New Constraint Management Techniques for Meshed Transmission and Active Distribution Networks

An Online Technical Webinar

Wednesday 9th December 2020 | 12.30 to 13:30


Constraints on the Transmission network are costly, requiring potential capital investment in the longer term, and in the short term output management of generators in areas impacted by these constraints. In the UK, on average between £1m and £2m per day is spent in payments to generators, connected customers and others to ensure that overall integrity of the Transmission network is maintained. Issues such as thermal capacity, stability criteria such as voltage and dynamic all must be managed and can impact on constraints.

There are many techniques for minimizing constraints usually based on traditional analysis and network management, but System Operators throughout the world are looking to find other techniques to minimise the costs while maintaining the expected reliability and resilience.

Topology optimisation is a software technology that finds grid reconfiguration options which may lie deep in the network to route flow around congested/overloaded facilities and that would not be identified using current techniques.

These reconfigurations, implemented by opening or closing selected circuit breakers, enable power flow control using existing equipment and increase the utilization of meshed transmission and distribution network.

By optimally adapting the grid topology to meet system conditions and needs, the transfer capabilities increase in the desired directions, providing significant cost savings and reliability and resilience improvements to consumers. This presentation will illustrate the technology principles and discuss its impacts using case studies conducted with National Grid ESO and system operators in the US.

Typically, we find increases in available transfer capacity of over 10%, load shedding relief under emergency conditions and extreme events, reductions in renewable curtailments, and congestion cost savings of over 50%.

Lightning Phenomena in the Alpine Region of Austria – Lukas Schwalt

In the first part of this presentation, an introduction about thunderstorm formation and lightning physics will be given and secondly the key findings of Dr. Schwalt’s PhD thesis “Lightning Phenomena in the Alpine Region of Austria” will be presented. The motivation for the PhD thesis was to gather lightning ground truth data for Austria out of on-site measurements, because this area shows high lightning activity. For this purpose, real processes of cloud-to-ground flashes were recorded with a high-speed video camera and an electric field measurement system. Analyses of this exclusive data set provide insights about lightning characteristics in general and for the alpine region in particular.


Effect of Network Parameters on the Transient Over-Voltage Phenomenon During System Restoration – Diptargha Chakravorty

System restoration is currently a transmission-led approach of starting large conventional generators with self-start capability and energising a skeleton network. Increasingly, transmission connected fossil-fuelled generators are decommissioned around the world to meet the emissions targets. This makes it imperative to explore the possibility of using distribution connected DERs to support the whole system restoration.  However, energisation of network elements such as circuits and transformers pose significant challenges such as switching transients, Temporary Over Voltage (TOV) etc which can reduce the available options to restore a network and lead to a higher number of circuit breaker switching to avoid damaging equipment. This presentation will discuss the impact of different network parameters such as the strength of the system, saturation characteristic of transformers etc on the TOV and ways to manage it during restoration.



Lukas Schwalt is a CIGRE NGN AT member and he is a Post-Doc researcher at Graz University of Technology, Institute of High Voltage Engineering and Systems Performance. After completing his master in Electrical Engineering at Vienna University of Technology, he successfully defended his PhD thesis “Lightning Phenomena in the Alpine Region of Austria” at Graz University of Technology in 2019. His main areas of research include cloud-to-ground lightning, measurements of lightning discharges, performance of lightning detection systems, lightning protection concepts and transient voltages on power lines. He is also involved in the Austrian Association for Electrical Engineering in the field of lightning protection, CIGRE B2 and C4 and served as the technical secretary for „CIGRE International Colloquium on Lightning and Power Systems ICLPS 2019” in Delft, Netherlands. He was awarded the “Young Scientist Award” at the International Conference of Lightning Protection ICLP in 2018.

Dr Diptargha Chakravorty is a Senior Consultant with TNEI Services. He is an electrical engineer with over 8 years of experience in the power industry, including a 4-year PhD on the impact of demand response on system stability from Imperial College London. He specialises in modelling and analysis of transmission and distribution networks and automation of system studies. His core expertise includes stability analysis, grid integration of renewable energy and power electronics converter control. He is currently the vice-chair of the Cigre UK NGN steering committee.

WPD Primary Network Power Analysis (PNPQA) Project Interim Findings

An Online Technical Webinar

Wednesday 4th November 2020 | 12.30 to 13:30


 Western Power Distribution’s (WPD’s) Primary Networks Power Quality Analysis (PNPQA) project aims to reduce uncertainties around the power quality (PQ) within primary distribution networks and facilitate increased integration levels of low carbon technologies (LCTs). The project is funded via Ofgem’s Network Innovation Allowance (NIA) and is achieving its aims through implementing a monitoring and analysis system for assessing the PQ and harmonic content of waveforms in distribution network, verifying the accuracy of the network equipment used for PQ monitoring, and using modelling to predict the future PQ impacts of increased integration of LCTs.

This webinar will provide you an insight into the project and some of the findings gathered so far, including:

• Temporal and spatial variations of power quality across a distribution network.

• In-situ power quality characteristics of LCTs including solar PV, energy storage, wind, and electric vehicle (EV) charge points.

• Power quality changes seen through the COVID-19 response.

• Results of laboratory testing of the harmonic response of voltage transformers used for power quality monitoring.

• Development and use of a vendor-agnostic common platform for combining power quality data from multiple monitors.

Stress and Anxiety at Uncertain Times

Dealing with Stress & Anxiety in Uncertain Times – An Online Webinar

By | Blog, Webinars | No Comments

Have you ever…

  • Over-thought a decision?
  • Over-reacted to a situation?
  • Felt nervous?
  • Beat yourself up for making a mistake?
  • Felt stressed?

If you have answered yes to any (or all) of the above, you are in good company. Try everyone.  But do you know why you experience unwanted thoughts, feelings and behaviours; and what you can do about it?

In this 90 minute webinar, we are working with chartered psychologist Dr Robbie Anderson of Chimp Management Ltd to explore the science and practical management of stress and anxiety.

Attendees will have the opportunity to:

  • Learn why and how the brain reacts to uncertainty by creating worry and stress responses.
  • Explore practical approaches for dealing with stress and anxiety.
  • Ask or listen to questions answered by an expert in this field.

For people who already feel in a great place, this session could be a great opportunity to consider how you can further support the health, wellbeing and success of others.
