Description
Die Erfindung betrifft eine Anordnung zur erweiterten Bereitstellung von Regelleistung zur Gewährleistung der Systemsicherheit und zur Nutzung im EEG-Ausgleichsenergieverfahren in Elektroenergieverbundsystemen, insbesondere mit Energieeinspeisung aus Windkraftanlagen. Durch die Erfindung kann diese negative Regelleistung einem Übertragungsnetzbetreiber außerdem im Rahmen des EEG-Ausgleichsenergieverfahrens zur Verfügung gestellt werden.The The invention relates to an arrangement for extended provision from control power to warranty system safety and use in the EEG balancing energy process in electrical energy systems, in particular with energy supply from wind turbines. By the invention, this negative control power a transmission system operator Furthermore provided in the framework of the EEG balancing procedure become.
Regelleistung wird bekanntlich zur Gewährleistung der Systemsicherheit in Elektroenergieverbundsystemen benötigt, um den in einer bestimmten Regelzone anfallenden Energiebedarf mit der dafür erforderlichen Energiebereitstellung im Gleichgewicht zu halten.control power is known to guarantee System security in electrical power systems needed to the energy consumption in a certain control area the required Keep energy supply in balance.
EEG-Ausgleichsenergie wird vom Übertragungsnetzbetreiber benötigt, um Differenzen zwischen der Prognose der aufgenommenen regenerativen Einspeisung von Windkraft und der wetterbedingten tatsächlichen Einspeisung auszugleichen sowie die Strukturierung in eine Bandlieferung gegenüber den aufnahmeverpflichteten EVU's zu realisieren.RESA Balancing Energy is from the transmission system operator needed to differences between the forecast of the recorded regenerative Injection of wind power and the weather-related actual Balancing feed-in as well as the structuring into a ribbon delivery across from the registered RUs to realize.
Die zunehmende Nutzung alternativer Energiequellen, wie die der stark fluktuierenden Windkraft, erfordert zur Vermeidung von Netzzusammenbrüchen eine gegenüber konventionell thermischer Energieerzeugung erweiterte Bereitstellung von Regelleistung und EEG-Ausgleichsenergie.The increasing use of alternative energy sources, such as those of the strong fluctuating wind power, requires to avoid network collapse one across from conventional thermal power generation advanced deployment of control power and EEG balancing energy.
Während die ausfallende Einspeisung von Strom aus Windkraft in Schwachwindphasen meist von thermischen Energieerzeugern ausgleichbar ist, wird in Starkwindphasen die Bereitstellung von negativer Regelleistung bei nicht adäquater Abnahme durch Verbraucher in bisher nicht gekanntem Umfang erforderlich.While the Failing supply of electricity from wind power in weak wind phases is usually compensated by thermal energy generators, is in Strong wind phases contribute to the provision of negative control power not adequate Consumption by consumers to an unprecedented extent required.
Die bekannte Möglichkeit des Einsatzes von Pumpspeicherkraftwerken stößt hinsichtlich der verfügbaren Kapazitäten, der begrenzten topografischen Möglichkeiten sowie der Genehmigungsfähigkeit der Erweiterung der vorhandenen Kapazitäten an wenig verrückbare Grenzen.The known possibility The use of pumped storage power plants comes up against the available capacities, the limited topographical possibilities as well as the authorization capability the extension of existing capacities to unobtainable borders.
Zum Ausgleich von Energieerzeugung aus fluktuierender Windkraft wurden bereits Druckluftspeicher-Gasturbinen-Kraftwerke vorgeschlagen, die gegenüber thermischen Kraftwerken auch negative Regelleistung bereitstellen können.To the Compensation of power generation from fluctuating wind power were already proposed compressed air storage gas turbine power plants, the opposite thermal power plants also provide negative control power can.
Die verfügbare Kapazität derartiger Druckluftspeicher-Gasturbinen-Kraftwerke kann jedoch auch in nächster Zeit nicht der sich wesentlich schneller entwickelnden Kapazität der Windkraftanlagen gerecht werden.The available capacity However, such compressed air storage gas turbine power plants can also In the next Time not the much faster developing capacity of wind turbines satisfy.
Es ist daher Aufgabe der Erfindung, den insbesondere bei Nutzung von Windkraft zur Energieerzeugung erforderlichen hohen Bedarf an Regelleistung zur Netzstabilisierung, Frequenzhaltung und EEG-Profilstrukturierung für das sensibel reagierende Elektroenergieverbundsystem durch elektrische Verbindung mit einem weniger sensibel reagierenden System, insbesondere einem Heißwasser- und Fernwärmesystem, bereitzustellen.It is therefore an object of the invention, in particular when using Wind power required for power generation high demand for control power for grid stabilization, frequency maintenance and EEG profile structuring for the sensitively reacting electric power system by electrical connection with a less responsive system, especially one hot water and district heating system, provide.
Erfindungsgemäß wird die Aufgabe gelöst, indem sowohl rasch verfügbare als auch ebenso rasch abschaltbare negative Regelleistung durch sinnvolle Verwertung von erzeugten Stromüberschuss in Starkwindphasen durch Nutzung von elektrischen Dampf- bzw. Heißwassererzeugern in Heißwasser -und Fernwärmesystemen innerhalb einer Regelzone als dieser zugeordneten Stromverbraucher bereitstellbar ist.According to the invention Task solved by both readily available as well as quickly disconnectable negative balancing power by meaningful Utilization of electricity surplus generated in strong wind phases through the use of electric steam or hot water generators in hot water and district heating systems within a control zone as this associated power consumers is available.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden.The Invention will be explained in more detail below using an exemplary embodiment.
Rasch verfügbare Regelleistung wird beim zunehmenden Ausbau von Kapazitäten der Elektroenergieerzeugung mit erneuerbaren Energien, wie insbesondere der Windkraftnutzung, benötigt.quickly available Regular power will be used as capacity expands Electric power generation with renewable energies, in particular the wind power use, needed.
Bei der Einspeisung von aus Windkraft erzeugter Energie muss die Netzregelung sowie das EEG-Ausgleichsverfahren auch solche spezifischen Extremfälle beherrschen, wie einmal den Verbrauch von erzeugter Überschussenergie in Starkwindphasen und zum anderem die abrupte Abschaltung der Energieerzeugung aus Windkraft durch Sicherheitsabschaltung der Anlagen beim Erreichen deren Leistungsgrenzen.at The feed-in of energy generated from wind power must be regulated by the grid as well as the EEG-equalization procedure also dominate such specific extreme cases, like once the consumption of generated excess energy in strong wind phases and on the other hand, the sudden shutdown of power generation Wind power through safety shutdown of the systems on reaching their performance limits.
Die Nutzung von in Heißwassersystemen oder Fernwärmesystemen angeordneter elektrischer Dampf- bzw. Heißwassererzeuger als innerhalb einer Regelzone definierter Stromverbraucher, gestattet es, in Phasen der überschießenden Erzeugung von Energie aus Windkraft diese im Rahmen der jeweiligen Regelzone und im Umfang der erforderlichen Netzregelung sinnvoll zur elektrischen Erzeugung von Wärme einzusetzen Beim Ausfall des von Windkraftanlagen innerhalb einer Starkwindphase gerade erzeugten Stromüberschusses durch Sicherheitsabschaltung dieser Anlagen, können die im Dampf- bzw. Heißwassersystem befindlichen elektrischen Dampf- bzw. Heißwassererzeuger im Umfang der erforderlichen Netzregelung auch rasch elektrisch abgeschaltet werden.The Use in hot water systems or District heating systems arranged electric steam or hot water generator as within A control zone defined power consumers, it allows, in phases the over generation of energy from wind power this within the respective control zone and in the scope of the required grid regulation useful for electrical Generation of heat In case of failure of wind turbines within one Strong wind phase just generated excess current due to safety shutdown of these facilities, can in the steam or Hot water system located electrical steam or hot water generator in the scope of required grid control can also be quickly switched off electrically.
Die Verwendung von in Dampf- bzw. Heißwassersystem befindlichen definierten elektrischen Dampf- bzw. Heißwassererzeugern ist darüber hinaus auch im Rahmen einer Regelzone im Umfang des jeweiligen Energieangebotes zur gewöhnlichen Bereitstellung von erneuerbarer Energie zwecks Erzeugung von Dampf- bzw. Heißwasser geeignet.The use of defined in steam or hot water system defined electric steam or hot water generators is over from within a control area within the scope of the respective energy supply for the usual provision of renewable energy for the purpose of generating steam or hot water suitable.
