Resumen
Durante unos días a mediados de marzo de 2022, toda la España continental estuvo expuesta a una importante tormenta de polvo. Este evento, comúnmente conocido como calima, debido al transporte de polvo sahariano, tiene un impacto significativo en la producción de energía fotovoltaica, ya que reduce la cantidad de radiación. Este estudio investiga analíticamente el efecto de ese episodio, cuantificando el impacto que tuvo en los componentes de radiación individuales para cuatro ciudades de España. Para eliminar el efecto de las nubes, se utilizan datos de cielo despejado descargados de Copernicus. La irradiación directa resulta ser el componente más afectado, mientras que en la mayoría de las localidades se registró un aumento de la radiación difusa, debido a la dispersión de la luz provocada por el polvo en suspensión.
Over a few days in mid-March 2022, the whole continental Spain was exposed to an important dust storm. This event, commonly known as calima, due to the transport of Saharan dust, has a significant impact on the photovoltaic power production, because it reduces the amount of radiation. This study analytically investigates the effect of that episode, quantifying the impact that it had on the individual radiation components for four cities across Spain. In order to remove the effect of clouds, clear-sky data downloaded from Copernicus are used. Direct irradiance is found to be the most affected component, while an increase in diffuse radiation, due to the scattering of light caused by the suspended dust, was registered in most of the locations.
