Evaluation of Energy Transfer Efficiency for Shore-to-Ship Fast Charging Systems
Karimi, Siamak; Zadeh, Mehdi; Suul, Jon Are Wold (Peer reviewed; Journal article, 2020)Shore-to-ship charging systems are usually designed based on various operational and design parameters including the onboard power and propulsion requirements, available charging times, and the capability of local power ... -
Model-based efficiency and emissions evaluation of a marine hybrid power system with load profile
Ghimire, Pramod; Karimi, Siamak; Zadeh, Mehdi; Nagalingam, Krishna Kumar; Pedersen, Eilif (Peer reviewed; Journal article, 2022)In this paper, an efficiency and emissions evaluation framework for marine DC hybrid power systems is developed based on the physics- and data-based models of the power components. The proposed framework is tested under ... -
A Multi-Layer Framework for Reliability Assessment of Shore-to-Ship Fast Charging System Design
Karimi, Siamak; Zadeh, Mehdi; Suul, Jon Are Wold (Peer reviewed; Journal article, 2021)In this paper, a multi-layer framework is proposed to assess the reliability of Shore-to-Ship Charging (S2SC) systems, considering the potential for failures of the main elements, such as power converters and batteries. ... -
A multi‐layer framework for energy efficiency assessment of shore‐to‐ship fast charging systems including onshore batteries
Karimi, Siamak; Zadeh, Mehdi; Suul, Jon Are Wold (Peer reviewed; Journal article, 2022)This paper proposes a three-layer framework for energy efficiency evaluation of Shore-to-Ship Charging (S2SC) systems using load-dependent loss models of the components. The considered S2SC system is supplied by the grid ... -
Operation-based Reliability Assessment of Shore-to-Ship Charging Systems Including On-Shore Batteries
Karimi, Siamak; Zadeh, Mehdi; Suul, Jon Are Wold (Journal article; Peer reviewed, 2023)In this paper, an operation-based reliability assessment framework is proposed for Shore-to-Ship Charging (S2SC) systems including On-Shore Batteries (OSB). The OSB is considered to support the grid under fast charging ... -
Reliability Analysis of Shore-to-Ship Fast Charging Systems
Karimi, Siamak; Zadeh, Mehdi; Suul, Jon Are Wold; Thieme, Christoph Alexander (Chapter, 2021)This paper presents a reliability assessment of Shore-to-Ship Sharging (S2SC) systems with focus on the two most common topologies of ac and dc charging. In the proposed reliability model, the Markov chain and reliability ... -
