Tutorials
Tutorial sessions offer an excellent opportunity for training and development in power quality topics ranging from fundamental concepts to state-of-the-art developments.
Tutorials are scheduled on August 31 in the time from 14:00 to 17:30 including a coffee break of 30 min.
Tutorial Track 1
CIGRE TB976 – Methods for Identification of Frequency Response Characteristic of Voltage Measurement Systems (1,5h)
Presenter: Dr.-Ing. Erik Sperling
This tutorial summarises the CIGRE technical brochure (TB 976) regarding the frequency response of voltage measurement systems in modern networks. It explores the design and accuracy of conventional (inductive and capacitive) and low-power instrument transformers (voltage dividers and optical sensors). Key performance characteristics, like ratio error, phase displacement, and resonance frequencies, are examined alongside mathematical modelling techniques such as vector fitting and digital twins. Additionally, grid requirements and performance characteristics are discussed and considered. Modern test technologies are provided for identifying the frequency-dependent transmission behaviour. Finally, the tutorial provides a classification mapping to help professionals identify measurement requirements, grid characteristics and future power system applications to select the best instrument transformer technology.
The impact of Geomagnetically Induced Currents on Power Quality (1,5h)
Presenters: Dr.-Ing. Roger Alves de Oliveira, Dr.-Ing. Rafael de Souza Salles and Prof. Math Bollen
This tutorial explores geomagnetically induced currents (GICs) and their impact on power quality. It covers measurement results, monitoring methods based on measurements, geographic validation studies from research conducted by the speakers. The main goal of the tutorial is to explain what causes geomagnetic disturbances, how they affect power quality, and mainly on how to detect them from PQ measurements. The tutorial provides a practical workflow for understand the PQ variations and events during geomagnetic disturbances.
Tutorial Track 2
Decomposition into Currents’ Physical Components (CPC): the Fundamental of Power Theory and Compensation (1,5h)
Presenter: Prof. Leszek S. Czarnecki, Louisiana State University
This tutorial introduces the Currents’ Physical Components (CPC) decomposition as a framework for understanding power properties in electrical circuits with nonsinusoidal voltages and currents. It examines the physical phenomena responsible for energy transfer degradation in complex systems, including single-phase and three-phase circuits with nonlinear or unbalanced loads. The session focuses on how the CPC method facilitates the development of reactance and hybrid switching compensators to improve system efficiency. By addressing long-standing theories and utilizing practical numerical examples, the tutorial provides a comprehensive approach to investigating and optimizing power properties in modern electrical grids.
Electric Vehicle Charging Systems: Power Quality, Metering Accuracy, and On‑Site Verification (1,5h)
Presenter: Dr.-Ing. Angela Espin-Delgado
This tutorial addresses the technical challenges of ensuring reliable energy metering and power quality monitoring in modern electric vehicle charging systems. It explores how realistic grid conditions, such as network disturbances and network impedance, can affect charging efficiency and meter accuracy. Participants will learn about advanced laboratory test benches for AC and DC charging systems up to 44 and 350 kW, respectively, the use of load emulators for reproducible testing, and new on-site verification procedures designed to meet international legal standards. The session provides practical guidance for professionals to navigate emerging metrological frameworks and improve infrastructure performance.
Tutorial Track 3
Understanding the Stochasticity of Harmonic Impedances and Injections for Hosting Capacity Calculation (3h)
Presenters: Dr.-Ing. Amauri Martins Britto, Dr.-Ing. Jinwen Xiang and Prof. Hakan Ergun
This tutorial explores the technical challenges of large-scale industrial electrification driven by the European Green Deal. As industries integrate high-power electrical drives and power-electronic converters, rising harmonic distortion threatens grid stability and industrial productivity and competitiveness. The tutorial introduces methodologies from the HARMONIC project to assess harmonic hosting capacity. Key topics include uncertainty quantification for cable impedances, harmonic phasor distributions of power converters, and optimisation-based stochastic harmonic hosting capacity determination. This tutorial will guide participants from component-level uncertainty to system-wide hosting capacity assessment, equipping them with the analytical tools needed to model various aspects of harmonics in the power system.
