A toolbox for efficient parameter and structure variation of time domain power system simulation models in Simulink

Variation studies with Matlab/Simulink models are often limited to a handful of variation subjects due to the efforts involved. A toolbox for the efficient automation of parameter and structure variation of complex power system time domain simulation models in Matlab/Simulink has been designed and implemented. A requirement engineering process has been used to define necessary functionality. Several research use cases related to power systems have ensured the usage of best practices in the implementation. The toolbox proves to be beneficial for increasing efficiency in automated parameter and model structure variations and analyses of the results. The authors intend to make the source code and the documentation of the toolbox available for download under an open source license.
