Tutorial 1: New developments in grounding design including risk analysis


In this tutorial, the essential aspects for the dimensioning and assessment of earthing systems, especially for distribution networks (medium and low voltage networks), will be covered.

First, the assessments according to international standards such as EN 50522 and IEEE Std. 80 will be compared with the newer assessment approach based on Quantified Risk Analysis (QRA).  Furthermore, the most important parameters for safety assessment, such as fault duration, fault probability, magnitude of fault current, earthing resistance and transferred voltages are addressed and discussed, including case studies. 

The determination of reduction factors and the role and proof of a global grounding system are discussed.

Tutorial 2: Measurement and evaluation of 2-150 kHz disturbances (supraharmonics) in distribution networks


This tutorial comprehensively covers all aspects related to the measurement and evaluation of supraharmonics in the 2-150kHz frequency range.

It covers typical characteristics of intentional and nonintentional emission, the measurement uncertainty including the suitability of sensors, measurement algorithms/methods, as well as the present status of standardization. Some challenges in practical grid application are presented using field measurements.

Finally, the importance of impedance for understanding the propagation of supraharmonics is described and illustrated by the results of measurements taken in LV networks in different European countries.

The findings presented in the tutorial are majorly the outcome of the EU funded EMPIR programme project SupraEMI about the definition of a new normative measurement method for the 2-150kHz frequency range for a future edition of IEC 61000-4-30.

Tutorial 3: The connections of Distributed Energy Resources (DER) into unbalanced three-phase MV and LV networks: challenges and solutions


Achieving the long-term climate targets will require decarbonisation of power, transport and heat. As a result, the society will have much higher dependency on electricity.

New electrical demand from heat and transport can double or even triple the existing peak load. This will impose unprecedented stress on the existing electricity distribution networks, especially the low voltage (LV) distribution networks, by pushing these networks to their capacity limits.

LV network phase imbalance aggravates this stress by wasting network capacity, further constraining the connections of distributed energy resources (DER), electric vehicles (EVs) and electric heat pumps (EHPs) and ultimately compromising the decarbonisation agenda.

Tutorial 4: Network pricing for smarter electricity distribution networks


Increased operational efficiency and growing low carbon technologies in electricity distribution networks challenges the status quo in network pricing methodologies.

These methodologies largely reflect the passive nature of the traditional distribution system with steady load growth and limited active network and customer devices.

The smarter distribution networks have increased operational intelligence but have to accommodate growing and uncertain electric transport and heat load.

This tutorial introduces the current practice in network pricing in the UK, Germany, Brazil and United States their impact to traditional and new network customers, and improvements made for the distribution networks to accommodate low carbon technologies swiftly and cheaply.
