Abstract

Una estación de energía fotovoltaica (PV) incluye al menos una unidad de producción de energía de CA. La unidad de producción de energía de CA incluye un depósito de energía que se suministra con energía de CD desde un generador de energía de CD, tal como paneles PV. El depósito de energía se utiliza como regulador para almacenar energía y mejorar la eficiencia de la estación de energía PV. A sea que se use o no un depósito de energía, se pueden usar dispositivos desacopladores para evitar la aniquilación de energía que puede disminuir la cantidad de energía entregada por la estación de energía a la red. En la integración del sistema para una estación de energía PV, se encuentra que la clasificación declarada del convertidor de CD/CA en la convención de la red eléctrica no debe tomarse como la capacidad de conversión de energía.A photovoltaic (PV) power station includes at least one AC power production unit. The AC power production unit includes a power reservoir that is supplied with DC power from a DC power generator, such as PV panels. The energy reservoir is used as a regulator to store energy and improve the efficiency of the PV power station. Whether or not a power store is used, decoupling devices can be used to prevent power annihilation that can decrease the amount of power delivered by the power station to the grid. In system integration for a PV power station, it is found that the stated rating of the DC/AC converter in the power grid convention should not be taken as the power conversion capacity.
