Title

Engineering Recommendation (EREC) G5 Issue 5 (2019)

Harmonic voltage distortion and the connection of non-linear and resonant plant and equipment to transmission systems and distribution networks in the United Kingdom

Target Audience

The modifications will be of interest for persons who:

  • Propose to connect equipment with resonant plant to the public electricity supply system that has the potential for causing or modifying voltage harmonic distortion.
  • Propose to alter such a disturbing equipment/installation as mentioned above, connected to the public electricity supply system that would result in material changes in voltage distortion.
  • Carry out assessments of the connection of disturbing equipment and the resultant voltage distortion and issue harmonic limits.
  • Measure voltage distortion caused by disturbing equipment for the purpose of checking conformance with requirements in EREC G5.

Summary

This Distribution Code public consultation is seeking the views from industry stakeholders on the proposed modification to Engineering Recommendation G5, subsequently referred to as EREC G5 Issue 5.

This modification has been prepared under the authority of the Distribution Code Review Panel (DCRP) – EREC G5 being a Qualifying Standard and Licence Standard under the Distribution Code.

The DCRP establish and maintain governance arrangements for standards referenced in the Distribution Codes that have a material effect on Users of the Distribution Systems. As such, EREC G5 will approved by the Authority (Ofgem) before publication.

Since Engineering Recommendation G5 is referenced in the Grid Code, this Distribution Code Consultation is also being targetted at Grid Code users to collect feedback from the wider industry, however any change to the Grid Code to reference EREC G5/5 rather than EREC G5/4 will be considered separately under the Grid Code governance arrangements.

The proposed EREC G5 Issue 5 constitutes a full technical revision of Issue 4 published in 2005 and has been extended, amongst other things, to cover assessment for concurrent connections

Next Steps

Responses to this consultation should be sent to the Distribution Code Review Panel Secretary at dcode@energynetworks.org by 17:00 on 19 April 2019.

Stakeholder Dissemination Events

The DCRP mandated the EREC G5/5 Working Group to host two stakeholder dissemination events to explain the changes made to the ER G5/4-1 document to Users in advance of the public consultation closure on Friday 19 April 2019. The two dissemination events will be hosted in London on Monday 1 April 2019 and Glasgow on Wednesday 10 April 2019. Members of the EREC G5/5 Working Group will be in attendance to present to stakeholders.

The dissemination events will allow DCode stakeholders to ask questions about the revised EREC G5/5 document to assist in understanding the impact of the changes being proposed, and to provide the opportunity to clarify any of the consultation questions being asked.

To register for either two of the events, please see the following links:

Stakeholder event in London 1st April 10:00-16:00

Stakeholder event in Glasgow 10th April 09:30-16:00

A copy of the slides for the stakeholder dissemination event can be obtained here. The worked examples and calculation spreadsheet are also available.

Please note: Registration

Registrations to attend the London event will be limited to the first 50 attendees. Members who register after the invitation cap has reached will need to join the meeting remotely via webinar.

Webinar event in London 1st April 10:00-16:00

Registrations for the Glasgow event will be limited to 120 attendees but members will not be able to join by webinar.

*A recording of the webinar is planned and will be made available to the public.

DCRP/19/05/PC - DCode & G99 Mods for Fast Fault Current Injection

Title

Modifications to The Distribution Code and EREC G99 of the requirements for Fast Fault Current Injection

Target Audience

The modifications will be of importance to Distribution Code Stakeholders and Users including Distribution Network Operators and Generators, but particularly to manufacturers of Power Generating Modules.

Date Published

April 12 2019

Deadline for Responses

17:00 on 10 May 2019

Summary

This Distribution Code public consultation is seeking the views from industry stakeholders on proposed modifications to EREC G99 “Requirements for the connection of generation equipment in parallel with public distribution networks on or after 27 April 2019.

The proposed modifications are aimed at ensuring that the legal text for the fast fault current injection (FFCI) requirements in G99 is fit for purpose and provides an unambiguous description of what is required. The original legal text in G99 (and in the Grid Code) has been identified by stakeholders as problematic and this modification has been considered by a joint GCRP and DCRP working group to proposed amended text for both the Grid Code (proposed under GCode Modification GC0111) and G99.

Next Steps

Responses to this consultation should be sent to the Distribution Code Review Panel Secretary at dcode@energynetworks.org by 17:00 on 10 May 2019.
