“…Up to now, according to the authors’ survey, tugs and yachts have been deployed using this type of propulsion system. Damen is a well‐known tugboat manufacturer pioneering the application of hybrid propulsion systems and providing hybrid power in 2014 101 . Also, yachts such as Savannah and Feadship launched in 2015 also chose hybrid propulsion systems.…”

“…This ship system (Fig. 2) is evaluated for its ability to supply power to 200 samples of various operational mission load profiles generated from a load demand model [34], [47]. These mission load profiles each represent a single tactical engagement over 600 s, which is sufficient time to fully exercise the power system via energy storage charge discharge, generator ramping, etc.…”

Shipboard power systems that service large-scale dynamic loads and electric propulsion can significantly improve their performance by adding controllable energy storage. These systems require power management controls that consider dynamics like generator ramp rates, along with energy storage capacity and location. In the early-stage design process, many alternative designs are considered, and each requires a unique controller. This paper describes a numerical optimization technique that establishes an upper bound performance criteria without manually designing controllers for each system. The solution is a best case performance that assumes perfect future knowledge of the time-varying load. While unrealistic in real-time, this technique yields a fair comparison between competing architectures without the variability of different control methods. To demonstrate the concept, a notional multi-bus power system architecture is evaluated on a representative set of operational duties to illustrate comparisons between system attributes like energy storage power and efficiency ratings. A design trade study shows that the success rate for a baseline ship can improve from under 60% to nearly 100% by increasing generator power by 10% and energy storage capacity by 100%. These automated architecture benchmarks fit into a broader total ship optimization process, or can be used in human-driven trade studies.

“…As outlined above, the power management is responsible for sharing generation on a relative basis and keeping voltages close to nominal. To test scenarios, information on loading profiles was used based on data from (Stevens et al, 2017) and simulated using the simplified zonal system model. The distributed controls keep the operating voltages at the five dual-winding PGMs within 2-3% of the desired setpoint.…”

A framework and testbed for evaluating system-level controls through quantifiable metrics has been developed following a hardware-in-the-loop approach. The testbed builds on a combination of real-time modelling and simulation, network communication and surrogate control platforms, and allows testing control algorithms early in the design and development cycle. The framework facilitates derisking and benchmarking of a wide variety of applications, but power, energy and reconfiguration management schemes for the notional zonal MVDC shipboard power system architecture are of primary interest. As part of the testbed developments, realtime dynamic simulation models of future naval shipboard power system have been implemented using several simulation platforms and various levels of fidelity. The second core testbed component is based on a heterogeneous set of controller platforms that allows realization of distributed controllers with a node count on the order of 100, each interfaced to a digital real-time simulator. Third, a dedicated network simulator provides a means to emulate computer networks linking simulation and controls. Extending previous efforts, this testbed significantly increases the hosting and evaluation capabilities of physically separate control units. To improve flexibility and affordability, surrogate control platforms were chosen that enable real-time execution but may not have all characteristics of the deployed hardware. As surrogate platforms and power system simulation are linked by digital communication means, the need for individual channel rewiring is avoided and replaced by automation for experiment reconfiguration, enabling the integrated testbed to support dynamic selection and execution of a large number of experiments.
