ScalableTestGrids - A library of power system large-scale test cases to assess Modelica tools performance
This repository contains the code for ScalableTestGrids, a Modelica library created to generate power system large-scale test cases to assess Modelica tools performance. This library was originally developed by RTE with help from Dynamica s.r.l. It is part of a larger effort to promote both the use of Modelica for power system modelling and the advantages of open-source approaches (for more detail, go to Dynaωo website).
The ScalableTestGrids is a library of power system large-scale test cases to assess Modelica tools performances. It is based on the PowerGrids models and represents an excellent, high-quality and publicly available benchmark to test the efficiency of Modelica tools on large-scale problems and the progresses done on this topic.
The library offers the possibility to easily create new test cases by setting two integer scaling factors N and M. Each test system is a 2N x 2N EHV (400 kV) grid, with alternating generator and load nodes. Each generator node is fed by a controlled synchronous generator, taken straight from the PowerGrids library examples in the tutorial, and by a step-up transformer. Each load node is connected to a step-down transformer to 63 kV, which is followed by M series-connected HV lines, with a PQ load attached at the end of each one. The systems start in steady state, then at time = 1 the loads of the upper half of the grid are reduced by 10% - this triggers a transient involving the primary frequency control, and also a bit of inter-area oscillations, since there is some power transfer from south to north at the beginning.
