- It is difficult to understanding what Tuan is saying and it is hard to follow all his slides. there are to many. Also if I dont understand something he talks about and ask him about it in the break, he explains it in exactly the same way as he told on the lecture so i still don"t understand afterwards.» (Small extent)

- the primary book sucks badly, no information about whatever I was felt I wanted to find in it» (Small extent)
- Tuans handouts and notes were good in general. But the frequency regulation topic was not well covered by the text. When it comes to voltage stability, Nayeem was poorly structured, and the notes terrible. They were badly written and hard to read. Some words could not be read at all. The first book on the recomendation list of course literature, I can not recomend for oher students however. It was too heavy to read.» (Some extent)

- It was very frustrating when the program didnt work at first, and the tasks were not very educational, just testing about with different values. We foucused more on the report, but havent heard about it at all.» (Small extent)
- It was badly structured. There should be clear instructions from the beginning of what is expected to do. It seamed that the the teachers exppectations from the students decreased with time.» (Some extent)
- Digsilent is not a user friendly software, but Mercia had managed to communicate the concept of voltage stability. She was encouraging, helpful but the choice of the software is the problem. » (Some extent)

- It is all very general about every subject and with quite poor study material and not that many exercises. Better to have one course just about stability and protection, and skip the economy part. That part could be included the other course about the electricity market.» (Poor)
- more content, about power quality and protection for example» (Fair)
- In this course Tuan"s lectures were easier to follow and more intresting then in the PSA. Unfortunately, it was quite difficult to follow Nayeem during the tutorials, he didn"t present the solutions very clear. » (Adequate)
- The variety of subjects was very interesting but not enough depth in some aspects (such as the modeling of the system and the protection part) I know that the timeline was tight , but I suggest to offer courses that deal with these areas (at least the protection)» (Good)

20. What should definitely be preserved to next year?

- The digsilent lab is good for understandig but maybe not the best thing for a project, it takes too long to learn the program.. And the lab»
- All the topics covered in the course were very essential»
- the visit study, »
- Study visit, the lectures in Volatge stability, protection, Fredquency control»
- The dialect english speaking of the lecturer was bad and the tutor was terrible.Attending in the tutoring class were vasting our valuable times.»
- Voltage stability and frequency»
- ELD, UC, Frequuency control, transient & voltage stability,protection»
- everything»
- The course content is great and the subjects are related nicely to one and other. Tuan is a great teacher.»
- the DigSilent project is not bad, but needs better guidance and more clear goals. The Aristo simulation is also good to see. »
- everything taught »
- the whole thing »
- Aristo demonstraion was well performed and should be preserved.»
- The study-visit, the worked out examples.»

21. What should definitely be changed to next year?

- more info in the course»
- Maybe something more calculations on different types of relays»
- Electric power engineers are expected to have a good knowledge of Protection. I feel Power system protection should be introduced as a separate course together with power system design.»
- tutor"s hand writing.»
- The reading materials for Voltage stability»
- I think more detail in Protection and power quality»
- tough numerical methods like euler involving labourous calculations»
- more indepth study.»
- I would like more dynamical examples during some abstract theory and more examples to "the real world".»
- Like I stated above, better and more reading material on frequency control and MUCH better reading material on voltage stability. Maybe a short description of the parts in the general control of the power system, like SCADA and such things. And a deeper coverage on protection, or a new course covering the topic in more detail.»
- DigSilent»
- I think it would be great if is possible to include some very important topics in Power Operation like Contingency Analysis and State Estimation because these topics are very important in modern Energy Management System. The protection part can be replaced by the above topis and it would be good if it can be treated as individual subject to taught by expert from industry.»
- nothing »
- less slides, more use of the board. »
- digsilent project should be changed so that student can learn more about the software»
- The content could be extended. Tutors need to present ALL steps on the black board. Please correct all typing errors and miss prints!!»
- The handwriting of the tutor on the tutorials. I have not seen anyone write that bad before.»
- The handwriting on handouts and the board needs some improvement. (Don"t take this as an insult because I know my handwriting is often almost unreadable for others, too, but if other people shall read something you have to put more effort in writing clearly!)»

22. Additional comments

- Very interesting course»
- The more demostration and pratical methods be included than extensive theoretical work»
- I would like to thank the whole course Team: Tuan , Nayeem and Marcia.. I realy apriciate all your efforts Thank you»
- For the theoretical part I do suggest to have some kind of oral exam rather than the traditional written exam.»
- Distributed handouts and black board writing SHALL BE READABLE, Please!!»
