摘要: An example system includes a power source that outputs direct current (DC) power drawn from one or more power cells. The system also includes a controller coupled to the power source. The controller is configured to obtain first control logic executable by the controller to operate a genset that outputs alternating current (AC) power drawn from an alternator of the genset. The controller is also configured to generate, based on the first control logic, second control logic executable by the controller to operate the power source. The controller is also configured to execute the second control logic to operate the power source.

摘要: In einem Verfahren zum Betrieb eines Energieversorgungssystems (10) tauschen einer ersten und einer zweiten DC-Einheit (22, 26, 28) über einen ersten beziehungsweise zweiten Leistungswandler (12, 14, 16, 18) Leistung mit einem AC-Bus (20) aus. Unter Übertragung über einen Transformator (32) wird diese Leistung dann zusammengeführt und über einen dritten Leistungswandler (34) in eine DC-Netzleistung eines DC-Netzes (30) und/oder umgekehrt gewandelt, wobei zumindest die erste DC-Einheit (22) als Energieerzeugungseinheit, insbesondere als PV-Anlage mit zumindest einem PV-Generator (24) ausgebildet ist, wobei eine Frequenz und eine Amplitude der AC-Spannung und/oder des AC-Stromes auf dem AC-Bus (20) eingestellt werden, und wobei der dritte Leistungswandler (34) die Frequenz auf dem AC-Bus (20) in Abhängigkeit von der DC-Netzleistung einstellt und zur Einstellung der AC-Spannung und/oder des AC- Stroms die DC-Netzleistung in Abhängigkeit von der AC-Busleistung einstellt. Weiterhin ist eine Vorrichtung zum Austausch elektrischer Leistung in einem Energieversorgungssystem (10), sowie ein entsprechendes Energieversorgungssystem (10) beschrieben.
