ReliCapGrid Test Model

ICTC approved on 11 September 2025 — actively improved and enhanced throughout 2026.

Introduction

This repository contains a synthetic grid model (fake, with no reference to real IGM/CGM elements)​ that instances of the ENTSO-E CIM extension called "Network Code Profiles" refer to.

Note: This document uses several technical abbreviations (e.g., TSO, IGM, CGM, CSA). For full definitions, please refer to the Glossary of Abbreviations at the end of this README.

The aim is to demonstrate practical TSO and RCC data exchange use cases for the Regional Coordination Processes, namely the Coordinated Security Analysis (CSA), Coordinated Capacity Calculation (CCC), Outage Planning Coordination (OPC) and the Short-Term Adequacy (STA).

The Regional Coordination Processes Data Exchange Specification (RCP DES) complements the test model as this is the document describing use cases and general guidance on the use of Network Code Profiles. Find this data exchange specification and more on the ENTSO-E's CGMES Library.

ENTSO-E continuously collaborates with an ecosystem of TSOs, RCCs, regional projects and relevant industry software vendors. One of the outputs of this collaboration is the ReliCapGrid test model. Readers can consult the Accreditations section down below to see the list of people and organisations collaborating under the CC-BY-SA-4.0 open-source License.

The following chapters describe the model content, which will be continuously improved in subsequent releases.

It must be mentioned that the synthetic grid model Svedala is based on Svenska Kraftnät's test model of the same name, which is licensed under CC BY-SA 4-0 open-source license.


How to Assemble File Packages for Import

Each TSO's grid model files are organized under Instance/TSO/Grid folders, serialized in multiple forms, with CIMXML being the primary serialization under active development. Similarly, the test Network Code Profiles instance datasets can be found under Instance/TSO/NetworkCode. The following guidance describes which files to combine when creating import packages for your tooling.

Individual Grid Model import with individual boundary files - IGM

  • All profiles from the respective Instance/<TSO>/Grid/cimxml folder (EQ, SSH, SV, TP)

  • The relevant per-border boundary file(s) from Instance/boundaryData/Grid/cimxml

  • All CommonData for Grids files from Instance/commonData/Grid/cimxml

    additionally the Network Code Profiles:

  • Desired profiles from the respective Instance/<TSO>/NetworkCode/cimxml folder

  • All CommonData for Network Code files from Instance/commonData/NetworkCode/cimxml

Common Grid Model creation - CGM

  • The EQ profile from each Instance/<TSO>/Grid/cimxml folder

  • All files from Instance/Jotunheim/Grid/cimxml (SSH, TP, SV)

  • All relevant per-border boundary file(s) from Instance/boundaryData/Grid/cimxml

  • All CommonData for Grids files from Instance/commonData/Grid/cimxml

    additionally the Network Code Profiles:

  • Desired profiles from the respective Instance/<TSO>/NetworkCode/cimxml folder

  • All CommonData for Network Code files from Instance/commonData/NetworkCode/cimxml

The load flow calculation parameters are documented in the power flow settings document.

The sematic-tools folder includes some scripts to convert CIMXML to Trig (Turtle with named graphs) and fix some instance data problems, and it describes the location of Trig files and how to zip them up together with all manifest.ttl files, for direct loading to a semantic graph database.


The Grid Test Model

ReliCapGrid consists of the following fictitious TSOs, as shown in Figure 1 below:

  • Espheim - developed based on legacy SmallGrid Test Configuration
  • Svedala - developed based on Svenska Kraftnät's Svedala Test Configuration
  • Belgovia - developed based on legacy MicroGrid Test Configuration
  • Galia - developed based on legacy MicroGrid Test Configuration
  • Nordheim - only one node
  • Britheim - includes HVDC internal interconnection VSC and also some small grid 1-2 nodes
  • Portheim - few nodes modelled in a boundary substation
  • HVDC Espheim-Svedala - an HVDC IGM LCC
  • HVDC Nordheim-Galia - an HVDC IGM VSC Bipole

All of them are in a geographical region called Nine Realms. This information and more - like the voltage level of the transmission network - is available in the synthetic Common Data dataset that has been created for ReliCapGrid. As the name suggests, it is designed to replicate the real (public), more extensive ENTSO-E Common Data dataset available on the CGMES Library.

A detailed boundary description is available in the docs folder.

The Network Code Instances

The Nine Realms region that ReliCapGrid represents also happens to be a capacity calculation region called CCR-NineRealms that has a few synchronous areas, with SyncArea-Continental being the main one.

The SecurityCoordinator and CoordinatedCapacityCalculator roles are represented by Jotunheim, which is analogous to a Regional Coordination Centre (RCC) in the real world.

This information and more (e.g., BiddingZoneBorder) is again represented in the Common Data dataset that the Network Code Profiles instances use. A synthetic common data dataset for the Network Code Profiles has been created and follows the roles defined in the PowerSystemOrganizationRole diagram of the EquipmentReliability profile (refer to Figure 2).

Currently demonstrated Network Code Profiles instances

Currently, four of the TSOs in NineRealms (Belgovia, Galia, Svedala and Espheim) have provided their Network Code Profile instances for Jotunheim to use in coordination.

Namely, the AssessedElement (AE), Contingency (CO), EquipmentReliability (ER), RemedialAction (RA), RemedialActionSchedule (RAS), StateInstructionSchedule (SIS), SteadyStateInstruction (SSI) and ImpactAssessmentMatrix (IAM) are demonstrated in the ReliCapGrid repository.

As already mentioned, ENTSO-E explains the use of the Network Code Profiles in the Regional Coordination Processes Data Exchange Specification.

The ReliCapGrid Network Code Profile instance data will be further developed and demonstrated in subsequent releases.
