In line with climate goals and ambitions, the maritime industry is undergoing a technological transformation. Hybrid vessels offer the opportunity to optimize the use of the available distributed (renewable) energy resources on the grid. Hybrid Vessel Energy Management Systems need to make decisions with objectives to reduce fuel consumption, greenhouse gas emissions and maintenance expenditures during operation of the vessel. The verification of the Energy Management System is conducted by creating a Digital Twin of the hybrid vessel on the Typhoon Hardware-In-Loop platform. The model results are achieved in real time, thereby setting the foundation for Controller HIL (C-HIL) projects.

With the maritime industry poised on the cusp of a hybrid revolution, the design and analysis of advanced vessel systems have become paramount for engineers. This paper presents AC and DC electrical hybrid power system models in ETAP, the simulation software that can be adapted to engineer future hybrid vessels. These models are also a step towards a digital twin model that can help in troubleshooting and preventing issues, reducing risk and engineering time. The testing of the models is focused on time domain analysis, short-circuit currents, and protection & coordination. The models are based on actual vessels and manufacturer parameters are used where available.
