In the new paradigm of energy and digital transition, the system automation designed for smart grid applications must be adapted to cater for new functional and reliability needs. To avoid significant increasing operating expenditure, the devices will therefore need to be updatable, configurable, and supervisable remotely. This is a cornerstone of the solution we call "System Management" (SM), which refers to functionalities that are not directly linked to the operational role of the equipment but allow it to perform its operational functions in the best conditions possible. This paper presents the ongoing EDF's work on system management. To face the challenge of a widespread deployment and interoperability, EDF R&D is developing a first System management prototype tool. The goal is to build an interoperable and vendor independent system, homogenous with the core 61850 primary functions of the equipment.
