Electrical Power Systems

#### Mandatory Courses

The three mandatory courses at DTU during the fall period have a total of 30 ECTS. Therefore it is not necessary to follow an elective during the January period, however you can always choose to do so anyway.

##### Wind Turbine Technology and Aerodynamics (10 ECTS)

This is the only course you will do with the other EWEM tracks. It gives a good overview of all the various concepts involved in the design and functioning of a wind turbine. The course is divided into different sections with two assignments. One part of the course is all about the mechanical concepts of a wind turbine and the part is all about the electrical concepts. This course demands a decent knowledge and experience in programming. Two 4hr blocks a week and the lecture mainly comprises of introduction to the concepts and working on assignments or exercises for the rest of the period. Lecturer is technically sound with the concepts and gives proper guidance and assistance with the assignments and exercises. Evaluation is based on the two assignments and a 4hr long exam based on the assignment and exercises done during the lecture sessions.

##### Power Electronics 1 (10 ECTS)

In the course of Power Electronics you will learn about the different parts of a DC-DC power converter. After each lecture about a different subject you need to write a report with your group. In these report you will theoretically design a component for a converter. These reports will be peer reviewed by another group. In total you will write 4 reports which will be combined into a big final report. The exam will be oral individually in which the professor will ask questions about your design. This will focus on the parts which you have written.

During the January period it is possible to follow Switch Mode Power Supply 2 during which you will actually build your designed power converter.

##### Introduction to Electric Power Systems (10 ECTS)

During this course you will learn how an AC grid works. The course has two parts, the theoretical part and the project part. Normal lectures are given about different components in the grid, such as transmission lines and transformers. Different methods to model these systems are explained. Every two weeks you will need to hand in exercises on Maple TA to be able to participate in the exam. These exercises are not to difficult if you follow the lectures.

In parallel to the lectures you will work on a group project. During this project you will design a power grid for an area which you can choose freely (with some requirements from the project description). In a computer program you will then simulate and test your power grid. You will have to give a midterm presentation and a final presentation. Also, you will need to write a report about your power grid.

#### Approved Elective Courses

* Wind Turbine Electrical Design (10 ECTS)
* Stability and Control in Electric Power Systems (10 ECTS)
* Transients in Power Systems (5 ECTS)
* Integration of Wind Power in the Power System (5 ECTS)

### Semester 2 - TU Delft

At TU Delft 3 different profiles are suggested. However, you can always ask to do different courses instead. If you follow a suggested profile, you will still need to choose an elective, since all the profiles contain 27-29 ECTS. One course is mandatory and is in all profile (Transients in Power Systems). The profiles may be updated over the years but can be found here (https://studiegids.tudelft.nl/a101\_displayProgram.do?program\_tree\_id=25267)

#### Mandatory Courses

##### Transients in Power Systems (4 ECTS)

Good luck, because it is mandatory! Though, it seems a bit difficult in the beginning, but it is not. Recommend to watch recordings. Look at the old exams. These are similar from year to year. The book is also helpful.

#### Courses in the Profiles

##### Electrical Power Systems of the Future (4 ECTS)

The course highlights the challenges of the grid of the future. The lecturers are knowledgeable, as one of them has been working at Tennet on grid design for 35 years. There are weekly exercises.

##### Power Electronics (4 ECTS)

This course delves deep into resonant converters and power electronics. The lectures are hard to follow as the professor goes through the slides quickly, which are screenshots of the book. Once you look through the book it is actually a nice topic. There are plenty of old exams and with these the exam is doable.

##### Electrical Machines and Drives (4 ECTS)

EMD will be given during the 2nd quarter at TU Delft. You will need to follow the lectures only on collegerama. Also you will need to do some practical assignments in the lab. You will need to contact the teaching staff to make an appointment for this. If you do not choose to follow an elective during the January period at DTU you can ask if it is possible to do to the exam at the end of January. However, it is quite some work to do all the assignments and lab session in a short period. But it can save a lot of time later at TU Delft.

The course itself consists of 5 weekly assignments about DC machine, Induction Machines and Synchronous Machines. Also about each of these machines a lab session will conducted. You will need to prepare for these lab session to show you have enough knowledge to operate these machines. After the lab session you will write a report about the your findings. You will need to finish all of these reports and assignments to able to make the exam.

##### Power Electronic Components (4 ECTS)

This course has a lot of contents, with weekly assignments, an exam and a presentation. When we started it seemed like a lot of work in one quarter, but now they have spread it over both quarters.

##### DC and AC microgrids (4 ECTS)

Nice and easy-paced subject, with two group assignments and a simple exam.

##### Power System Dynamics (4 ECTS)

An in-depth course on non-steady state behaviour of the grid, with weekly lab sessions in PowerFactory. The lectures are long, but it does have a lot of information.

##### Intelligent Electrical Power Grids (4 ECTS)

Nice introductory course to all other courses within the IEPG group. Each lecture has a different lecturer that will highlight some part of the IEPG group. There are weekly assignments, which are quite a lot of work but the exam is an easy multiple-choice exam.

#### Approved Elective Courses

##### Uncertainty modelling and risk assessment in electrical power systems (4 ECTS)

**Electric Vehicle & Charging Technology (4 ECTS)**

It is a nice course, which goes into all elements of electric vehicles. There is a lot of content, with an online course (MOOC), group assignment, exercises and lectures. There is some mechanical engineering as well with torques, forces and gear ratios.

**Co-simulation of Energy Systems (4 ECTS)**

The course is more of a theoretical introduction to the methods that are used when we need to solve an energy problem (e.g. choose the cheapest dispatch generation) that involves different subsystems. For example when we want to built an energy market we need to combine real data (generation, demand), with a software that makes power flows and calculations, then the results of the power flow should be sent to an optimisation algorithm and a decision should be taken. All these steps have an hierarchy. The point of this course is to describe this hierarchy. Sometimes the course was a bit boring but if you get the point then it’s interesting and practical. Co-simulation has no written exams but a team project. The project is a bit vague because the professor prefers to built the project from scratch, while he is not providing any clue for the implementation. Teamwork and brainstorming is important for this project. If you are working in a good team then it would be fine.
