Abstract

Steuereinheit zur Leistungsregelung von Netzwechselrichtern in Verbindung mit Batteriespeichern und Lastmanagement dadurch gekennzeichnet, dass die Steuereinheit Statussignale eines Funkrundsteuerempfängers oder einer anderen Vorgabeeinheit liest und auswertet.Control unit for power control of line inverters in conjunction with battery storage and load management characterized in that the control unit reads and evaluates status signals of a radio ripple control receiver or other default unit.

Description

Konzeptconcept

Energiemanagementsysteme können so konzipiert werden, dass die Einspeiseleistung in das Stromnetz limitiert werden kann, zum Beispiel abhängig von der Nominalleistung einer Fotovoltaikanlage.Energy management systems can be designed so that the feed-in power can be limited in the power grid, for example, depending on the nominal power of a photovoltaic system.

Zum Beispiel soll die Netzeinspeiseleistung eines Energiemanagementsystems auf 60% maximal begrenzt werden. Die Vorgabe des Versorgungsnetzbetreibers zur weiteren Reduzierung der Einspeiseleistung zum Beispiel auf 30% oder auf 0% wird berücksichtigt.For example, the grid feed-in capacity of an energy management system should be limited to a maximum of 60%. The requirement of the grid operator to further reduce the feed-in power to, for example, 30% or 0% is taken into account.

Funktionsbeschreibungfunction Description

Eine Steuereinheit (7) erfasst die Erzeugungsleistung einer Erzeugungsanlage (3), zum Beispiel einer Fotovoltaikanlage. Weiterhin wird der Verbrauch in der Hausinstallation (4), der Verbrauch der steuerbaren Lasten (6) und die Lade-/Entladeenergie aus dem Batteriespeicher (5) erfasst.A control unit ( 7 ) records the production output of a generation plant ( 3 ), for example a photovoltaic system. Furthermore, the consumption in the house installation ( 4 ), the consumption of controllable loads ( 6 ) and the charge / discharge energy from the battery storage ( 5 ) detected.

Aus den erfassten Energiemengen errechnet die Steuereinheit (7) die Energiemenge, die in das Stromnetz (1) abfließt, oder von dort bezogen wird. Eine direkte Messung durch Sensoren oder Zähler ist möglich.From the recorded amounts of energy, the control unit calculates ( 7 ) the amount of energy entering the grid ( 1 ) drains, or is sourced from there. A direct measurement by sensors or counters is possible.

Beim Erreichen bestimmter Leistungswerte kann die Steuereinheit (7) über eine Umsetzungseinheit (9) die Leistung der Netzwechselrichter verändern und steuerbare Lasten (6) an- oder abschalten.When certain power levels are reached, the control unit ( 7 ) via a conversion unit ( 9 ) change the power of the power inverters and controllable loads ( 6 ) on or off.

Die Umsetzungseinheit (9) kann Signale eines Funkrundsteuerempfängers (8) lesen, auswerten und direkt mit den Netzwechselrichtern kommunizieren. Die Steuereinheit (7) wird zwischen dem Funkrundsteuerempfänger (8) und der Umsetzungseinheit (9) geschaltet, so dass die Steuereinheit (7) den vorgegebenen Leistungswert vom Funkrundsteuerempfänger erfasst, die Leistungsbilanz erstellt und dann den Netzwechselrichtern über die Umsetzungseinheit (9) durch Variation der Statussignale Leistungswerte vorgibt.The implementation unit ( 9 ) can receive signals from a radio ripple control receiver ( 8th ) read, evaluate and communicate directly with the network inverters. The control unit ( 7 ) is between the radio ripple control receiver ( 8th ) and the implementation unit ( 9 ), so that the control unit ( 7 ) detects the predetermined power value from the radio ripple control receiver, generates the power balance and then sends it to the network inverters via the conversion unit ( 9 ) specifies power values by varying the status signals.
