Challenges and needs for high power combined charging of ferries and electric vehicles - a Norwegian case study

Electrification of car and passenger ferries is an important step towards maritime decarbonization. Charging profiles are generated using a probabilistic method for electric vehicles (EVs) and a deterministic method for electric ferries. A test scenario from western Norway is taken for analysis with 2 MW and 9 MW ferry charging together with high power EV charging. The ferry charging causes an increase in peak load which could be mitigated by installing a battery energy storage system (BESS). When high power EV charging is included in the two cases, the peak demands increase even more. Without a BESS, reinforcing the power grid would be required.
