Instability Problems in Co-Simulation of Modular Systems
Paper in proceedings, 2020

To conduct virtual preparation and commissioning in an industrial setting, it is necessary to compose the simulation models using predefined models. However, there is a challenge to simulate such models, since often the structure and parameters of the models are hidden, due to protection of the intellectual property. This paper examines the possibilities and challenges of using co-simulations when such models are composed, and they do not share their internal parameters. These hidden parameters can affect the stability when simulating models connected through a weak coupling. This paper also proposes possible implementation methods for virtual commissioning, which circumvents these challenges with co-simulations.
