Evolution of Metric-Based Assessment of Shipboard Power System Performance

Grants and Contracts Details


This project aims to transform the evaluation of shipboard power system performance through the advancement of metric-based assessment methods. By developing innovative approaches, this project seeks to provide a comprehensive and dynamic framework for assessing the performance of shipboard power systems in various mission contexts. The project focuses on three main objectives. The first objective aims to advance mission analysis-driven approaches in measuring system performance. By bridging the gap between conventional operability evaluation and optimal control-based evaluation, the project aims to develop methodologies that consider the dynamic interplay between the power system and mission requirements. This will lead to a more accurate and comprehensive assessment of system performance, enhancing the understanding of mission requirements from the power system perspective. The second objective focuses on decomposing mission analysis approaches using a hierarchical system of systems formulation. By breaking down the shipboard power system into multiple subsystems and capturing their interdependencies, the project aims to develop a hierarchical model that accurately represents the complex nature of the system. This decomposition will enable a more granular evaluation of system performance, considering the interactions and dependencies between subsystems, and facilitate the development of optimized control strategies. The third objective involves quantifying the cost of information and control requirements on system performance. By developing methods to assess the trade-offs between performance and the resources needed for information acquisition and control implementation, the project aims to support cost-effective decision-making in shipboard power systems. This will provide insights into the optimal level of information and control required to achieve a certain level of performance, considering the associated costs. Throughout the project, advanced techniques such as optimal control and Markov decision processes will be employed to develop algorithms and models that capture the dynamic and stochastic nature of shipboard power systems. The developed methodologies, hierarchical system models, and optimization algorithms will be validated using realistic shipboard power system contexts, leveraging experimental data for calibration and verification. The outcomes of this research will have significant implications. The enhanced assessment methods and optimized control strategies will enable naval vessels to operate more efficiently, sustainably, and effectively in a range of mission environments. Ultimately, the project aims to enhance the operability of shipboard power systems while reducing the cost of system operation, leading to improved mission effectiveness, reduced fuel consumption, and extended range and endurance of naval vessels. This project represents a significant step towards achieving advanced performance assessment and control strategies in shipboard power systems. It has the potential to drive innovation in naval operations and contribute to the overall advancement of maritime capabilities.
