Improving Wind Farm Dispatchability Using Model Predictive Control for Optimal Operation of Grid-Scale Energy Storage

Halamay, Douglas; Antonishen, Michael; Lajoie, Kelcey; … - In: Energies 7 (2014) 9, pp. 5847-5862

This paper demonstrates the use of model-based predictive control for energy storage systems to improve the dispatchability of wind power plants. Large-scale wind penetration increases the variability of power flow on the grid, thus increasing reserve requirements. Large energy storage systems...

Does a Change in Price of Fuel Affect GDP Growth? An Examination of the U.S. Data from 1950–2013

Aucott, Michael; Hall, Charles - In: Energies 7 (2014) 10, pp. 6558-6570

We examined data on fuel consumption and costs for the years 1950 through 2013, along with economic and population data, to determine the percent of U.S. gross domestic product (GDP) spent each year on fuels, including fossil fuels and nuclear ore, and the growth of the economy. We found that...
