Operational flexibility on complex enterprises : case studies from recent military operations
… requirement for 21st century enterprises is operational flexibility, a requirement particularly important for the U. S. Department of Defense (DoD). To achieve flexibility, most practice and research emphasizes process improvement, robust collaboration and "flattened" or "networked" …

Incorporating operational flexibility into electric generation planning : impacts and methods for system design and policy analysis
This dissertation demonstrates how flexibility in hourly electricity operations can impact long-term planning and analysis for future power systems, particularly those with substantial variable renewables (e.g., wind) or strict carbon policies. Operational flexibility describes a power system's …

Modeling and control of hybrid vapor compression cycles
… thermal energy storage unit to provide increased operational flexibility over the conventional unit. However, the gains associated with the increase in operational flexibility can only be achieved with the inclusion of appropriate control strategies to regulate and optionally optimize the energy …

25cc HCCI engine fueled with Diethyl Ether
… to operate in HCCI mode with surprising ease and flexibility. A 25cc, four-stroke, single cylinder Honda GX25 engine, possessing 2-valves with an overhead cam and separate oil sump lubrication system was used. This research aimed to provide insight with respect to which engine characteristics such …

Maximizing AUV slow speed performance
… with vehicle controls can be reduced and operational flexibility improved with relatively simple, low cost improvements. Because the operating speed that minimizes forward drag is not necessarily the same as that required for optimum sensor performance, a variable speed capability …

Unit commitment : tight formulation and pricing
… efficient GEP model that represents operational flexibility limits. Next, we present a tight formulation for the commitment of combined-cycle units with representation of their transition ramping. Finally, we propose a pricing method that reduces out-of-market payments in …

Integrated network-based thermofluid model of a once-through boiler at full- and part-load
… energy sources in South Africa requires greater operational flexibility of existing coal-fired power plants (CFPPs). Operational flexibility implies that power plants need to operate intermittently or at low load for extended periods. Existing CFPPs are designed to operate at a steady baseload. …
