One of the most effective and cheapest strategies to integrate the fast-increasing number of solar-based generators is by forecasting their power output to schedule power dispatch, energy storages, manage backup generators, and compensate for any fluctuations of solar power. In particular, forecasting the insolation is invaluable to predict the power generated by photovoltaic arrays. An essential...
There are many phenomena that cause losses to signal during transmission through the earth's atmosphere. One of them is scintillation. Scintillation arises from atmospheric refractive index discontinuities and resulting in random fades and fluctuation of the received signals amplitude about a mean level. This is caused by small scale loopholes in the transmission path with time. It is an important...
In this paper, a mathematical model, requiring only the cloud-ground geometry, applied voltage and some atmospheric parameters, described in the first part of our contribution, has been used to predict the main macroscopic parameters of the negative lightning discharge. The predicted parameters include the spatial and temporal evolution of the entire discharge, the current and the corresponding electrical...
Fade mitigation techniques on Earth-satellite links require the estimation of channel propagation conditions. This is generally done by using downlink measurements at a lower frequency to derive the channel uplink propagation conditions at higher frequencies. Moreover, when atmospheric conditions are changing, the ground stations have to change their own configuration (increase or decrease transmit...
