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


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