Co-simulation Between Trnsys and Simulink Based on Typel55

摘要

The interface between Trnsys and Matlab based on Typel55 of Trnsys' standard library is used to construct a co-simulation between Trnsys and Simulink. The high flexibility of this interface is demonstrated, which includes its ability to provide a communication in strong and loose coupling schemes. A simplified use case including a compact thermal energy storage is considered to discuss accuracy and computational demands for various settings of the co-simulation. Loose coupling with constant and linear extrapolation of the input variables is presented, as well as an application of the strong coupling scheme to estimate the inaccuracies of the loose coupling co-simulation.
