Definitions

  • the invention relates to a method for operating a wind turbine or several wind turbines combined in a wind farm, as well as a control device designed for carrying out the method and a corresponding computer program product.
  • Wind turbines are known from the prior art. They usually include a rotor with several - usually three - rotor blades.
  • the rotor is rotatably mounted on a nacelle, the nacelle in turn being rotatably mounted on a tower. If necessary, the rotor drives a generator via a rotor shaft and a gear.
  • a wind-induced rotational movement of the rotor can be converted into electrical energy, which can then be fed via converters and / or transformers - depending on the type of generator also at least partially directly - in an electrical network.
  • the networks into which a wind energy plant or a group of wind turbines directly feeds the energy generated constitute a potential bottleneck for energy supply, which results from the protection of the components used there, such as transformers, etc.
  • Whether and to what extent wind turbines are actually available for system services depends inter alia on the available, free transmission capacity of the network in which a wind turbine feeds its power.
  • this free transmission capacity constantly changes with the power actually fed into the network, whereby the free transmission capacity, in particular in high-wind phases with correspondingly high power supply, can certainly also drop to zero. Since, however, no possibility is known from the prior art to provide variable power feed as a system service even with fluctuating free transmission capacity in a local area network In the prior art, wind turbines are not regularly used to provide ancillary services.
  • the object of the present invention is to provide a method, a control device and a computer program product with which wind energy plants can be used to provide ancillary services.
  • the invention relates to a method for operating a wind energy plant or several wind energy plants connected to a wind farm with a control device for controlling the power supply of the wind turbine (s), the control device for receiving control signals of at least two higher-level control systems with different wind turbines. rather priority is formed, with the steps:
  • control device is reserved for the higher-level control from which the control signal originates:
  • the invention relates to a control device for controlling the power supply of a wind turbine or several wind turbines combined in a wind farm, wherein the control device is designed to receive control signals of at least two higher-level control systems with different priority via a remote data transmission network, wherein the control device for Implementation of the method according to the invention is formed.
  • the invention also relates to a computer program product comprising program parts which, when loaded in a computer, preferably a control device of a wind turbine or of a wind farm, are designed for carrying out the method according to the invention.
  • the power supply and other functions of a wind energy plant or of wind farms can be controlled by external control signals sent to the respective control device of the wind energy plant or the wind farm, this control signal regularly coming from a single superordinate control.
  • the invention has recognized that the implementation of control signals from various superordinate control systems is advantageous for providing system services by wind turbines. In order to achieve sufficient security in the availability of wind turbines for system services and at the same time to protect the network to which the wind energy plant (s) is or are connected from overload, two measures are provided according to the invention.
  • the one higher-level controller is assigned to the operator of the network into which the wind energy plant or the wind farm feeds directly, while the other higher-level control is assigned to a system service provider who calls system services as required to ensure network stability in transmission networks.
  • the network operator-associated controller enjoys a higher priority than the controller assigned to the system service provider.
  • the higher-order controllers are assigned differently and / or more than two higher-level controllers are provided, whereby at least one of the control systems has a higher priority than another of the higher-level controllers.
  • other higher-level controls for example a direct distributor of electrical energy, may also be provided.
  • the control device can be reserved for predetermined or resulting from the operation control or received control signals flexible time points for a particular higher-level control, whose control signals are to be implemented primarily.
  • a timetable stored in the control device it can be determined from which higher-level control control signals are primarily converted.
  • the timetable can be created by the control device itself, one of the higher-level controls or another separate unit and transmitted to the control device and / or possibly the higher-level controls. Based on forecasts, the timetable can in principle specify at which times a wind turbine or a wind farm is available for a specific higher-level control, for example for system services, if necessary.
  • Forecasts can be, for example, weather forecasts, in particular wind forecasts, but also consumption forecasts based on empirical values, on the basis of which u. a. the load of the network into which the wind turbine or wind farm feeds can be predicted. For times when a high network utilization is to be expected, it can then be specified in the timetable, for example, that in principle only control signals of the superordinate control assigned to the network operator are implemented, which regularly serve to protect the network.
  • the other higher-level control systems can use the timetable to recognize that at some point in time a particular wind turbine or wind farm is not available for them, for example for the provision of ancillary services. In this case, for example, a system service provider must retrieve a possibly required system service from another generator unit.
  • the control device of the wind energy plant or of the wind farm is in principle designed to actually implement only those control signals in the control of the wind energy plant or the wind farm, which come from that parent control, for which the control device - eg., According to the timetable - is reserved.
  • control device may be configured to receive the received signal Still implement control signal.
  • a wind energy installation or a wind farm can also be used, for example, to provide ancillary services if it is not explicitly reserved for it.
  • control signals of other higher-level control systems are not implemented in principle.
  • control device for a given period and / or until the next proper reservation - for example according to the timetable - for that is superordinate control, from which the control signal comes.
  • the reservation for precisely this higher-level control can be limited in time, for example to a predetermined period of time. It is advantageous, however, if such a reservation is valid at most up to the time at which, for example, according to the timetable, there is a reservation for a specific higher-level control. This can ensure that a possibly specified timetable is basically adhered to.
  • control signals of a higher-level control are only implemented if the control device is reserved for this control or there is no reservation can be deviated according to the invention if a control signal is received from a higher-level control whose priority is higher than the priority of the parent controller for which the controller is currently reserved. If a control signal originates from a higher-level controller with a correspondingly higher priority, the control signal can be converted despite a different reservation. In this way, it can be ensured, for example, that a network operator can reduce or completely switch off the power supply of a wind energy plant or wind farm, even if the wind energy plant or the wind farm is actually a system service provider for the provision of systems. services should be available. In order to prevent control signals from higher-level higher-level controls from being directly implemented, it may be provided that the controller receives an acknowledgment from the higher-priority control unit with the higher priority that its control signal actually has to be implemented.
  • control signal of a higher-level control system is implemented according to the schedule, for example according to the timetable, it is preferred for the higher-level control to use the control device for a predetermined time period and / or until the next reservation has been made correctly, for example according to the timetable reserved for the higher priority.
  • control for which the control device is reserved is notified that the control device is no longer available despite a reservation.
  • the higher-priority controller can be informed that the control device currently not available. In this way, it can be ensured, for example, that the higher-level controllers, in addition to the information from a timetable, for which ordered control a controller is reserved at a given time, be informed immediately about the reservation state and in particular any deviations from just this roadmap. This information can be taken directly into account by the higher-level controllers.
  • the timetable is in the form of a block chain, which is preferably stored in the control device and at least one, preferably all superordinate control devices.
  • a blockchain By using a blockchain, it can be ensured that the schedule is identical and tamper-proof for each unit where the blockchain is stored. At the same time, the schedule or block chain can easily be updated when making reservations for a new forecast period.
  • the timetable includes, for example, the period of time for a particular reservation as well as a clear identification of the superior control to which the reservation applies. It may be sufficient if only the start time of a reservation is stored in the timetable, wherein the period of the reservation results from the start time of the subsequent reservation. In the timetable, such times in which the wind power plant or the wind farm, for example, is shut down for maintenance reasons and thus can not feed in power, can be deposited.
  • the blockchain may contain further information in the sense of smart contracts, by means of which contractual agreements are mapped in the case where a control device, contrary to the original reservation, does not represent the higher-level control for which she is actually reserved, is available.
  • a smart contract for example, special allowances or contractual penalties can be mapped, which can then be billed automatically.
  • a smart contract can, for example, include a chain of commands, according to which the relevant measurement data and control commands of the time interval are signed together with the contract data with a secret key and / or sent to an address stored in the smart contract.
