Description: The ever-increasing penetration of power-electronic-based sources and loads in power distribution networks poses new challenges to the quality of electricity supply. This course intends to provide a systematic discussing on the modeling, analysis and measurement of harmonics in modern power distribution systems. The theoretical modeling and analysis on the harmonic impacts of photovoltaic (PV) inverters in distribution systems will be introduced first. New developments and concepts in determining and assessing the harmonic emission limits and, in particular the supraharmonics above 2 kHz will then be reviewed. Next, practical aspects of harmonic measurements and the impedance identifications of network and devices will be discussed. Lastly, the system-level harmonic studies in low-voltage (LV) distribution networks with PV and electric vehicles (EVs) will be presented. Each aspect is illustrated by real world examples.
The main topics to be covered include:
Organizer: Professor Xiongfei Wang - xwa@et.aau.dk
Lecturers: Dr. Jan Meyer, Technical University of Dresden, Professor Xiongfei Wang, and Dr. Ariya Sangwongwanich.
ECTS: 3.0
Time:13-15 JUNE 2022 NEW DATE 23-25 August 2022
Place: AAU Energy, Aalborg
Price: 6000 DKK for PhD students outside of Denmark and 8000 DKK for the Industry excl. VAT
Number of seats: 45
Deadline: 2 August 2022
Important information concerning PhD courses: We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 3.000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. We look forward to your registrations.
