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.
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
B5 Protection and automation
Subject: Communication Networks in Protection, Automation and Control (PACS): Experience and Challenges.
Using practical examples where possible, explain how the latest research and advancements in communications technologies can help improve the performance of PACS? What are the challenges preventing such technologies being implemented?
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?
C2 Power system operation and control
Subject: Capabilities Required for Future System Operation.
Frequency stability, ROCOF and frequency deviations are crucial topics in a low inertia power system. For real-time purposes can we implement an alarm that indicates to the control room operator that the level of inertia is critical?
C3 Power system environmental performance
Subject: Environmental impact of Energy Transition.
The environmental impacts associated with manufacturing and maintenance can vary depending on the technology. What’s the advantage of off grid solutions?
C4 Power system technical performance
Subject: Methods, models, and techniques for evaluating lightning, power quality, and insulation co-ordination to enhance the performance of the evolving grid.
What is the experience from operators/owners on discrepancies between expected and measured harmonic levels for large inverter-based generation parks? What strategies exists to minimise these differences and to avoid the installation of unnecessary mitigation measures?
C5 Electricity markets and regulation
Subject: Changing Role of Regulators and Standards.
What tools and methodologies are available and required by market participants to measure the risk levels of market participation in the context of their changing roles, penetration of variable renewables and other regulatory changes?
C6 Active distribution systems and distributed energy resources
Subject: Planning for Electric Vehicles and Demand-Side Response in Active Distribution Systems.
Which major factors should be considered when planning Active Distribution Systems in the context of increased DER such as Demand Side Response (DSR) resources and Electric Vehicles (EV)?
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?
D2 Information systems and telecommunication
Subject: New cybersecurity challenges in the changing electricity industry.
What are the key challenges of cybersecurity solutions for securing substation
