Optimization-Based Integrated Voltage And Frequency Support For Microgrids Using Energy Storage Systems, Niranjan Bhujel
Optimization-Based Integrated Voltage And Frequency Support For Microgrids Using Energy Storage Systems, Niranjan Bhujel
Electronic Theses and Dissertations
Microgrids have emerged as a promising solution for ensuring the reliability and resilience of future grids, especially with the increasing integration of distributed energy resources (DERs) such as solar, wind, and energy storage systems (ESSs). However, this integration presents significant challenges in the dynamic control of voltage and frequency. Microgrids exhibit a distinctive characteristic marked by a high R/X ratio, resulting in voltage sensitivity to both active and reactive power, while frequency sensitivity is confined to active power. This unique attribute often leads to interference between voltage and frequency support schemes, potentially triggering protection mechanisms and causing localized or cascaded …

Active Blade Pitch And Hull-Based Structural Control Of Floating Offshore Wind Turbines, Eben Lenfest
Electronic Theses and Dissertations
Floating offshore wind turbines (FOWTs) have the potential to bring renewable energy to waters too deep for traditional offshore wind turbines while still being able to harness strong coastal winds in areas near population centers. However, these floating wind turbines come at a higher capital cost relative to fixed foundations and are more susceptible to vibrations induced by waves. Advances in control technologies offer the potential to reduce fatigue loads due to these vibrations, extending the life of the platform and thereby spreading the capital costs of the turbine over a longer period of time. One such advance is in …
