Abstract

Un método de control de una pluralidad de convertidores de CC/CA en configuración en cascada, estando dispuesto cada uno de la pluralidad de convertidores de CC/CA (21, 22, 23) para recibir una tensión y una corriente continua de entrada de un panel fotovoltaico (FV) (11, 12, 13) respectivo, y para entregar una salida, comprendiendo el método: recibir (102) una información que representa por lo menos uno de frecuencia, fase, amplitud y armónicos de una CA requerida; recibir (104) una información que representa por lo menos una de corriente y tensión de la tensión y la corriente continua de entrada para cada uno de la pluralidad de convertidores de CC/CA; y basándose en la información recibida, controlar de forma individual (106) cada uno de la pluralidad de convertidores de CC/CA de tal modo que la salida combinada de la pluralidad de convertidores de CC/CA produce una CA que concuerda con la CA requerida, caracterizado por que una o más unidad ficticia (24) está conectada adicionalmente a la pluralidad de convertidores de CC/CA en configuración en cascada, comprendiendo dichas una o más unidades ficticias un elemento de almacenamiento de energía (34) que está adaptado para cargarse y para emitir una tensión y una corriente continua, y un convertidor de CC/CA, y usar (114) las una o más unidades ficticias para producir una salida de tal modo que la salida combinada desde la pluralidad de convertidores de CC/CA produce una CA que concuerda con la CA requerida.
