Muthumuni Introduction • Investigate if a software package originally developed for studying continental grids can be seen as COTS implement for ship power quality case studies (professional and educational purposes). • However, • theoretical argumentation the soft-program (not equipment) is used for the simulation of representative power quality phenomena occurring in ship electric power systems, • where necessary the effect of certain critical parameters is investigated, too. • On this occasion, as the case studies especially in warships with extended electrification (AES) involve problems emerging from the integration of modern devices without authenticated circuit modeling, novel circuit models proposed or improved by the authors are presented and validated. 3
