Objectives

Explain the operating principles of the main sources of renewable energy and identify the main topologies converting primary energy into electrical energy.
Explain and be able to apply the fundamental methods of control of the produced power.
Analyze and compare different topologies for the conditioning of renewable energy sources.
Identify, apply and verify the regulatory aspects of the basic interface of renewable energy to the electric grid.
Design and integrate the different subsystems, electronic and control, of the energy conversion chain.

Program

Eligibility for exams

According to the “Normas Gerais de Avaliação” and obtain a minimum of 40% in the weighted evaluation of the practical works

Calculation formula of final grade

The following Evaluation Components are considered:
1- Simulation work (TS), required
2- Experimental work (TP), required
3- Written exam (EX), without notes, with the duration of 2h

The Final Grade is calculated according to:
FG=0.2*TS+0.3*TP+0.5*EX
All components are evaluated in a 0-20 scale.
Course approval requires a minimum of 40% in the exam.

In any case, the evaluation is personal. The two works are subjected to a written report and an oral presentation.
The two works are made in group. TS measures the capability of analyzing, modelling and simulating renewable energy systems and control methods, as well as the creativity in the formulation of possible solutions.
TP evaluates the capability of designing, implementing and analyzing solutions, as well as evaluates the capability of team working. The oral presentation evaluates different aspects of communicating in public for a specific audience.
EX evaluates the capability of explaining and analyzing the operation of renewable energy systems based on different sources and control methods, as well as the level and robustness of the acquired knowledge and the technical-scientific merit.

Examinations or Special Assignments

None.

Special assessment (TE, DA, ...)

None. Simulation and experimental works can be done outside the course schedule. Practical works are mandatory for all course students.
Special students without practical classes’ attendance must do a final practical examination.

Classification improvement

Any part (TS, TP or EX) can be improved, in the established dates.

Observations

Prerequisites: basic knowledge of electrical machines and power electronics.
