IEC systems committee Smart Energy (SyC SE) addresses standardization issues in the field of Smart Energy with the purpose of identifying systems level requirements for standardization, coordination and guidance in the areas of Smart Grid and Smart Energy, including interaction in the areas of Heat and Gas.

To achieve this goal, SyC SE determined that it was essential to consult widely within the IEC community and the broader stakeholder community to provide overall systems level value, support and guidance to technical committees (TCs) and other standards development groups, both inside and outside the IEC. From this consultation effort, SyC SE was able to select important cases that would benefit from standardization. After identifying and assessing the importance of these standardization cases, SyC SE has worked with the affected TCs to promote these efforts and periodically updates their progress in an SRD report (called the SyC SE development plan).

This document presents the current status of the SyC SE development plan for readers (not limited to IEC Smart Energy related members).

Since this content represents a snapshot of the dynamic/living standardization processes to be updated, it is subject to future change.

Main standardisation cases under focus


Standardization case objective summary


Increase profiling support:

Considering the increasing number of options in Smart Energy standards, and the increasing need for multi-vendor interoperability, IEC should encourage and support the profiling of usage of these standards (an agreed-upon subset and interpretation of a specification), Such an approach needs a complete framework to cover the full process from specification to testing, i.e. guidelines, processes, tools and hosting.


Connecting and managing DER standards:

Develop IEC product standards (IEC TC 82, TC 88, TC 95, etc.) permitting to demonstrate compliance with grid connection requirements.


Installations with multiple power sources:

To review installation rules for safety, especially with multi-sources aspect. IEC TC 64 should develop a dedicated part within the IEC 60364 series to cover this need together with IEC TC 8 for the Grid aspect of multisource installations.


Extensions to support dynamic system management:

Develop the needed extensions (data model and/or services) to support dynamic system management.


Guidance for IEC 61850 extensions:

In order to keep IEC 61850 overall consistency, and avoid potential overlaps, provide guidance to other TCs than IEC TC 57 on the process and technical rules to apply to make extensions to IEC 61850 in their own expertise domain. This applies to all potential application domains of IEC 61850 (i.e. is not substation automation system specific).


Promotion and expansion of IEC 61850-7-420:

Promote the use of IEC 61850-7-420 for all DER equipment and expand the standard to all kinds of possible equipment. This should be done in a generic way, which enables the inclusion of all kinds of DER equipment without explicitly describing single DER equipment. The current standard (IEC 61850-7-420:2009) is too detailed and therefore poses difficulties in achieving interoperability.


Cooperation of cross TCs for demand response applying to Smart Home and Building Automation Systems:

A close cooperation with the "demand response" activities is needed. Here use cases must be defined in order to specify the scope and involvement of the different stakeholders. For example, the contribution of HBES/BACS needs to be described in order to define their share in the overall systems (refer to S-AMI-4).


Standardization for interconnection and interoperability of large and distributed energy storage:

IEC TC 57 should develop an equivalent standard for connection of large and distributed storage systems. The result should be a generic description of the necessary data models, in order to accommodate the different requirements and possibilities of large and distributed energy storage.


Support for the long-term interoperability of IPv4 and IPv6:

Anticipate the use of IPv6, and ensure the availability of the concerned standards supporting IPv6.


Guidelines of smart energy cyber security requirements:

Given the complexity of business processes and the wide variety of cyber assets used in the smart energy environment, there is significant confusion about how to assess cyber security requirements and what cyber security standards are applicable. It is clear that no single cyber security standard can address all security requirements, security controls, resilience strategies, and technologies. Some existing standards and guidelines are focused on the high level organizational security requirements and the more detailed recommended controls (What), while other standards focus on the technologies that can be used to provide these cyber security controls (How). The main challenge is to clearly describe the issues around cyber security for smart energy operations, to provide guidelines for how best to use the existing cyber security standards, and what gaps might exist where new cyber security standards should be developed.


Extension of SGAM smart energy grid reference architecture

The SGAM framework is established by merging the concept of the interoperability layers with the smart grid plane. To describe the interaction between the electrical grid and the systems in the areas of Heat and Gas, SGAM extension will be needed.

Standardisation cases assessment

In producing this Development Plan, SyC SE is seeking to facilitate these standardization case activities by involving the relevant groups, and by monitoring and reporting on progress.

Basically, the development plan standardization cases fall into the following three scenarios :

  • Lead Group Scenario when the lead groups exist
  • Parallel Groups Scenario when coordination is needed across groups which are working in parallel
  • Hosted by SyC SE Scenario other than the two previous ones, in which the standardization case needs to be hosted by SyC SE

What will you find in the SRD 63199 ?

Each standardisation case is assessed in details and the SRD provides for each:

  • A summary of the purpose(s) of IEC effort
  • A description of current standardization efforts, triggered by the IEC Systsem Committee Smart Energy, across the whole IEC organisation
  • The description of remaining standardization efforts
