“…In [17], dynamic programming (DP) algorithm is adopted to solve the same problem. In [18], the authors formulated a multi-objective problem that considers the reduction of fuel consumption and energy efficiency operation indicator (EEOI) limitation together. In the above works, they do not consider the failure mode.…”

Optimal power management of shipboard power system for failure mode (OPMSF) is a significant and challenging problem considering the safety of system and person. Many existing works focused on the transient-time recovery without consideration of the operating cost and the voyage plan. In this paper, the OPMSF problem is formulated considering the mid-time scheduling and the faults at bus and generator. Twoside adjustment methods including the load shedding and the reconfiguration are coordinated for reducing the fault effects. To address the formulated non-convex problem, the travel equality constraint and fractional energy efficiency operation indicator (EEOI) limitation are transformed into the convex forms. Then, considering the infeasibility scenario affected by faults, a further relaxation is adopted to formulate a new problem with feasibility guaranteed. Furthermore, a sufficient condition is derived to ensure that the new problem has the same optimal solution as the original one. Because of the mixed-integer nonlinear feature, an optimal management algorithm based on Benders decomposition (BD) is developed to solve the new one. Due to the slow convergence caused by the time-coupled constraints, a low-complexity near-optimal algorithm based on BD (LNBD) is proposed. The results verify the effectivity of the proposed methods and algorithms.

“…It is recognized extensively that the all-electric ship paradigm is aligned entirely with the requirements of better efficiency, fuel economy, and better levels of power quality and reliability [1][2][3][4][5]. Furthermore, easier functional integration of electrical components and subsystems is achieved, and more effectiveness can be achieved in realizing cold ironing while the ship is berthing [6][7][8].…”

“…As evidenced in recent literature, modern ships' loads and generators include various electrical subsystems [3,4,7,12,13]. As an example, in the scheme depicted in Figure 1, which is based on the MVDC power distribution architecture, DC-DC converters allow the adjustment of the different devices that are connected to different voltage levels.…”

Design and Control of Coupled Inductor DC–DC Converters for MVDC Ship Power Systems

This paper deals with the design and control aspects of modern ship power systems within the paradigm of an all-electric ship. The widespread use of power electronic converters is central in this context due to the technological advances in automation systems and the integration of the electrical propulsion systems and other components, such as electrical energy storage systems and renewable energy sources. The issue to address in this scenario is related to the request of increased performances in dynamic operation while pursuing advantages in terms of energy savings and overall system security. In addition, the presence of large load changes requires providing robustness of the control in terms of system stability. This paper is focused on medium voltage direct current (MVDC) ship power systems and the design and control of coupled inductor DC–DC converters. The load is handled in terms of a constant power model, which generally is considered the most critical case for testing the stability of the system. The robustness of the design procedure, which is verified numerically against large and rapid load variations, allowed us to confirm the feasibility and the attractiveness of the design and the control proposal.
