Abstract
Description
Die Erfindung betrifft ein Verfahren zum Management der Last eines elektrischen Netzes, bei dem dann, wenn ein Überangebot an elektrischer Energie vorhanden ist, den Strombeziehern ein Signal übermittelt wird, durch das einzelne Verbrauchsgeräte des Strombeziehers automatisch frei- bzw. ein bzw. ausgeschaltet werden.The invention relates to a method for managing the load of an electrical network, in which, when an oversupply of electrical energy is present, the Strombeziehern a signal is transmitted by the individual consumption devices of the Strombeziehers automatically free or on or off.
Das sog. Lastmanagement ist ein bewehrtes Verfahren zum Vergleichmäßigen der Last eines elektrischen Netzes: Bei einem Überangebot an elektrischer Energie werden bestimmte Verbraucher freigegebn, bei einer Übernachfrage an elektrischer Energie werden demgegenüber einzelne Gebrauchsgeräte des Strombeziehers automatisch ausgeschaltet.The so-called load management is a reinforced procedure for equalizing the load of an electrical network: In the event of a surplus of electrical energy, certain consumers are released, and in the event of an over-demand for electrical energy, individual utility devices of the electricity user are automatically switched off.
Das Potential der Steuerung der Verbrauchsgeräte ist aber im Hinblick auf die Zunahme von stochastisch einspeisenden Energien, insbesondere der Windenergie, unzureichend. Da die konventionellen Kraftwerke nicht entsprechend der Zunahme der Einspeisung aus regenerativen Quellen zurückgefahren werden können, müssen im Hinblick auf die unzureichende Kapazität der Netze einzelne Anlagen, beispielsweise Windenergieanlagen, ausgeschaltet werden. Dies ist natürlich unerwünscht.However, the potential of the control of the consumer devices is insufficient in view of the increase of stochastically feeding energies, in particular wind energy. Since conventional power plants can not be scaled back in line with the increase in feed-in from regenerative sources, individual systems, such as wind turbines, must be eliminated in view of the insufficient capacity of the grids. This is of course undesirable.
Der Erfindung liegt damit die Aufgabe zugrunde, ein Verfahren zu schaffen, bei dem auch zu Zeiten eines Überangebots an elektrischer Energie durch Zuschalten weiterer Verbrauchsgeräte die Energie aus den Windenergieanlagen in das Netz eingespeist werden und Ortsnah verbraucht werden können.The invention is therefore based on the object to provide a method in which even at times of oversupply of electrical energy by connecting additional consumer devices, the energy from the wind turbines are fed into the network and can be consumed locally.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass eines der Verbrauchsgeräte ein auf den Heizwasserkreislauf der Heizungsanlage des Strombeziehers wirkendes elektrisches Heizelement ist. Das Heizelement wird bei Bedarf zur Einschaltung freigegeben oder automatisch eingeschaltet und bei Ausbleiben der Voraussetzungen von der Freigabe ausgenommen bzw. ausgeschaltet.According to the invention, this object is achieved in that one of the consumption devices is an acting on the Heizwasserkreislauf the heating system of the Strombeziehers electric heating element. If necessary, the heating element is enabled for switching on or automatically switched on and, if the requirements are not met, excluded or deactivated from the release.
Bei einer anderen Ausführungsform ist das Verbrauchsgerät ein auf den Heizwasserkreislauf der Heizungsanlage des Strombeziehers wirkendes elektrisches Kühlelement. Dieses Ausführungsbeispiel wird dann Verwendung finden, wenn die Heizungsanlage des Strombeziehers als Kühlanlage verwendet werden soll.In another embodiment, the consumption device is an acting on the Heizwasserkreislauf the heating system of Strombeziehers electric cooling element. This embodiment will be used when the heating system of the Strombeziehers is to be used as a cooling system.
Das elektrische Element ist vorzugsweise im Pufferspeicher der Heizungsanlage angeordnet, es kommt jedoch auch eine Ausbildung in Betracht, bei der das elektrische Element eine um ein Rohrstück des Heizwasserkreislaufs gelegte, mit einem an dem Rohrstück anliegenden Widerstandselement versehene Heiz- bzw. Kühlmanschette ist.The electrical element is preferably arranged in the buffer memory of the heating system, but it is also a formation into consideration, in which the electrical element is a laid around a pipe section of Heizwasserkreislaufs, provided with a voltage applied to the pipe section resistance element heating or cooling sleeve.
Bei dem Signal handelt es sich vorzugsweise um ein Preissignal, das das elektrische Heizelement bei Unter- bzw. Überschreiten eines vom Strombezieher vorgewählten Preises anstatt des Aktivieren bzw. Deaktivieren des Brenners der Heizungsanlage ein- bzw. ausgeschaltet wird bzw. zur Einschaltung freigegeben wird oder von der Freigabe ausgenommen wird. Entsprechend wird das Kühlelement bei Unter- bzw. Überschreiten eines vom Strombeziehers vorgewählten Preises ein- bzw. ausgeschaltet oder freigeschaltet bzw. von der Freischaltung ausgenommen.The signal is preferably a price signal, which is switched on or off for switching on or off for switching on the electrical heating element at undershooting or exceeding a preselected by the current consumer price instead of activating or deactivating the burner of the heating system or the release is excluded. Accordingly, the cooling element is switched on or off or released from the activation in under or exceeding a preselected by the Strombeziehers price or unlocked.
Dabei versteht sich, dass das elektrische Heizelement nur dann aktiviert wird, wenn in der Anlage Wärme bzw. Kältebedarf besteht.It is understood that the electric heating element is activated only when there is heat or cooling demand in the system.
Bevorzugt wird das Preissignal von einer Zentrale aus an eine elektrische Spannung auf Niederspannung herabsetzende Trafostation ermittelt, in der das Preissignal umgesetzt und dem von der jeweiligen Trafostation versorgten Niederspannungsnetz aufgeprägt wird.The price signal is preferably determined from a control center to a transformer substation which reduces electrical voltage to low voltage, in which the price signal is converted and impressed on the low-voltage network supplied by the respective transformer station.
Die Übermittlung der Preisinformation an die Trafostation erfolgt vorzugsweise über das diese versorgende Stromnetz, über eine Telefonleitung, ein Glasfaserkabel oder drahtlos, wobei auch hier ein Aufprägen über eine Rundsteueranlage oder aber eine Übermittlung über das Internet, die Telefonleitung oder ein Glasfaserkabel oder drahtlos erfolgt.The transmission of the price information to the transformer station is preferably carried out over the power supply network, via a telephone line, a fiber optic cable or wirelessly, whereby also an imposition via a ripple control system or a transmission via the Internet, the telephone line or a fiber optic cable or wireless.
Darüber wird dem Strombezieher neben der Übermittlung der Information zur Vorlage von Überschussstrom bevorzugt auch der jeweils aktuelle Abgabepreis für den Strom übermittelt.In addition to the Strombezieher in addition to the transmission of information for the presentation of surplus power preferably also the current selling price for the power is transmitted.
