Definitions

  • the invention relates to a method for operating a data center on an electrical network, as well as a data center which is set up to carry out such a method.
  • Such a data center can be operated as a consumer on an electrical network, which can be at least partially fed by volatile power generators as sources of electrical power.
  • volatile power generators can in particular be assigned to so-called regenerative energies, which can be photovoltaic or wind power plants, for example. What these volatile power generators have in common is that the electrical power generated fluctuates over time due to uncontrollable external influences. For a stable operation of the electrical network it is therefore necessary to provide control power. This leads to increased costs associated with the operation of such an electrical network.
  • Lalle have become known in which certain consumers have been disconnected from the network with a short warning period by an operator of such a network or have been throttled with regard to the power that they were allowed to use.
  • the invention is based on the object of a method for operating a data center on an electrical network and a data center for implementing such a network To create a method, wherein the disadvantages mentioned are at least reduced, preferably do not occur.
  • the object is achieved in particular by creating a method for operating a data center on an electrical network, which is also referred to as a power network.
  • a number of calculation tasks are processed by the computer center.
  • Each calculation task of the plurality of calculation tasks is assigned at least one parameter selected from a prioritization value and a calculation effort; or at least one parameter selected from the prioritization value and the calculation effort is assigned to each calculation task of the plurality of calculation tasks.
  • the calculation tasks are processed taking into account their respective at least one characteristic variable and a power supply parameter of the electrical network.
  • the data center can thus advantageously be included in the stability control of the electrical network, preferably without the risk that computation tasks that are urgently to be processed cannot be processed.
  • the processing tasks can advantageously be processed in such a way that the power generators assigned to the electrical network are operated with a high, preferably as high an efficiency as possible.
  • Both parameters that is, prioritization value and calculation effort, are preferably taken into account.
  • An electrical network is understood here to mean, in particular, a network for supplying electrical power or energy, in particular the electrical network is an electrical energy supply network.
  • the electrical network can be a AC voltage network or a DC voltage network.
  • the electrical network can in particular be designed as an island network. It is particularly possible that only the data center is operated as the only consumer on the electrical network. The electrical network is then assigned to the data center, as it were, as a separate network. However, it is also possible for the electrical network to be designed as an island network, with other loads being connected to the electrical network in addition to the data center. Alternatively, however, it is also possible for the electrical network to be designed as an interconnected network or a supra-regional network.
  • a calculation task is to be understood in particular as an order for the calculation or processing of data by the computer center. Such a calculation task is also referred to as a task. Such a calculation task can also be a partial calculation task of a superordinate overall calculation task.

  • such a prioritization value can be specified by a customer or client of the data center.
  • a calculation effort is understood to mean, in particular, a time and / or energetic effort associated with processing the calculation task and / or an - possibly virtual, i.e. computational - cost effort associated with the processing of the calculation task.
  • the computation effort can be a number of computation steps required to process the computation task, or the computation effort can depend on the number of computation steps required to process the computation task.
  • the prioritization value and / or the calculation effort can be specified by a client or customer of the data center, or they can be ascertained or determined before the start of the method proposed here.
  • a processing task is a prioritization value and / or a calculation effort at the point in time assigned to the implementation of the procedure.
  • a prioritization value and / or calculation effort - in particular from the computer center - is determined or specified for a processing task at the time the method is carried out. In this case, the prioritization value and / or calculation effort is assigned to the processing task.
  • a power supply parameter is understood in particular to be a parameter that characterizes a — current or future — state of the electrical network and / or of a power generator assigned to the electrical network.
  • processing tasks take into account their respective prioritization value and / or processing effort, and taking into account the

In particular, it is preferred to specify which calculation task is processed by the computer center and at what point in time.
  • Power provision parameter is a network stability parameter. This advantageously enables the data center to be integrated into the stability control of the electrical network.
  • calculation tasks with a higher prioritization value and / or lower calculation effort calculation tasks with a lower prioritization value and / or higher calculation effort are also calculated if the network stability parameter indicates that more power must be drawn from the network to stabilize the electrical network; that is, in the electrical network - possibly also in the future, in the sense of a prediction - more power is offered than is consumed, so that the consumed power is to be increased for stabilization.
  • the network stability parameter indicates that less power may be used to stabilize the electrical network; that is, in the electrical network - possibly also in the future, in the sense of a prediction - less service offered than accepted, so that the accepted service should be reduced for stabilization.

  • it can also be used as a - at least virtual - control power source in that it quasi releases power requirements in times of reduced power in the electrical network, that is to say it decreases or draws less electrical power.
  • a higher prioritization value is understood here to mean a prioritization value which - in comparison to a prioritization value of another calculation task - indicates a higher urgency of a calculation task.
  • a lower prioritization value is understood to mean a prioritization value which - compared to a prioritization value of another calculation task - indicates a lower urgency of a calculation task.
