An approach to day ahead forecasting of solar irradiance with an application to energy gain in solar thermal collectors
2014
Masteroppgave i fornybar energi ENE 500 Universitetet i Agder 2014 Today, for the management of energy supply systems forecast information on load and theproduction of meteorology dependent (wind, solar, hydro) generation is ever rising. Solarirradiance forecasting is given a unique priority as it spans over major applications such asmanagement of grids with a high share of photovoltaic generation and thermal power supplysystems relying on solar heat generation. This thesis will address the day ahead prediction of thelocal irradiances intended to be applied for the management of solar assistant systems for heat andhot water supply. The forecast method presented here is based on the statisti…
Optimizing subsurface dripline installation depth with Hydrus 2D/3D to improve irrigation water use efficiency in the central Tunisia
2015
The main objective of the work is to optimize drip installation depth for Eggplant crop irrigated with surface or subsurface drip irrigation systems to improve irrigation Water Use Effeciency (WUE), by means of field measurements and simulations carried out with Hydrus-2D model. Initially, a comparison between simulated Soil Water Contents (SWC) and the corresponding measured in two plots, in which laterals with coextruded emitters are laid on the soil surface (T0) and at 20 cm depth (T20), respectively. In order to choose the best position of the lateral, the results of different simulation run, carried out by choosing a deeper installation (T45) depth. Simulated SWC’s resulted fairly clos…
