Descriptif
Considering the targeted energy supply for the North African and European region alike and its designated increase in the share of RES this study aims to answer the question : How much electrical output is achievable through Photovoltaic and Wind Energy Generation in North Africa today and in the mid- to long-term future, and at what cost ? Thereby the core objective of this diploma thesis is to analyse the North African region, in regard to its economic potential for two renewable energy sources : photovoltaic energy and wind energy. Cost-Supply Curves for the analysed region and the respective energy sources provide Levelised Cost of Electricity (LCOE) in relation to the accumulated available generation potential. Compared to previous studies, the objective of this analysis is not only to enhance the accuracy of the calculation with up-to-date, better resolution in data inputs as well as higher detail in site selection, but also to broaden the analysis : LCOE and the power generation potential for the years 2030 and 2050 will be estimated. The inclusion of grid infrastructure into the economic assessment shall refine the geographic distribution of potential electrical output. The impact of the North African environment on observed technologies and relevant developments to cope with this impact will gain importance : Concentrated PV - using the highly available direct solar irradiation in Northern Africa - and thin-film technologies will be appraised as well as mono- and polycrystalline PV technologies. The wind energy assessment will include both drive-train concepts - DFIG and EESG. Finally, it is the goal of this paper to disclose the suitability of PV and wind technologies for a decisive share in energy supply in the North African region as well as possible contributions to the electricity demand of Europe. Not included within the boundaries of this thesis is a detailed country-specific resource scheduling in the constraints of existing power plant fleets. Favourable regions for PV and wind energy installations will be defined in maps. However, advice on specific locations for possible installations are not included. Socio-economic effects on industries and workforce in the region also fall outside the scope of this analysis.
