Various grid-following and grid-forming control concepts are being developed with the increasing integration of converters into the power system. To investigate the system stability and the interactions of such control concepts with bulk integration of renewables, a testbench has been developed including a MVDC/HVDC multi terminal system and various additional converter based sources and control schemes.
In this presentation, the process and challenges faced during the modelling of this testbench shall be discussed. This includes modelling the different equipment in the mainstep and substep, integrating different control concepts, the linkage to a transmission grid section and the resources needed. In addition, the model offers the opportunity to investigate the interactions of the modelled controls with real converters via Power Hardware-in-the-Loop. Finally, the runtime environment of the model with the startup scripts and the application possibilities of this testbench are discussed.
