“…Us Navy is trying to pull out from a stage dominated with hydraulic, pneumatic, and mechanical-based devices to a stage governed by electromechanical-based devices and with full electric control [56]. Future naval electric weapons require higher power pulses of electrical energy [57]. It is predicted that 200 MJ pulse forming network is necessary for the Navy's railgun to attain the anticipated muzzle energy of 63 MJ 2 [58].…”

In recent years, concerns about severe environmental pollution and fossil fuel consumption has grabbed attention in the transportation industry, particularly in marine vessels. Another key challenge in ships is the fluctuations caused by high dynamic loads. In order to have a higher reliability in shipboard power systems, presently more generators are kept online operating much below their efficient point. Hence, to improve the fuel efficiency of shipboard power systems, the minimum generator operation with N-1 safety can be considered as a simple solution, a tradeoff between fuel economy and reliability. It is based on the fact that the fewer the number of generators that are brought online, the more load is on each generator such that allowing the generators to run on better fuel efficiency region. In all-electric ships, the propulsion and service loads are integrated to a common network in order to attain improved fuel consumption with lesser emissions in contrast to traditional approaches where propulsion and service loads are fed by separate generators. In order to make the shipboard power system more reliable, integration of energy storage system (ESS) is found out to be an effective solution. Energy storage devices, which are currently being used in several applications consist of batteries, ultra-capacitor, flywheel, and fuel cell. Among the batteries, lithium-ion is one of the most used type battery in fully electric zero-emission ferries with the shorter route (around 5 to 10 km). Hybrid energy storage systems (HESSs) are one of the solutions, which can be implemented in high power/energy density applications. In this case, two or more energy storage devices can be hybridized to achieve the benefits from both of them, although it is still a challenge to apply presently such application by a single energy storage device. The aim of this paper is to review several types of energy storage devices that have been extensively used to improve the reliability, fuel consumption, dynamic behavior, and other shortcomings for shipboard power systems. Besides, a summary is conducted to address most of the applied technologies mentioned in the literature with the aim of highlighting the challenges of integrating the ESS in the shipboard microgrids.

“…Here, we consider the MVDC IPES presented by Khan & Faruque (2017) from Florida State University, in which the power generation system comprises two 36 MW GTGs and two ATGs. For the purposes of this analysis, it is assumed that one of the 36 MW GTG sets is supplying power to the pulsed load as defined by Wolfe, et al (2005) and a 2 MW base load. This is consistent with the approach taken by Whitelegg (2016), when examining an AC power system.…”

SynopsisPower and energy have become a strategic and operational imperative for both the Royal Navy and United States Navy. The 21st century pace of change is unparalleled, with threats evolving at increased range, complexity, and sophistication. State and non-state adversaries are gaining technological advances and expanding their ability to conduct combined operations. Rapid fielding and seamless integration of advanced power and energy capabilities, such as power continuity across systems and electrically-powered weapons and sensors, will be critical for allies and partners to keep pace. As energy is one of the primary drivers for enhanced warfighting capability, these capabilities will be spurred by advances in power, energy and integrated system level controls. Further, the evolution of asymmetric threats will require disruptive and technologically superior solutions that create resilient networks and operate in a fully distributed manner.

“…They are needed for the generation of high voltages, as HPGs and batteries are usually operated at a few hundred volts. Inductances are also widely used in capacitive pulsed-power generators [36], [37]. But in this case, the aim is to achieve pulse shaping in order to generate the required pulse length and to limit the maximum current.…”

Abstract-This literature review addresses inductive pulsed power generators and their major components. Different inductive storage designs like solenoids, toroids and force-balanced coils are briefly presented and their advantages and disadvantages are mentioned. Special emphasis is given to inductive circuit topologies which have been investigated in railgun research such as the XRAM, meat grinder or pulse transformer topologies. One section deals with opening switches as they are indispensable for inductive storages and another one deals briefly with SMES for pulsed power applications. In the end, the most relevant inductor systems which were realized in respect to railgun research are summarized in a table, together with its main characteristics.
