Abstract

This paper presents a characterization of the wind energy in Portugal in what regards: the installed power capacity, the capacity under construction, and the geographical location of wind turbines. The Portuguese lightning location system (LLS) is described, and new experimental and analytical results are presented. Analysis about geographical and time distribution of cloud-to-ground (CG) strikes and accumulative probability of peak current are carried out. Also, new ground flash density (GFD) maps are presented. Hence, the paper improves the knowledge about the lightning activity in Portugal, allowing the enhancement of risk analysis studies.
