The course aims to introduce the topic of electrical power generation related to renewable energy resources available on the earth’s surface. The course provides the classification of the renewable sources and their characteristics, the description of equipment and devices involved in the energy harvesting and conversion process, the discussion on the most common regulation strategies for extracting maximum power from the sources and for island operation or connection to the electricity grid. The students will acquire the skills necessary to understand the modes of operation of the systems used for electrical power generation from renewable energy resources available on the earth’s surface.

Prerequisiti
Basic knowledge of mathematics and physics normally acquired in first-cycle degree programmes is required, with particular reference to the concepts of force, energy, power, pressure, and conservation of momentum. Elementary knowledge of fluid mechanics and atmospheric dynamics is also useful, where already acquired within the study programme. No specific prior knowledge of wind turbines or wind energy system design is required. No specific formal prerequisites are required for the part of the course devoted to wind energy, except as otherwise provided by the academic regulations of the degree programme.Core Documentation
Sharpe, David, et al. Wind energy handbook. Vol. 355. Wiley, 2013.Attendance
Attendance for the part of the course devoted to wind energy follows the provisions established by the academic regulations of the degree programme and by the overall course in which the module is included.Type of evaluation
The assessment of the knowledge and skills related to the wind energy part is carried out within the final examination of the overall course and consists of one open-ended written question. The question focuses on the physical and technological principles covered during the lectures and may require, in addition to the description and discussion of theoretical topics, simple quantitative considerations or the interpretation of diagrams, characteristic curves, and data related to wind energy systems. The assessment is intended to verify: - knowledge of the main concepts related to the wind resource and wind turbine operation; - the ability to explain the principles of wind energy conversion, actuator disk theory, and, at an introductory level, BEMT; - the ability to apply fundamental relationships to simple problems involving power and performance estimation; - the ability to qualitatively interpret the main parameters affecting wind turbine and wind farm design; - the ability to discuss the main energy and economic implications of a wind energy project; - the clarity, correctness, and appropriate use of technical and scientific terminology in the written answer. The level of detail required is commensurate with the duration of this part of the course, corresponding to 1 ECTS credit. teacher profile teaching materials
