The Economic Load Dispatch problem concerns the determination of the optimal combination of power generators’ outputs with the lowest generation cost for a defined level of load. The problem arises from the fact that there are rated limits of generators’ power output, fuel costs of power plants are different, energy should be balanced, and plants are not located at the same distance from load c...

As part of the USDOE’s Carbon Sequestration Program, we have developed an integrated modeling framework to evaluate the performance and costs of alternative CO2 capture and storage technologies for fossil-fueled power plants, in the context of multi-pollutant control requirements. This model (called the IECM-CS) allows for explicit characterization of the uncertainty or variability in any or al...

Currently, many socially responsible governments adopt economic incentives and deterrents to manage environmental impacts of electricity suppliers. Considering the Stackelberg leadership of the government, the government’s role in the competition of power plants in an electricity market is investigated. A one-population evolutionary game model of power plants is developed to study how their pro...

T raditionally, nuclear power plants (NPPs) have been considered as baseload sources of electricity as they rely on a technology with high fixed costs and low variable costs. In the beginning of the nuclear era, the share of nuclear power in the overall energy mix was usually small, and adjustments of electric load in response to variations in electricity demand could be left to technologies wi...

The complexity of fusion power plants require the integration of many diverse and important system requirements to achieve a design approach that is viewed as a commercially viable electric plant. The ARIES-AT power core design builds upon a history of fusion power core designs that evolve along with physics and engineering advances. The baseline design point is optimized for maximum performanc...

The trend toward higher speed, higher power density liquid turbomachinery has inevitably increased the potential for fluid/structure interaction problems, and the severity of those problems. Fluid structure interaction phenomena can lead to increased wear and to structure failure. There are many factors affecting hydraulic and dynamic performance of pumping plants. These factors contribute to d...
