POWER PRODUCTION FROM RENEWABLE ENERGY AY 2022-23 5th February 2024 Prof. Andrea Giostri Time: 1.5 hours NAME and SURNAME:.................................................................................................................................................. COURSE and CFU:......................................................................................................................................................... Instructions for the examination: 1) Clearly indicate your name on all the sheets you will deliver. 2) The score refers to exercises done in a comprehensive manner with exact numerical results. Numerical results correct but not accompanied by explanations will not be taken into account. The final score can be normalized according to the average results. 3) Answer briefly and clearly only to the asked questions. Calculations and explanations which do not respond to the questions will not be considered for evaluation even if correct. 4) Talking with colleagues and / or cheating will cause the cancellation of the exam. 5) All the needed data for the resolution of exercises lies on this paper. It is NOT ALLOWED to use material other than this (e.g. books, clipboard etc.). Exercise 1 (15 points) Compute (i) the size of a CSP parabolic trough solar field using synthetic oil as Heat Tran sfer Fluid (Tmin 290°C - Tmax 390°C) and a steam cycle for the conversion of the thermal power into electric power (5 points). The plant is equipped with a thermal energy storage. Design solar radiation is characterized by 960 W/m2 Global Horizontal Irradiation and 150 W/m2 Diffuse Horizontal Irradiance and zenith and azimuth angle of the sun for design is equal to 25° and -15° respectively. Neglect the ground albedo. The plant characteristics in nominal…
