This webinar introduces the IEC61850 standard on communication protocols for intelligent electronic devices at electrical substations, and its benefits. The interoperability needs and issues are presented, as well as the IEC61850 scope and structure, its applications fields, and complementarity with other standards. It concludes on the ongoing developments within the OSMOSE project for the standard’s implementation (subject of a second webinar). Key messages The IEC61850 is an international standard defining rules and guidelines for substation protection and automation system communication, configuration and testing, supported by a data model and a configuration language. The IEC61850 standard provides an engineering process to allow efficient device configuration. Osmose provides and demonstrates the required extensions for engineering process extensions to support an efficient top-down end-to-end engineering process from concept and specification to configuration. Osmose provides recommendations for IEC61850 WG10 in order to integrate the projects developments into a future release of the standard.

27. Requirements for DER modeling
Distributed Energy Resources in the power system
• DER includes generation, controllable loads and energy storage
• Utilities are responsible for reliability and electrical requirements within the distribution system
• Large amounts of DER connected to the distribution grid need to be handled
• Utilities need information about location, capabilities and operational status of the DERs
• DERs may have to comply to grid codes
• DERs can assist in meeting utility requirements
INTRODUCTION TO IEC61850
03/05/2021 27

28. Requirements for DER modeling
Stakeholders exchanging information with DERs
• DER controller
• Autonomous operation of DER
• Facility DER Management
• Management of multiple DERs at a facility
• Third parties
• Aggregators manage multiple DERs at distributed locations
• They can manage single DERs directly or multiple DERs through a facility management system
• Utility operational grid management
• Utility applications may require interaction with DER both monitoring as well as control
 To enable the access of those different stakeholders to a DER, a standardized semantic data model
significantly reduces integration effort
INTRODUCTION TO IEC61850
03/05/2021 28

29. Requirements for DER modeling
Examples of information exchange with DER
• Nameplate like capabilities or ratings
• Operational settings like parameters for grid code functions
• Real time data like real power output
• Activation of operational functions like volt-var control
• Send schedules like active power schedule for next day

30. Elements of a DER Model in IEC 61850
Recursive hierarchy
• DER model is recursive – a DER is
composed of DERs
• A DER unit is of a single type –
generation, storage or load
• A composed DER is of type mixed

• Capabilities (ratings)
• Settings
• Status
• Can be
• Generator DGEN

Logical Device

35. Elements of a DER Model in IEC 61850
Storage DER
• Generic characteristics of storage as
Generator and Load are expressed with
DGEN / DLOD
• Specifics of the DER unit (battery) is
expressed with DBAT
INTRODUCTION TO IEC61850
03/05/2021 35

36. DER modeling in IEC 61850 – Summary
• The modeling approach for DERs in IEC 61850-7-420 provides
• A standardized generic view of a DER independent of the DER type as it may be needed for operational
management of the DER by various stakeholders like aggregators or utility operational grid management
• Type specific information as it may be needed for maintenance
• The possibility to model aggregated DERs as a single DER with the same standardized generic view
• Additionally, IEC 61850-7-420 provides models for operational functions like Grid Codes supporting
a standardized access to parameters
• For integration of devices with legacy interfaces like Modbus or IEC 60870-5-104, IEC 61850
defines mappings which allows to link information elements from the legacy protocol to the semantic
IEC 61850 data model
