ANALYSIS OF INNOVATIONS IN CONCENTRATION OF SOLAR RADIATION

As part of my research work carried out successfully at the level of Master 2 in 2016, in the laboratory of Electrical Engineering, Mechatronics and Signal Processing, I designed a TVS central, which allowed me to replace the use of diesel fuel by solar energy in the production of electrical energy. This solar power plant was named: TVS system. Its solar energy collector is parabolic and well suited to urban areas. I have noticed that its installation, operation and maintenance are complex and require good training for officers working at the plant. The rural area is not electrified in Cameroon it has been very interesting to extend the use of the TVS system in rural areas since water and the sun being available in these places, it will work with steam which will allow to have a kW at lower cost. It will be a question for me in the context of performance research in the production of electricity, to redesign the TVS system with innovative solar energy collection equipment which also allows to add a thermal storage system to overcome lack of sunshine at night. The process of producing electricity from solar radiation is complex for concentrated solar energy, but direct for voltaic panels. Since the solar energy is not very dense, it is necessary to concentrate it to obtain exploitable temperatures for the production of high-power electricity. These sought temperatures are between 400 ° C and 600 ° C. Figure 1 below shows the capture of solar radiation and the movements of the thermal energy received until its transformation into mechanical movement driving the alternator. The solar energy production sector has become dynamic all over the world and we are witnessing various promising innovations which will announce the primordial place that renewable energies will occupy in the near future. Today, solar energy is estimated at 19% of the world's electric energy. During my thesis work, I propose to analyze Today, solar energy is estimated at 19% of the world's electric energy. During my thesis work, I propose to analysis of innovations in concentration of solar radiation [10]
