Software Specifications

RMT Specification

This document is the functional specification for the System Operator’s Reserve Management Tool (RMT). This application software is used by the System Operator to calculate the instantaneous reserves required to meet the Reserve Management Objective.

Link/Version Date Short Description of Changes
RMT Specification (version 4.0 [ pdf 742.49 KB ]) 20 Oct 2016 Update associated with implementing National Market for Instantaneous Reserves and risk groups.
Draft RMT Specification (version 4.0)  [ pdf 746.65 KB ] Draft

This version includes changes to incorporate the National Market for Instantaneous Reserves (NMIR). The general description of the New Zealand electricity system has been updated along with the South Island AUFLS modelling parameters.  

RMT Specification (Version 3.0) [ pdf 454.75 KB ] 17 Oct 2014 Major update resulting from the change of the RMT software application from Simulink to RMTSAT.

SPD Formulation 

This document is a mathematical description of Transpower’s “Scheduling, Pricing, and Dispatch” (SPD) software to be used by the New Zealand Electricity Market. 

Link/Version Date Short Description of Changes
SPD Formulation (version 11.1) [ pdf 986.52 KB ] 22 Nov 2016 Minor change to section 5.4 to reflect changes to shared reserve loss modelling during DC outages.
Draft SPD Formulation (version 11.1) [ pdf 988.53 KB ] Draft Minor change to section 5.4 to reflect changes to shared reserve loss modelling during DC outages.
SPD Formulation (version 11.0) [ pdf 985.32 KB ] 20 Oct 2016

Update associated with implementing National Market for Instantaneous Reserves and risk groups.

Note that the shared reserve loss calculation uses the bi-pole loss tranch value when a pole is out of service. This has no impact on security. This will be changed in the next SPD release to calculate based on the relevant mono-pole loss tranch value.

Draft SPD Formulation (version 11.0) [ pdf 1007.61 KB ] Draft

This version incorporates changes to allow SPD to schedule shared reserve across the DC link to facilitate the transition from Island based reserve markets to a national reserves market. It also includes changes to allow SPD to co-optimise risks defined as all units at a Grid Injection Point (GIP) or multiple GIPs.

Note that the shared reserve loss calculation uses the bi-pole loss tranch value when a pole is out of service. This has no impact on security. This will be changed in the next SPD release to calculate based on the relevant mono-pole loss tranch value.

SPD Formulation (version 10.0) [ pdf 774.27 KB ] 01 Apr 2016 Update associated mainly with correction of reserve price definition and generation ramp model.
