Abstract

Un système (1) photovoltaïque comprenant une pluralité de chaînes (i) de panneaux photovoltaïques (3i,j), chacune incluant une sortie d'un optimiseur (5i) et une pluralité de panneaux photovoltaïques (3i,j) montés en série les uns avec les autres. La sortie de chaque optimiseur (5i) étant équipée d'un convertisseur bidirectionnel en puissance. Les optimiseurs (5i) sont alimentés en entrée par une tension d'entrée d'un bus (9) commun aux chaînes (i). Les chaînes (i) sont montées en parallèle les unes des autres et en parallèle avec l'entrée d'un onduleur (7) commun. L'onduleur (7) est relié en sortie à un réseau externe (2). Le système (1) comprend en outre un module de commande agencé de manière à commander la tension en entrée (Vinv_DC) de l'onduleur (7) au cours du temps (t) de manière à annuler, aux pertes près et en moyenne sur une période (T), l'énergie échangée entre les chaînes (i) et le bus (9).A photovoltaic system (1) comprising a plurality of chains (i) of photovoltaic panels (3i, j), each including an output of an optimizer (5i) and a plurality of photovoltaic panels (3i, j) connected in series with each other with the others. The output of each optimizer (5i) being equipped with a bidirectional power converter. The optimizers (5i) are supplied as input by an input voltage from a bus (9) common to the chains (i). The strings (i) are mounted in parallel with each other and in parallel with the input of a common inverter (7). The inverter (7) is connected at the output to an external network (2). The system (1) further comprises a control module arranged so as to control the input voltage (Vinv_DC) of the inverter (7) over time (t) so as to cancel, except for losses and on average over a period (T), the energy exchanged between the chains (i) and the bus (9).
