“…5 [30]. In addition to that, the dual-active bridge (DAB) topology is seen to be a good candidate when higher boosting ratios are mandatory [31]- [35]. On the other hand, the load AC/AC PCSs are commonly implemented using the back-to-back two-level VSI configuration, which is shown in Fig.…”

Transportation electrification is undergoing a significant transitioning towards the utilization of efficient and reliable energy sources and smart integration schemes, where this transitioning is continuously facing ever-tightening challenges in order to comply with the increased environmental regulations. Among the different means of transportation, the global maritime transport is responsible for 2-3% of global greenhouse gas (GHG) emissions and it is predicted to increase to 17% by 2050 if no changes are adapted. Hence, the international maritime organization (IMO) has targeted to reach a 50% reduction in GHG emissions by 2050 compared to 2008. Hence, alternative energy sources shall be utilized in order to meet these strict GHG emissions reduction targets, where batteries and hydrogen-fed fuel cells can play a vital role in such aspect. Since the output of these two energy sources is unregulated DC voltage, their connection to the whole ship power system can be accomplished in several ways, where each way has its features, in addition to utilizing different power conditioning stages (PCSs), and these features are not well clarified and compared in the literature. Hence, this paper presents an overview of the possible integration schemes that can be utilized in fuel cells and batteries-fed vessels, which is supported with a comparative assessment. This is also presented along with highlighting the state-of-the-art PCSs that are available in the market and can be utilized in these integration schemes within marine vessels. Such overview and comparative assessment are seen to be of significant importance and added value for researchers and developers in both the academic and industrial sides in order to accelerate the adoption of fuel cells in marine systems for zero emission shipping.

“…It provides the six-step AC voltage waveform across the centred transformer windings. The six steps mode leads to achieving the zero-voltage turn ON in case of inductive loads and the connected snubber capacitors among power electronic devices can result in a significant reduction in turn OFF loss [17], [20], [28]. The power is transferred as a result of phase-shifted voltages [17], [29].…”

MVDC technology is a promising solution to avoid installation of new AC networks. MVDC can provide optimum integration of large-scale renewable energy sources, the interconnection of different voltage levels of DC and AC grids with the ancillary services. The development in MVDC depends significantly on the DC-DC converters. Such converters support the modern trends of utilising medium-frequency transformers in power networks. Research on isolated converters technology is in its infancy and limited by the conversion ratio and component ratings. Besides, there is no standards exist covering specific aspects of isolated converter product. Thus, a review of such converters is needed. This work presents, for the first time, a review of the DC-DC power converter families in MVDC grids including the leading families which are isolated and nonisolated converters, as well as other subfamilies comparing the specifications and characteristics. Also, the applications of these converters are provided by focusing on the essential requirements for each application. Index Terms-MVDC grids, DC-DC power converters, dual active bridge (DAB), multilevel converter.

“…In [16]- [18], the improved MPC based EMS is adopted to handle the power in HESS to compensate the pulse load, but the SOC of the ESDs still need to be optimized. In [19], the master-slave based EMS is introduced to allocate the power between different converters to compensate the pulse load. In [20] and [21], the fuzzy logic based EMS are studied and the reference power is obtained according to the voltage fluctuation and SOC of the ESDs, and then allocated through a low-pass filter (LPF).These centralized EMS can allocate the demanded power in HESS fast and accurately, but the size and lifetime of the HESS which is critical to the IPS still need to be optimized.…”

Hybrid energy storage system (HESS) consisted of battery and supercapacitor plays an essential role in supporting the normal operation of pulse load in vessel integrated power system (IPS) as well as improving power quality. However, due to the unique properties of the pulse load and diversified operations of the vessel, such advanced power system architectures tend to face greater challenges in optimal power allocation. In order to address the power allocation challenges, a novel optimized state-of-charge (SOC) feedback based energy management strategy is proposed for HESS in IPS to restrain the DC bus voltage fluctuation in this paper. Firstly, considering the operating characteristics of the pulse load in IPS, the optimized SOC of the HESS is introduced to the low-pass filter (LPF) with variable time constant to split the power in the HESS. Secondly, SOC recovery control of the supercapacitor is introduced to the LPF to optimize the size of the HESS as well as prolong the lifetime of the battery. Also, the enforced intervention is introduced to avoid the opposite state of the HESS. The proposed strategy can make full use of the HESS complementary characteristics to compensate the pulse load and optimize the HESS. Finally, the simulation conducted in PSCAD demonstrates the effectiveness of the strategy proposed in pulse load compensation as well as HESS optimization. INDEX TERMS Integrated power system, pulse load, hybrid energy storage system, low pass filter, SOC recovery, SOC feedback.
