Background

Two issue papers as:

Reactive & Frequency Response Fax Forms previously discussed at EBSG in 2011 & 2012 Parameters & instructions one is more complex One market participant asked if we could introduce the reactive fax form changes more quickly Ambiguity in existing reactive forms has caused some issues

Balancing Code Parameters

Time-varying SEL/SIL (in 2nd EBS consultation) Run-Up and Run-Down Rates (in 2nd EBS consultation): Maximum of ten ramps, rather than three at present Minimum ramp rate reduced from 0.2MW/min to 0.02MW/min Remove the requirement for Generators to submit Dynamic Parameters (Day Ahead) as data is no longer used Address the defect that the Grid Code does not detail the arrangements that apply when re-commencing generation following instruction from National Grid to shutdown e.g. NDZ

  • nly applies when the PN is zero

Accounts for a significant portion of all re-scheduling activity

Balancing Code Instructions

Reactive instructions Of the form:

For immediate actions or at some future time Can be sent to one unit, or more than one unit Types of target MVAr, target voltage, or tap

As the industry have requested, moves simultaneous tap instructions away from faxes Target Frequency Change Moves it from telephone, faxes or call broadcast system To Automatic Logging Devices which receive all other instructions

Reactive & Response Fax Forms

We acknowledge that using faxes is outdated Main reason for discussing fax formats is to determine data to be exchanged by EBS new industry interfaces Have looked to simplify data exchanged And remove ambiguity

Recommendations

For both issues, GCRP is invited to:

Recommend that the Electricity Balancing System Working Group progress these issues to Industry Consultation
