Abstract

Una central eléctrica fotovoltaica (PV) comprende por lo menos una unidad de producción de energía eléctrica de corriente alterna (CA). La unidad de producción de energía eléctrica CA incluye un almacenador de energía que se alimenta con energía eléctrica de corriente continua (CC) proveniente de un generador de energía eléctrica CC, tal como paneles fotovoltaicos (PV). El almacenador de energía se utiliza como un almacenador intermedio con el fin de almacenar energía y mejorar la eficiencia de la central eléctrica PV. Sin importar si se usa o no un almacenador de energía, pueden utilizarse dispositivos desacopladores para evitar la aniquilación de energía eléctrica que puede disminuir la cantidad de energía eléctrica inyectada por la central eléctrica a la red. En la integración del sistema para una central eléctrica PV, se constata que el régimen nominal declarado del convertidor CC/AC en la convención de la red eléctrica no debería considerarse como la capacidad de conversión de energía.A photovoltaic (PV) power plant comprises at least one alternating current (AC) electrical energy production unit. The AC electric power production unit includes an energy store that is powered by direct current (DC) electric power from a DC electric power generator, such as photovoltaic (PV) panels. The energy store is used as a buffer in order to store energy and improve the efficiency of the PV power plant. Regardless of whether or not an energy store is used, decoupling devices can be used to avoid electrical energy annihilation which can decrease the amount of electrical energy injected by the power plant into the grid. In the integration of the system for a PV power plant, it is found that the declared rating of the DC / AC converter in the power grid convention should not be considered as the energy conversion capacity.
