The variable output of renewables such as wind and solar causes fluctuations of power flow that can adversely affect power system operation, especially at high levels of penetration. The coordination of multiple energy storage solutions can mitigate integration challenges by providing a buffer from variable renewables. This thesis presents the...
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 collocated with wind farms can improve
dispatchability of the...
This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term...
Over the last 20 years, there has been rapid growth in the amount of installed wind power in the Pacific Northwest, specifically in the Columbia River Gorge. The variable and non-dispatchable nature of this resource requires that it be balanced in some form by other sources on the grid. In...
The Norwegian-Swedish Crisis of 1905 is unique because the two
kingdoms, united in a dual monarchy, separated peacably. The thesis
raises three questions: why did Norway want independence at all, why
was the secession peacable, and can any of the factors which solved
the Crisis of 1905 be injected or...
