“…To enable effective integration, the power system design authority must have a complete understanding of the power system performance envelope, from both an electrical and mechanical perspective, when subject to pulse type loading. Understanding around the impact of pulse loads on power system performance from an electrical perspective has increased in recent years (Daffey & Hodge, 2004) (Lewis, 2006) (Tsekouras, Kanellos, Prousalidis, & Hatzilau, 2010), with energy storage referenced as an enabling technology (Gonsoulin, Vu, & Diaz, 2017) (Khan & Faruque, 2017).…”

Future warship power systems may be subject to pulsed loads manifesting through emergent combat systems such as directed energy weapons, associated sensors and electronic warfare equipment. The integration of combat system loads with the ship’s power system means that performance becomes intrinsically linked to combat effectiveness. Hence, understanding the capability of the power system to service such loads is vital in ensuring the operator’s ability to fight the ship. This paper describes the challenge of pulse load integration from the perspective of the power system design authority. Modelling and simulation has been employed to study the electrical response of a representative power system when subject to a range pulse load characteristics. Subsequently, the effects of pulse loading are reviewed in terms of impact upon the prime mover. It is concluded that whilst electrical supply performance can be maintained within allowable power quality limits as defined by STANAG 1008, the mechanical effects can be to the detriment of engine life, highlighting key recommendations to understand both electrical and mechanical performance envelope in design for integration.

“…In [14], the researchers presented an MPC-based ship power management controller to coordinate sources and loads based on future demand dynamically. A shipboard centralized MPC is proposed to optimize the coordination of the energy storage and diesel gen-sets (DGs) [15]. Hou et al [16] designed pre-filtering MPC and coordinated control MPC method for ship power system to address the power flow tracking between super-capacitors and battery devices, and at the same time to achieve energy saving under various operating constraints.…”

The electrified hybrid shipboard power system with high-level integration of renewable energy resources and energy storage system has become the new trend for the all-electric ship (AES) configuration. However, the traditional energy management system (EMS) is not able to fulfill the increasingly complex control requirements, and a more advanced EMS control algorithm is required to handle the multiple power sources and even achieve optimal energy management control. This paper proposes supervisory energy management with an improved adaptive model predictive control (AMPC) strategy to optimize the power split of the hybrid power sources and to reduce the total cost of ownership (TCO) of vessel operation, which considers not only the fuel and emission cost but also the power source degradation. In order to achieve realtime implementation, the AMPC-based EMS software has been developed and deployed to a programmable logic controller (PLC) hardware. A hybrid fuel cell-fed shipboard power system with a DC-grid configuration is modeled and operated on a hardware-in-the-loop (HIL) setup. The prototyping controller verification tests have been performed with this HIL plant in the lab environment. Three typical tugboat load profiles with power fluctuations are implemented as case studies. Lastly, a cost study was carried for a ten-year long-term vessel operational cycle. The proposed AMPC-based EMS can achieve up to 12.19% TCO savings compared to those of a traditional rule-based control strategy.

“…Although much has been published on the control of this type of ESS to smooth electric power system dynamics (Gonsoulin, Vu, & Diaz, 2017) (Khan & Faruque, 2017) (Langston, Stanovich, Schoder, & Steurer, 2017), ESS requirements to ensure engine MTBO at least equal to that of current generation warships have not been fully articulated. Hence, the following section explores the requirements of the ESS to maintain acceptable engine MTBO while also meeting the P&E requirements of a large pulsed load.…”

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.
