CIGRECIGRE Paris Session 2026 · 23–28 August · Palais des Congrès

Published where the industry pushes forward.

APD Global's peer-reviewed research at CIGRE Paris Session 2026 - four study committees, one team. The engineers writing the papers are the ones commissioning the substations.

Several papers across study committees B3, B5, C4 and D2, spanning the most urgent engineering problems of the transition era - verified against the official technical programme and summarised below. Read the CIGRE Paris 2026 story →

Last updated: September 2026 · Refreshed each CIGRE Session (next: Paris 2028) and reviewed annually.

B3 - Substations and Electrical Installations

Paper 10389 · B3 PS1 · CIGRE Paris Session 2026

AI-Driven Solutions for Efficient Generation and Optimisation of Substation Designs in Brownfield Context

Authors: M. Surace, M. Richard - APD Global, Australia

Brownfield substation upgrades are the hardest design problem in the transition. This paper shows how AI-driven generative design and digital twins cut outage windows and de-risk legacy constraints - the method now applied on APD brownfield jobs.

B5 - Protection and Automation

Paper 10390 · B5 PS1 · CIGRE Paris Session 2026

Development of an IEC 61850-9-2LE-Based Process Bus Demonstration, Testing and Training Environment

Authors: R. Susanto-Lee, N. Nagoorsamy, D. Lange, J. Menzies, M. Surace - APD Global, Australia

IEC 61850 process bus is coming to every new substation. APD built its own testing and training environment rather than learning on a client's asset.

Paper 10392 · B5 PS2 · CIGRE Paris Session 2026

Using EMT Simulation in Reviewing Distance Protection with Inverter Based Resources

Authors: N. Nagoorsamy, M. Surace, M. Marquez - APD Global, Australia; V. Pillay - APD Global, New Zealand

Inverter-based resources can fool conventional distance protection. EMT simulation review - including replay into physical relays - finds the maloperations desktop studies miss.

C4 - Power System Technical Performance

Paper 10487 · C4 PS1 · CIGRE Paris Session 2026

Dynamic Modelling of Coordinated UFLS and DER Shedding in Wide Area RMS Studies of Non-credible Events

Authors: S. Nelson, J. Watson, A. Bruggemann - APD Global, Australia; J. Gao - AEMO, Australia

Co-authored with AEMO: how coordinated UFLS and DER shedding behaves across a 3,500-bus model of the NEM - directly relevant to any network owner planning emergency frequency schemes.

Compliance and Model Validation of a Grid Forming BESS Replacing Synchronous Generation: Real-World Integration into Australia's Northern Grid

Authors: B. Truong - APD Global / PWC, Australia; H. Lang - Heathydan, Australia; S. Cherevatskiy - Enerjia, Australia; V. Pillay - APD Global / PWC, New Zealand; S. Sproul - Hitachi Energy, Australia

Real-world proof that a grid-forming battery can replace synchronous generation - compliance and model validation on Australia's northern grid.

D2 - Information Systems, Telecommunications and Cybersecurity

Paper 11252 · D2 PS2 · CIGRE Paris Session 2026

Securing the Energy Transition: Cybersecurity Challenges and Solutions for Modern Digital Grids

Author: M. Surace - APD Global, Australia

The cybersecurity threats facing digital substations, and the practical mitigations - including post-quantum-era planning.
