Principle of Shipborne New Energy Storage System

By studying the structure and principals involved in new energy-based ship power systems, the composition of new energy-based ships and the basic criteria shaping their application can be better understood.

Energy storage systems are critical components of shipboard microgrids, which provide reliable and efficient power to SMG. As the demand for sustainable and green energy solutions continues to increase, the field of energy storage is rapidly evolving to meet the needs of the marine industry.

This study focusses on the energy management of hybrid energy storage system sizing in shipboard applications, which aims to meet the fluctuating propulsion loads.

In this article, a novel hybrid energy storage system based on battery and pulsed alternator is proposed. The topology principle of the system, the design scheme of the pulsed alternator, and the cosimulation results of multimodules are described in detail.

In the all-electric ships (AESs), the uncertain navigation conditions bring the drastic propulsion power fluctuations and the uncertain power control characteristics of large-scale shipboard hybrid energy storage systems (HESSs). A dynamic power management method of shipboard HESS is therefore proposed in this article.

4 FAQs about [Principle of Shipborne New Energy Storage System]

What is a decentralized Coordination Strategy for a shipboard hybrid energy storage system?

The proposed decentralized coordination strategy for the shipboard hybrid energy storage system does not require a link with other system components, unlike a conventional strategy. To ensure power sharing in the ship power system, the initial SOCs for the batteries are 70% and 25%, and the supercapacitor is 50%.

Can hybrid energy storage systems reduce the environmental impact of ship operations?

Recent research has demonstrated the significance of employing energy management systems and hybrid energy storage systems as effective approaches to mitigate the environmental impact of ship operations. Thus, further research could be carried out to explore how hybrid ESS can be optimized in terms of their size, lifetime and cost.

What type of storage principle should a ship use?

That may define the type of storage principle to select: sensible or latent heat, or thermochemical. Obviously, in a ship the objective is to minimize the system size.

Can thermal energy storage be used on ships?

Implementation of thermal energy storage on ships Thermal energy storage technologies have been applied in many other fields, where balancing of mismatch between energy production and demand is required.
