Abstract As part of the trend towards a clean environment, states have begun to turn to new and renewable energies. Wind and solar energies are two of the most important energies from these energies especially in cities and areas, which far from the grid, that have high wind speed, high temperatures and interference under the solar belt. According to the wind atlas of Egypt 2005, this thesis attempted to find areas that can generate good amount of wind energy, so they can be used for establishing urban communities or transfer energy to the united grid of Egypt. Beginning with dividing Egypt to areas according to the available wind speed data, a study for the windy places, that can be a precursor to generate wind energy, is made. The possibility of generating wind power from these areas for various types of wind generators “WGs” are studied. In order to calculate power and energy, wind speed and temperature data in Egypt are studied. This study includes the evaluation of swept area, pressure, air density, power coefficient of the rotor, power, power density, scale and shape parameters, number of operating hours, energy, energy density and number of turbines. These data help in building wind farms with various types of generators using different rows of turbines far from the coast by different distances. Finally, all of these results are compiled in a new map of wind energy in Egypt. Egypt is also one of the Sunbelt countries that enjoy one of the largest potentials of solar energy applications. from 1991 to 2005, a solar atlas for Egypt was issued, concluding that the direct solar radiation intensity ranges between 1900 and 2800 Kwh/m2/y. The sunshine duration ranges between 9-11 hr/day with very few cloudy days. For this reason, this thesis aims to install solar Photovoltaic (PV) arrays throughout Egypt and calculate the electric energy and power that can be generated in Egypt from solar energy. The best electric and technical design for these arrays is studied. Therefore, Egypt is divided into several areas, a deep study for the ability of connecting each area with grid or using it as an isolated area is made, and this will be with different types of modules. Finally, the solar map of Egypt suggested to be developed to a new atlas that includes knowledge about average temperature, irradiance from sun, power and energy from each module, power and energy from the total area, number of modules and the economics of each area. |
