What is PD IEC/TR 61850-90-8- Communication networks and systems for power utility automation about?
PD IEC/TR 61850-90-8 is a safety standard on communication networks and systems for power utility automation.
PD IEC/TR 61850-90-8 shows how IEC 61850-7-420 can be used to model the essential parts of the E-Mobility standards related to electric vehicles and electric vehicle supply equipment (IEC 62196, IEC 61851, IEC 15118) and the power system (IEC 61850-7-420), to secure an elevated level of safety and interoperability.
The namespace of PD IEC/TR 61850-90-8 is:
- “(TR) IEC 61850-90-8:2015”
The namespace "IEC 61850-90-8" is considered as "Transitional" since the model is expected to be included in the next edition of IEC 61850-7-420 1. Potential extensions/modifications may happen if/when the model is given International Standard status. The most optimal backward compatibility with the original content will be strived for during this move.
In accordance with the status of the ISO 15118 series and systems determined in IEC 61851-23 and -24, PD IEC/TR 61850-90-8 focuses on EV charging processes only.
Note: Discharging processes to support grid services are out of scope but will be adopted when available in future versions of ISO 15118-2 and IEC 61851-1, -23, and -24.
Who is PD IEC/TR 61850-90-8- Communication networks and systems for power utility automation for?
PD IEC/TR 61850-90-8 on object model for E-mobility is relevant to:
- Distribution system operators
- E-Mobility infrastructure producers
- E-Mobility infrastructure owners
- E-Mobility service providers
- Manufacturers of electric energy meters, electric vehicle
- Electricity providers
- Energy suppliers
Why should you use PD IEC/TR 61850-90-8- Communication networks and systems for power utility automation?
PD IEC/TR 61850-90-8, which is a technical report describes how current standardization for Electric Road Vehicles (EV) and the Vehicle-to-Grid Communication Interface can be linked to IEC 61850-7-420, which deals with Distributed Energy Resources (DER).
PD IEC/TR 61850-90-8 provides necessary background information and proposes an object model for E-Mobility to establish an EV plugged into the power grid as DER according to the principles of IEC 61850-7-420. The basic information modelling in IEC 61850 and IEC 61850-7-420 already covers a lot of needs for the E-Mobility domain. Missing parts can be modelled as new logical nodes and data objects, which PD IEC/TR 61850-90-8 defines.
Overall, PD IEC/TR 61850-90-8 is helpful as it assists the user with the E-Mobility domain considering the electric vehicle and the supplied equipment for delivering energy to the vehicle.
