Testing models and physical C&P replicas prior to interaction studies in a MV and MT context

To address this, the InterOPERA project has defined the minimum requirements applicable to the models and replicas provided by vendors [1], enhancing tool independence and facilitating their integration on multiple platforms. Then, as part of the InterOPERA project, seven participating vendors provided template models and replicas based on those requirements.

Concurrently, to guarantee the replicability of the proposed process beyond specific implementation choices, two laboratories (TU Delft and RTE) prepared their simulation platform based on [2] and tested the integration of the models and replicas in multiple offline and real-time simulation environments.

This paper presents the lessons learned from these tests by evaluating the success of the

InterOPERA requirements and methodology. Besides, it aims to identify areas for further development, recommendations, and refinement to ensure the smooth integration of all models and replicas.

Among the key findings for the offline models, the vendors achieved the provision of control and protection Dynamic Link Libraries (DLLs) for converter stations, wind turbine controllers, power plant controllers, DC switching stations and DC grid controllers based on [3]. The laboratories successfully integrated these models into two EMT tools without any numerical conflicts, providing the chance for conducting the first MTMV interaction tests.

Regarding real-time replicas, although interface documentation requires significant effort from vendors, it has proven instrumental in successfully integrating their solution into two different real-time environments as a single-vendor. Furthermore, the laboratories are facing challenges in moving to multi-vendor simulations due to time step constraints. Therefore, further work on this topic is recommended to address this challenge more effectively in future projects.
