Power system and energy storage models for laser integration on naval platforms

Abstract

This paper reports on the progress of detailed MatLab/Simulink models of a destroyer class ship service electric power distribution system that have been developed to evaluate the performance of battery, flywheel, and capacitor energy storage in support of laser weapons. The models allow the user to develop comparative studies of the three energy storage systems in regard to several relevant metrics that can be used for their discrimination. Examples of some of these results based on the simulations are given.

Assessing battery energy storage for integration with hybrid propulsion and high energy weapons

“…Battery based pulsed power is not in itself a novel concept, Huhman et al (2016) describe the design of a battery system used to charge a capacitive device capable of delivering 12 kJ/s at 10 cycles per minute for a 5 minute, 50 shot salvo. Gattozzi et al (2015) investigated the ability of a Li-ion Energy Storage System (ESS) to power sub 125 kW LDEW loads, however little discussion was offered on the Li-ion battery model fidelity. This investigation differs for two reasons, firstly the battery system is the sole source for the pulsed load as opposed to a battery/capacitor combination for electromagnetic launch purposes as researched by Huhman et al (2016).…”

Investigating the Performance Capability of a Lithium-ion Battery System When Powering Future Pulsed Loads

“…Future warships are predicted to employ advanced weapon systems, the power for which will be drawn from the ships electric power system. Key among these advanced systems are high power laser directed energy weapons (LDEWs) characterized by a pulsed power profile [1][2][3][4]. Pulsed power load supply is an important factor driving change in power system design and is considered a primary requirement for the integration of energy storage devices that have fast response dynamics capable of driving pulsed loads for sustained periods [5].…”

“…At present, lower power LDEWs below 100 kW are being tested onboard warship power systems [6]. However, the peak pulse power requirement of LDEW systems is currently expected to be up to 2 MW [1][2][3]7].…”

“…A review of the literature highlighted a gap in the understanding of the capability of batteries when used in pulse power applications. Publications on batteries used to power pulsed loads are few [2,10,11] and includes the authors' own publications [12,13]. Simulation-based work in [2] has demonstrated that lithium iron phosphate (LFP)-based li-ion batteries could be capable of providing for such loads.…”

Simulation-based work in [2] has demonstrated that lithium iron phosphate (LFP)-based li-ion batteries could be capable of providing for such loads. However, the li-ion battery model, power electronic interface and control system in [2] were not presented in sufficient detail to conclude the battery performance limitations under LDEW operation.…”
