PD IEC/TR 62357-1:2016

What is PD IEC/TR 62357-1- Power systems management and associated information exchange- Reference architecture about? 

PD IEC/TR 62357-1 is a safety standard on power systems management and associated information exchange. 

Electricity grids from generation to consumers, including transmission and distribution, as well as energy markets are facing many new challenges while integrating an increasing variety of digital computing and communication technologies, electrical architectures, associated processes, and services. The new challenges lead very often to support an increasing level of interaction between involved actors, components, and systems. 

Thus, it is key for the IEC to propose a clear and comprehensive map of all standards which are contributing to support these interactions, in an open and interoperable way. 

The purpose of PD IEC/TR 62357-1 is to provide such a map (as available in 2016), but also to bring the vision of the path which will be followed by the concerned IEC technical committees and working groups in the coming years, to improve the global efficiency, market relevancy and coverage of this series of standards. 

Who is PD IEC/TR 62357-1- Power systems management and associated information exchange- Reference architecture for?  

PD IEC/TR 62357-1 on reference architecture is relevant to: 

• Information and communication technology (ICT) providers 
• Security managers 
• Testing and maintenance personnel 
• Utility regulators 
• Project managers 
• Enterprise architects 
• Distribution System Operators and Grid Operators 

Why should you use PD IEC/TR 62357-1- Power systems management and associated information exchange- Reference architecture? 

A Reference Architecture describes the structure of a system with its element types and their structures, as well as their interaction types, among each other and with their environment. 

Describing this, a Reference Architecture defines restrictions for an instantiation (concrete architecture).  Reference Architecture facilitates the conceptual model of Smart Grids Use Case (UC and requirements enabling the different UC to be implemented and describing links between, Grid, 

Markets and Grid Users domain. Both the conceptual model and the Reference Architecture plan to use the same methodology and the same definition of actors and roles. PD IEC/TR 62357-1 provides high-level assumptions about how systems should interoperate. 

The main purposes of PD IEC/TR 62357-1 are: 

• To guide designers of standards for data exchange, by clarifying the purpose of data exchanges between systems, applications, components 
• To guide application designers by clarifying what the overall vision expects from their systems 
• To guide utilities in establishing implementation architecture that will accomplish their tasks effectively 

The role of the Reference Architecture is to support and assist standardization groups and to provide them with easily applicable methods and architectures and ensure an easy understanding of the approach. 

Overall, PD IEC/TR 62357-1 is beneficial as it helps users as a guide to workable standards, useful to delivering the best value by ensuring that technical investments by energy providers utilize standards wisely and introduce to standards related to Smart Grids privacy and security. 

What’s changed since the last update? 

PD IEC/TR 62357-1:2016 replaces the first edition published in 2012 and constitutes a technical revision. 

PD IEC/TR 62357-1:2016 includes the following significant technical changes with respect to the previous edition: 

• PD IEC/TR 62357-1:2016 provides updates and defines layered Reference Architecture to help direct longer-term goals and activities, specifically to ensure compatibility of all new standards developed in the IEC by benefitting from lessons learned during the development of the current standards and their application to actual utility projects as well as through the application of other internationally recognized architecture standards 
• PD IEC/TR 62357-1:2016 reflects the progress recently achieved with the international Smart Grids (SG) initiatives and the CIGRE D2.24 large system architecture vision. It also leverages the work done by NIST-SGIP, CEN-CELELEC-ETSI SGC G M490, IEC SG3 Smart Grids Roadmap, and IEC SyC Smart Energy working groups 

PD IEC/TR 62357-1:2016 also reflects the most recent editions of the IEC standards relating to power systems management and associated information exchange, including the IEC 61850 series and the IEC 61968, IEC 61970, and IEC 62325 Common Information Model (CIM) standards.
