E4S: Enabling Interoperable Edge Architectures for Secondary Substations - Sylvain Mathiaud, Enedis & Erwann Roussy, Savoir-faire Linux

Wednesday September 16, 2026 13:45 - 14:15 CEST

Seebühne

E4S (Edge for Smart Secondary Substation Systems) is a DSO-driven Alliance developing vendor-neutral Edge specifications for secondary substations.

The initiative promotes an interoperable architecture that enables DSOs to integrate interchangeable components (whether proprietary or open source ones) while providing vendors with a common framework for innovation.

This session will present the E4S architecture and explain how interoperability and even interchangeability are pursued, by decoupling applications from hardware through:

- Open-source hardware abstraction solutions
- OSAL / PSL concepts enabling standardized access to specific devices whose drivers are not available in the Linux kernel

The presentation will be delivered by the lead and co-lead of the E4S Edge Node Software Working Group.
