Increased penetration of renewable energy sources results in higher operating reserve requirements, due to the inherent variability and uncertainty of these resources. Many studies, primarily focusing on wind and solar, have determined that geographic diversity of variable renewables substantially reduces system variability and uncertainty. The Pacific Northwest is well suited...
Interest in renewable energy is on the rise, in both grid-connected operations and research projects. Major types of renewable energy include: wind, solar, wave, tidal, biomass, and geothermal. The majority are variable, non-dispatchable sources, which can have a negative impact on reserve requirements. This study focused on determining the optimal...
Renewable electrical energy sources are relatively easy to integrate at moderate penetrations, utilizing a combination of technical and market methods to increase grid flexibility. However, integrating high renewable portfolios is more challenging, and the optimal combination of resources will vary depending on the features of specific geographic areas. This study...
Power generation has been an ever growing exigency since the invention of electric power. The world is gradually inching away from conventional generation toward renewable generation. Advancements in renewable energy generation have been at a steady positive pace over the past few decades with different resources developing to be feasible...
Learning about periodic and oscillatory systems is a huge step in an undergraduate's
comprehensive understanding of physics and complex systems such as solids. However,
understanding how specific changes to such a system affect aspects of the entire system can
be difficult. The goal of this study is to create a...
A power inverter, or inverter, is an electronic device or circuitry that converts direct currents (DC) to alternating currents (AC) in the power electronics family. A three-phase inverter converts DC current to three-phase AC current. Inverters, especially three-phase inverters, have been widely used in many fields including renewable energy applications...
This work explores the synthesis and characterization of the metastable alloys Sn1-xCaxCh (Ch= S, Se) and nitride compounds Zn-W-Mo-N, which have recently been predicted by theorists. Single phase thin films of Sn1-xCaxS are prepared by pulsed laser deposition and radio-frequency magnetron sputtering and of Sn1-xCaxSe are prepared by pulsed laser...
