Resilience for Advanced Distributed Wind Systems: Identifying the resilience benefits of advanced controls and hybrid systems for distributed wind

“…The MIRACL team identified two existing distributed wind case studies for each lab to examine under the unique research areas. These case studies informed the research and served as proving grounds for the valuation, resilience, and advanced controls concepts developed under MIRACL [1]. We provide brief summaries here to provide context for when these case studies are referenced in the remainder of this report.…”

“…The first years of the project focused on bringing technical expertise to the areas of valuation, modeling, advanced controls, and resilience. The research developed by each lab was validated in two case studies, an isolated system in Alaska and a front-of-the-meter deployment in Iowa [1].…”

“…Frequency support is provided via active power control. Various means for accomplishing active and reactive power control are discussed thoroughly in other MIRACL reports but are not the focus of this paper [1].…”

“…However, if operators could rely on highly accurate wind forecasting, they wouldn't have to keep diesel generators spun up to provide reserve capacity and would only need to use the diesel generators when the wind generation was insufficient to meet the full load. This saves up to 28,000 gallons of diesel from being used throughout the year [1].…”
