22nd IERE General Meeting and 6th IERE Webinar

Toward Enhanced Resilience for Electric Power Systems

November 10, 2022, Webex

Power system instability caused by climate change, natural disasters, and human factors such as cyber attacks is a serious threat not only to our living environment, but also to the survival of life in the event of a large scale power outage. This webinar will introduce the latest technologies and countermeasures that are being researched and developed to improve power system resilience.

Q&A — Typical QuestionsThe day was filled with many questions and a lively Q&A session.

(W-1) Research Needs for Electric System Resilience

Is V2G already possible (from a regulatory point of view) in the US?
Here in most EU countries, there is not yet a regulatory framework and this seems to be a harder hurdle to tackle than the technical ones... Are you doing better in the US?
Should Resiliency be promoted at the same time as Decarbonization and Digital Transformation, or should it be considered as a countermeasure to these?
Extreme weather and climate change including hurricanes, heatwaves, heavy snowfalls, etc. is different worldwide.
Does the EPRI’s new Resilience project “CLIMATE READi” adapt only to the USA? How does it adapt in other countries?

(W-2) The wide frequency measurement technology for Inverter based power system
—Improvement of awareness capability of resilient grid

What does WFMD mean?
Does WFMD combine three methods (PMU, M&C, and Power Quality)?
What is the objective of this development? To improve resilience in the case where renewable energy is connected to the grid through inverters? Are there any other possible positive impacts of adopting this method?

(W-3) Flexible Power Transformers to Improve Resiliency of Transmission Networks

What are the most important points of the several guidelines listed in the design of Flexible Transformer?
Could you share with us the overall cost differential for these types of flexible transformers vs traditional designs?

(W-4) Climate change adaption, new challenges for Substations Equipment Applications

In the "Climate Change Adaption”, “Development of Resiliency Measures" would be the most important. Are there any specific studies being conducted by Powertech Labs?
Most of this presentation is related to substations and transformers. Is it understood that they are important equipment for grid resiliency? What do you think?
