To submit a contribution, you must be duly registered to the Virtual Centennial Session. It implies that your effective payment is received by CIGRE Central Office ahead of your submission.

Because this year the Session is virtual, the contributions should be submitted to the Study Committees earlier than for a face to face Session.

The calendar below shows the different dates set up by the 16 Study Committees to manage the contributions of their Group Discussion Meetings (GDM).

These dates may differ following the internal organisation of each Study Committee and the dates of its Group Discussion Meeting in the Session.

Share your expertise!

The CIGRE knowledge development methodology for the CIGRE session is about sharing and developing power system expertise. As is our custom our Special Reporters (SR's) have been studying the numerous papers presented around our preferential subjects at the 2020 e-session. The SR's have developed a series of key questions around which contributions are invited.

To provide a taste of the direction of this thought leadership event we have provided below one example question for each of our 16 domains of work. Follow the link for your chosen domain of work to view the full range of questions and relevant special reports.

If you would like to contribute your expertise the deadlines are approaching so please move quickly. You can view the dates here (please scroll down the page).

Group A – Equipment

A1  Rotating electrical machines

Subject: Generation mix of the future.

When Battery Energy Storage Systems (BESS) are used, in a certain system where the use of non-dispatchable energies requires the installation of synchronous compensator (SC),  what directions should be taken to dimension the power of BESS’s and their location to be installed?

A2  Power transformers and reactors

Subject: Transformer technologies to enable integration of distributed renewable energy resources.

Due to the problems associated with the integration of renewables, what changes are required in the transformers specifications to ensure that they will perform satisfactorily?

A3  Transmission and distribution equipment

Subject: Future developments of transmission and distribution Equipment – SF6 Alternatives.

Different gas mixture applications use different mixture percentage which could vary among different manufacturers. From final users’ standpoint this could lead to possible refilling mistakes in case circuit breakers from different manufacturers are installed in the same 10 substation. Is it imaginable to define a commonly agreed mixture?

Group B – Technologies

B1  Insulated cables

Subject: Cables for future power systems

Is standardisation of accessories likely to occur in HV DC systems? If so, how would such standardisation entail?

B2  Overhead lines

Subject: Resources and design considerations.

What is the next frontier for live-line work? What can’t we do today that technologies under development will allow maintenance team to do in the future?

B3  Substations and electrical installations

Subject: Substation design and technologies.

With the drive to achieve ‘Net zero by 2050’ or earlier… what will be the key issues to manage? What role do economics or legislation play in the future of substation design and operation?

B4  DC systems and power electronics

Subject: HVDC systems and their applications.

What key technical aspects should be considered and assessed if an existing HVDC-LCC

transmission scheme is to be paralleled with a newly proposed HVDC-LCC/VSC supplied by

different manufacturers?

Group C – Systems

C1  Power system development and economics

Subject: Energy sector synergies for decarbonising efficiently.

What technical and market measures are available to facilitate the smart charging of electric

vehicles that is expected to become the societal norm?

Group D – New Materials and IT

D1  Materials and emerging test techniques

Subject: Functional Properties and Degradation of Insulation Materials.

Apart from SF6 alternatives, what examples are there of reducing the carbon

footprint of products through the use of new materials, production processes or recycling in the transition to a Net Zero world? Can these changes be quantified?
