Abstract
  • Generating abundant, renewable energy from Earth’s oceans is an attractive option for meeting increasing energy demand. Marine renewable energy also comes with the variability of renewable sources, which impact the reliability and power quality of the electrical grid. On a transmission-level, this dissertation looks at ensuring reliability of the power system with both reactive reserves and minimizing loop flows. Clustering of the power flow analysis with Voltage Control Areas (VCAs) simplifies analysis of reactive reserves and serves as the basis for quantifying the effects a wave energy converter (WEC) has on transmission system loop flows. Proper WEC placement can minimize loop flow effects. On a device-level, WEC can cause issues with the power quality at the point of connection to the grid. The author uses a hybrid-simulated WEC to measure electrical power quality phenomena in a laboratory setting with a numerically modeled WEC. This setup ensures realistic power-quality results while reducing the expense necessary to test a grid-connected WEC.
