Market-Based Control of Shipboard Engineering Plants
Abstract
The overall goal of the proposed research is to develop a market-based control method for shipboard IEPs. This goal will be realized through the following objectives.Objective 1: Formulate market-based control methodThe proposed market-based control method must be mathematically formulated. This requires the development of control methods for the consumer (the CO) and for firms (the equipment within the IEP) and the integration of these control methods to form the overallmarket-based control system for shipboard IEPs.Objective 2: Evaluate market-based control method performanceThe performance of the proposed market-based control method must be evaluated. First, an appropriate notional IEP will be identified; performance metrics and operational scenarios will be selected. Then, the market-based control method will be assessed in steady-state under various conditions and during dynamic events caused by changes in mission or plant lineup orequipment failures. Finally, the small- and large-signal stability of the market-based control method will be analyzed.Objective 3: Identify the impact of market-based control method on system design How and to what extent the use of the proposed market-based control method will affectthe design of shipboard IEPs must be identified. Highly successful early-stage design techniques for shipboard engineering systems often assume quasi-optimal behavior from the control system[18], [19]. This is a limiting assumption necessitated by the difficulty of modeling existing control approaches during the early design stage. It is desirable to understand how the application of the market-based control method will affect the arrangement, sizing, and configuration of IEP components. As the market-based control method is generalizable to various shipboard IEPs, it is possible to represent it effectively during the early design stage. This is not possible with existing control methods because they are generally based on specific IEP designs and cannot be well understood until more detailed design is performed. An understanding of the impact of the market-based control method on system design can lead to standards development that will facilitate an open-architecture approach and wide-scale application of the control method.
