Nordic44 - 2015 Powerflow Data: An Open Data Repository of an Equivalent Nordic Grid Model Matched to Historical Electricity Market Data for 2015

This repository is used to provide documentation related to the model and data development process, provide source (raw) data for the model in different forms (i.e. Modelica, CIM 14, and PSS/E) for an equivalent Nordic grid model that has been matched to historical power flow data.

The repository is documented in the paper below, see [Ref00].

Using this model, data or related software = cite our publications!

We are happy to contribute with this dataset, however, if you use any of the data or software provided, we will appreciate if you cite the following publications, as follows:

A) Cite that "the raw and processed data files corresponding to the model are available as an open data set and documented in [Ref00]."

B) Cite that the first appearance of the model, i.e. "the model is first presented in [Ref01]"

Acknowledgment:

This model was originally developed in the context of the FP7 iTesla project, and further extended within the ITEA3 openCPSproject.

Structure of the repository:

01_PSSE_Resources:

1. Models :

   • A folder with PSS/E files of the base case

   • A folder with a 7zip archive containing files of the original N44 system that has been modified to have the PSS/E base case

2. Snapshots :

   • N44_2015xxxx are folders named according to the day they refer to (for example N44_20150401 refers to the 1st of April 2015). In each folder there are Excel files (Consumption_xx.xlsx, Exchange_xx.xlsx, Production_xx.xlsx) with data downloaded from Nord Pool website, an Excel file (PSSE_in_out.xlsx) summarizing the results from the Python script Nordic44.py in the folder 04_Python_Resources, PSS/E snapshots for each hour before solving the power flow (hx_before_PF.raw) and after solving the power flow (hx_after_PF.raw)

   • N44_BC.sav is the PSS/E solved base case that Python script Nordic44.py (put the reference)

02_CIM14_Snapshots:

• N44_2015xxxx are folders named according to the day they refer to (e.g. N44_20150401 refers to the 1st of April 2015). In each folder there are CIM files for each hour (N44_hx_EQ.xml, N44_hx_SV.xml_, _N44_hx_TP.xml)

• N44_noOL_RDFIDMAP.xml is the file with IDs mapping of those cases (N44_hx_noOL_EQ.xml, N44_hx_noOL_SV.xml, N44_hx_noOL_TP.xml) with fixed overloading problems.

• N44_RDFIDMAP_2015-1.xml and N44_RDFIDMAP_2015-2.xml are the files with IDs mapping of the remaining snapshots from 2015

03_Modelica:

1. iTesla_Platform

   • iPSL folder contains the version of the library which can be used to simulate snapshots generated from the iTesla Platform

   • Modelica_snapshots Modelica models generated from the snapshots by iTesla Platform

2. SmarTSLab

   • OpenIPSL folder contains the version of the forked iPSL library which can be used to simulate the manually generated Modelica model of N44 with the record structures corresponding to the snapshots

   • Snapshots folder contains Modelica records automatically generated from the PSS/E records

   • N44_Base_Case.mo is the handmade N44 model with the loaded record of the power flow results from the PSS/E base case. It can be used to load other PF results from the folder 03_Modelica/Snapshots
