpose of heat dissipation adjustment, it can also control the power generation process of the power station, that is, there is no method for jointly scheduling the existing power station and the data center.
[0004] The following deficiencies exist in the independent operation mode of the pumped-storage power station and the underwater data center:
[0005] 1. Due to the lack of coordinated control with heat dissipation requirements, it is difficult to further improve the utilization efficiency of the pumped-storage power station for energy (here referring to water and related power generation equipment).
[0006] 2. Only using natural flowing water or artificially formed fixed water flow, the heat dissipation method of the data center is single, and the requirement for the stability of the water flow speed is relatively high, and it is difficult to dynamically adjust the cooling demand for heat dissipation.
[0007] 3. The pumped-storage power station and the data center lack a joint scheduling mechanism, and it is impossible to effectively balance the energy storage efficiency, power generation power of the pumped-storage power station and the cooling stability and heat dissipation performance of the data center.

Brief Description of the Drawings
[0042] Figure 1 It is a flow schematic diagram of the present invention. Detailed Embodiment
[0043] The following further describes the present invention in combination with the drawings and specific implementation schemes:
[0044] As Figure 1 shown, a joint scheduling method for a power station and a data center based on the grey wolf optimization algorithm. The power station is a pumped - storage power station, which includes an upper reservoir, a lower reservoir, a generator set and a water conveyance system. There is a height difference between the locations of the upper reservoir and the lower reservoir, and the lower reservoir is located below the upper reservoir. The water conveyance system is used to discharge the water in the upper reservoir into the lower reservoir and pump the water in the lower reservoir to the upper reservoir. The generator set is used to send the water in the upper reservoir into the lower reservoir, and convert the potential energy brought by the height difference of the water flow into electric energy to achieve power generation. The data center is located underwater in the lower reservoir.
[0045] The joint scheduling method includes the following steps:
[0046] Step 1: Calculate the optimal objective solutions of the energy storage parameter E stored , the power generation parameter P out , the cooling water flow parameter V cooling , the water flow stability V flow and the heat dissipation capacity Q thermal respectively based on the grey wolf optimization algorithm. The energy storage parameter E stored characterizes the energy storage efficiency of the pumped - storage power station in the pumping mode.

Cooling water flow parameter V cooling Characterize the stability of the water flow in the surrounding area where the data center is located, that is, the stability of the water flow used to cool the data center and within a preset range. The stability of the water flow can be quantified by a level to determine a specific value. The purpose of the stability of the water flow is to enable the data center to dissipate heat efficiently and stably. Water flow stability V flow Characterize the stability of the water flow velocity during the pumping and discharging processes of the pumped-storage power station, and its specific value can be obtained by level quantification. In the pumping mode, the more stable the water flow velocity, the more stable the load of the water pump in the water conveyance system, the smaller the energy loss, and the higher the energy storage efficiency, that is, the energy storage parameter E stored The larger. In the discharging mode, the fluctuation of the water flow velocity may cause the unstable operation of the water turbine in the generator set, thereby affecting the power generation parameter P out , that is, affecting the output of the power generation power. The water flow fluctuation will also be transmitted through the cooling water flow (reflected by the cooling water flow parameter V cooling ) system, and thus indirectly affect the heat dissipation performance of the data center. Heat dissipation capacity Q thermal Characterize the heat dissipation capacity of the data center, and a specific value can be obtained by quantification.

[0070] In the formula, X(t) represents the position vector of the current (i.e., the t-th generation) grey wolf, X(t + 1) represents the position vector of the (t + 1)-th generation grey wolf, t ≥ 0. When t = 0, X(0) is the initial position of the grey wolf in the grey wolf group, and the initial position can be randomly generated.
