6 FAQs about [Onboard energy storage circuit]

Can onboard energy storage devices reduce the catenary energy consumption?

Abstract: For improving the energy efficiency of railway systems, onboard energy storage devices (OESDs) have been applied to assist the traction and recover the regenerative energy. This article aims to address the optimal sizing problem of OESDs to minimize the catenary energy consumption for practical train operations.

Can energy storage be integrated into on-board power systems?

While there is some overlap, the maritime industry poses specific challenges to the successful integration of energy storage into on-board power systems: size and weight are of greater importance, the power system is isolated for most of the time and the load characteristic of propellers favours mechanical propulsion.

How does on-board energy storage affect a ship's energy management strategy?

The exact effect of on-board energy storage depends on the ship functions, the configuration of the on-board power system and the energy management strategy. Previous research in this area consists of detailed modelling, design, and comparisons of specific on-board power systems for explicitly defined operational profiles.

Should energy storage be used on-board ships?

Conclusions Several general observations on the use of energy storage on-board ships can be made from the presented results: 1. Systems with electric transmission benefit more from the use of energy storage than systems with hybrid transmission, as there are less losses associated to the battery.

Can onboard batteries save energy?

A relevant number of urban and regional rail vehicles with onboard batteries are in operation in Europe, America, and Asia at this time. Practical use of such storage devices has shown that energy savings, line voltage stabilization, and catenary-free operation can be effectively achieved .

How efficient is energy storage in a ship?

The relative efficiency of using batteries varies between -48% and + 57%. Energy storage has the potential to reduce the fuel consumption of ships by loading the engine (s) more efficiently. The exact effect of on-board energy storage depends on the ship functions, the configuration of the on-board power system and the energy management strategy.
