An Open-Source Industrial-Grade Collection of Renewable Energy Source Generic Models in Modelica Language

Abstract

In a context of massive penetration of Renewable EnergySources (RES) in the grid, it is of prime importance forTransmission System Operator (TSO) to correctly representthese components in their day-to-day dynamic simulationsused to assess system stability, both in operational andplanning situations. Well-parametrized genericPower Electronics Interfaced Resources (PEIR) models haveemerged as a viable option for TSOs for large-scalestability situations, and are largely available incommercial power system software. However, despite previousefforts in the open-source community, especially in theModelica one, there is a lack of a complete, up-to-date,and industrial-grade library. This paper presents thecurrent status of the Dynaωo Modelica library for standardPEIR models that tries to fill this gap. The library’sarchitecture and content, the implementation choices, andalready existing industrial usages of the models arepresented in detail, alongside validation cases and results.
