Abstract
(DE)
Die Erfindung betrifft eine Anordnung umfassend einen regenerativen Energieerzeuger (1) und einen Speicher (2) für elektrische Energie zur Abgabe an ein Netz (9), wobei der regenerative Energieerzeuger (1) einen Energiewandler (13) zur Wandelung erneuerbarer Energiequellen in elektrische Energie sowie eine Leistungssteuereinheit (10) aufweist, welche einen Eingang für eine Soll-Leistungsabgabe aufweist und die Leistungserzeugung durch den regenerativen Energiewandler (13) kontrolliert, und ferner eine Ladesteuerung (20) für den Speicher (2) vorgesehen ist, welche eine bereitzustellende Mindest-Regelenergie einstellt und ein Signal für einen Soll-Ladestand (SoC) des Speichers (2) ausgibt. Um eine bessere Nutzung des Speichers zu erreichen, ist auf die Ladesteuerung (10) eine Korrektureinheit (4) aufgeschaltet, die das Signal für den Soll-Ladestand (SoC) laufend modifiziert, und eine Folgesteuereinheit (5) vorgesehen ist, welche von der Korrektureinheit (4) angesteuert ist und auf die Leistungssteuereinheit (10) des regenerativen Energieerzeugers einwirkt abhängig von einem Ausgangswert der Korrektureinheit (4).
(EN)
The invention relates to an arrangement comprising a regenerative energy generator (1) and a store (2) for electrical energy to be output to a grid (9), the regenerative energy generator (1) comprising an energy converter (13) for converting renewable energy sources into electrical energy and a power control unit (10) which has an input for a target power output and controls the power generation by the regenerative energy converter (13), with a charge controller (20) for the store (2) also being provided, which sets a minimum operating reserve to be provided and outputs a signal for a target state of charge (SoC) of the store (2). In order to achieve improved utilisation of the store, a correction unit (4) is connected to the charge controller (10) and continuously modifies the signal for the target state of charge (SoC). A sequence control unit (5) is also provided, which is actuated by the correction unit (4) and influences the power control unit (10) of the regenerative energy generator according to an output value of the correction unit (4).
(FR)
La présente invention concerne un agencement comportant un générateur d'énergie renouvelable (1) et un accumulateur (2) pour de l'énergie électrique à fournir à un réseau (9). Le générateur d'énergie renouvelable (1) comprend un convertisseur d'énergie (13) pour la conversion de sources d'énergie renouvelable en énergie électrique ainsi qu'une unité de commande de puissance (10) qui comprend une entrée pour une fourniture de puissance de consigne et contrôle la génération de puissance par le convertisseur d'énergie renouvelable (13), et en outre une commande de charge (20) pour l'accumulateur (2) qui règle une énergie de régulation minimale à fournir et délivre un signal pour un état de charge de consigne (SoC) de l'accumulateur (2). Pour obtenir une meilleure utilisation de l'accumulateur, la commande de charge (10) comprend une unité de correction (4) qui modifie en permanence le signal pour l'état de charge de consigne (SoC) et commande une unité de commande de suivi (5) qui agit sur l'unité de commande de puissance (10) du générateur d'énergie renouvelable en fonction d'une valeur de sortie de l'unité de correction (4).
