Abstract

Es wird ein Verfahren zur Spannungsstabilisierung in einem Niederspannungsnetz beschrieben. Bei diesem Verfahren wird zunächst ein Netzknoten i bestimmt, an dem die Spannung außerhalb eines gewünschten Spannungsbereiches liegt und es wird eine Spannungsänderung ∆Ui,bestimmt, die erforderlich ist, um diesen Netzknoten wieder in den gewünschten Spannungsbereich zurückzuführen. Anschließend werden Änderungsvorgaben für Blindleistung und/oder Wirkleistung einer Vielzahl von Betriebsmitteln gemäß einer vordefinierten Betriebsstrategie in Abhängigkeit der erforderlichen Spannungsänderung ∆Ui, bestimmt und Änderungsvorgaben werden durch die Betriebsmittel umgesetzt. Eine zentrale Betriebsführungseinheit steuert die Spannungshaltung in dem Niederspannungsnetz.
