Title: Integrated Power and Energy Systems: System of Systems Engineering and Integration
Author(s): Tom Schubert and Greg Roach; Gibbs & Cox
Future trends in mission systems energy demands from sensors and effectors will represent a significant portion of the total electrical power demands on our ships, and in some cases will equal or even exceed propulsion and ship service hull, mechanical and electrical (HM&E) system demands. Integrated Power and Energy Systems (IPES) offer tremendous flexibility to manage the flow of power between these formerly independent and disconnected major shipboard systems. In order to enable this tradeoff of power supplied to mission systems vs. propulsion and HM&E systems, a thorough understanding of the interrelationships between these systems and their contributions to the overall mission effectiveness of the ship under a variety of operational scenarios and conditions is essential. This presentation will illustrate the trends in mission system loads relative to HM&E loads, and the need for an integrated, multidiscipline approach to developing and describing the power and energy requirements for each system, and then integrating those requirements to the total ship level for sizing power generation, power distribution and energy storage capabilities to ensure mission effectiveness under all operational conditions and scenarios for future combatants. Key system interfaces and ship integration considerations will be discussed to illustrate the complexity of this integration challenge. Finally, the author will discuss strategies to affordably accommodate future increases in power demand and the importance of integrating plans for HM&E upgrades with mission systems capability upgrades and technology insertions.
