The next SC B5 Colloquium will be held in Tromso in Norway in the last week of June 2019.
The latest Technical Brochure published by SC B5 is “Control and automation systems for Electricity Distribution Networks (EDN) of the future.”
The objective of the Joint Working Group (JWG) C6/B5.25/CIRED is the control and automation systems for the future electric networks with particular reference to the TSO/DSO interface.

The Technical Brochure written by JWG is mainly focused to evaluate the level of automation and control necessary to better manage distribution networks with large penetrations of Distributed Energy Resources (DERs), as seen from both the Transmission Systems Operators (TSO) and Distribution System Operators (DSO) perspectives, and to provide services and information about the two level of management (i.e. at TSO and DSO level).

The brochure can be downloaded free of charge by CIGRE members from the e-Cigre web site and can be purchased by non-members
