Open Challenges in Future Electric Ship Design: High-Frequency Disturbance Propagation in Integrated Power and Energy Systems on Ships

The power electronics converters increase power and number and thus lead to the injection of higher disturbances in a modem IPES. Moreover, the power distribution cables may have resonance frequencies that can be matched by high-frequency disturbances. Thus, specific system weaknesses can be identified through the development of a reliable modeling approach exploiting both frequency-dependent mathematical models and CSI software capabilities. The cable path and lengths must be accurately known to correctly assess the impact of high -frequency disturbance propagation in the IPES. In addition, the CSI approach permits accurate evaluation of the IPES parameters in early stage design, where any changes to the IPES layout do not lead to a considerable cost increase
