“…As bidirectional power flow is not required in such an application, three-phase diode rectifiers are appealing options due to their structural simplicity, high energy efficiency, and low cost. They can readily be used with woundrotor synchronous generators [4,6]. Diode rectifiers are already used in the conventional electric propulsion systems to supply the dc links of propulsion electric drives.…”

“…Despite the fact that the overwhelming majority of present all-electric ships use ac distribution systems, the penetration of power electronic converters into power systems is increasing a tendency towards dc distribution systems [4][5][6]. The incentive for this transition lies in the challenges associated with the ship ac power systems on the one hand, and an increasing interest in integration of energy sources and storage devices with dc outputs on the other hand [5,7].…”

Growing concerns about environmental protection and oil prices have forced the transport industries to develop low emission, fuel efficient solutions. In the maritime sector, dc grids are being considered for commercial marine vessels to improve emission and fuel consumption. As a requirement for evaluation and optimization of the fuel consumption, this paper sets forth efficiency modeling and analysis of a shipboard dc power system. The studied dc hybrid power system includes diesel engines, synchronous generator-rectifier units, and a full-bridge bidirectional converter that incorporates an energy storage device into the system. Various loss components of different elements are analyzed in detail, which are finally simplified to be readily used in complex optimization algorithms.

Shipboard integrated power systems, the key enablers of ship electrification, call for effective power management control (PMC) to achieve optimal and reliable operation in dynamic environments under hardware limitations and operational constraints. The design of PMC can be treated naturally in a model predictive control (MPC) framework, where a cost function is minimized over a prediction horizon subject to constraints. The real-time implementation of MPC-based PMC, however, is challenging due to computational complexity of the numerical optimization. In this paper, an MPC-based PMC for a shipboard power system is developed and its real-time implementation is investigated. To meet the requirements for real-time computation, an integrated perturbation analysis and sequential quadratic programming (IPA-SQP) algorithm is applied to solve a constrained MPC optimization problem. Several operational scenarios are considered to evaluate the performance of the proposed PMC solution. Simulations and experiments show that real-time optimization, constraint enforcement, and fast load following can be achieved with the IPA-SQP algorithm. Different performance attributes and their tradeoffs can be coordinated through proper tuning of the design parameters.Index Terms-Integrated perturbation analysis and sequential quadratic programming (IPA-SQP), integrated power system (IPS), model predictive control (MPC), power management control (PMC), real-time optimization.

“…Studies or analyses of hypothetical MVDC systems for shipboard application have focused on specific aspects of systems that could become practical MVDC systems. For example, in Balog and Krein (2007) and Bash et al (2009), the authors examine a two‐bus architecture, essentially a port‐and‐starboard‐oriented, split‐plant operation of a shipboard power system. A schematic fragment generally illustrating this arrangement (but representing none of the references specifically) is shown in Figure 1.…”
