Welcome to Managing Harmonic Emissions in Modern Distribution Power Grids


The ever-increasing penetration of power-electronic-based sources and loads in distribution power grids poses new challenges on the quality of power supply. This course aims to provide a systematic and holistic discussion on different aspects related to planning, modelling and measuring harmonics in modern distribution power grids. New developments and concepts in determining and assessing emission limits for power electronics based customer installations are discussed. Practical aspects of the harmonic measurement and data analytics in active distribution networks will be discussed, and particular attentions will be given to the challenges of increasing measurement points and data amounts. The theoretical modeling and analysis on the harmonic impact of photovoltaic inverters and electric vehicle chargers in low-voltage (LV) distribution systems will be discussed. Each aspect is illustrated by real world examples. The main topics to be covered include

- Grid codes and compliance assessment for customers with power electronic based sources and loads
- Harmonics measurement techniques and suitability of voltage and current transducers
- Power quality data analytics with special focus on large data amounts
- Harmonic modeling, analysis and measurement of photovoltaic inverters and electric vehicle chargers in low-voltage distribution networks
- Practical implementation issues for harmonic grid simulations in frequency domain

Prerequisites: Prior knowledge of power electronics fundamentals, digital signal processing, and power systems is preferred.

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 5,000 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 three 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.
