IEC 61850 in the Joint EURELECTRIC-EDSO Smart Grid Position Paper

The “Union of the Electricity Industry” (EURELECTRIC) and “European Distribution System Operator for Smart Grids” (EDSO) have assigned a very high priority to the application of IEC TC 57 standards, e.g., IEC 61850, CIM, IEC 60870-5/-6, IEC 62351, … in the paper “DSO PRIORITIES FOR SMART GRID STANDARDISATION”.

End of January 2013 they have published a comprehensive position paper on the standardization for smart grids:


A key clause puts IEC 61850 on a high priority (excerpt of one example):

3.3. Extended field data modelling standards (IEC 61850) to support demand response, DER and VPP

”While the IEC 61850 standard was originally addressing applications and communications within the substation, recent work is being undertaken for extending its applicability to distribution automation applications integrating field devices located outside the substation fence. With its object oriented structure, IEC 61850 can provide comprehensive and accurate information models for various components of distribution automation systems, as well as an efficient solution for this naturally multi-vendor environment.
Some typical applications include: Volt/Var Control (VVC), Fault Localisation, Isolation and Restoration (FLIR), Outage Management System (OMS), Distribution State Estimator, Distributed Generation and Demand response Management, Load Forecast and Modelling (LFM), and other.
IEC 61850 is the only international standard for substation automation which is open for future application. Currently IEC 61850 is extended for use outside substations. The use cases of the different distribution automation concepts need to be considered in the information data models. Therefore the IEC 61850 data models shall cover all distribution automation objects. IEC 61850 allows an open and flexible design and operation of communication networks. IEC 61850 not only provides a protocol for communication but is a whole new concept for naming and configuring substations and power grids.
The normative definition of logical nodes for DER is necessary for new smart grid appliances because process devices have to be described in such logical nodes for information exchange. Therefore it is important that current valid logical nodes in process protocols are not subject to change in the further standardisation process and to enable new devices to seamlessly comply with existing protocols without proprietary vendor solutions.”

Another key issue is the support of System interoperability operability testing!!

“A system interoperability testing method including conformance testing, "profiles" and "test use cases", should be provided by the end of 2013”

More to come – keep tuned to this blog.
