Title
(DE) Verfahren zum Betreiben einer Anlage und Anlage
Abstract
(DE)

Verfahren zum Betreiben einer Anlage und Anlage, wobei die Anlage einen AC/DC-Wandler aufweist, dessen gleichspannungsseitiger Anschluss elektrisch parallel geschaltet ist zu einem gleichspannungsseitigen Anschluss eines Wechselrichters und einem ersten gleichspannungsseitigen Anschluss eines DC/DC-Wandlers, an dessen zweitem gleichspannungsseitigen Anschluss ein Energiespeicher, angeschlossen ist, wobei aus einem Wechselspannungsversorgungsnetz, aus welchem der wechselspannungsseitige Anschluss des AC/DC-Wandlers speisbar ist, elektrische Leistung dem gleichspannungsseitigen Anschluss des AC/DC-Wandlers zugeführt wird, wenn der Leistungsbezug des ersten Wechselrichters positiv ist, wobei die elektrische Leistung auf einen Sollwert hingeregelt wird, und dass aus dem Wechselspannungsversorgungsnetz keine elektrische Leistung dem gleichspannungsseitigen Anschluss des AC/DC-Wandlers zugeführt wird, wenn der Leistungsbezug des ersten Wechselrichters negativ ist. embedded image
