Quantification Of The Impact Of Intermittent Renewable Penetration Levels On Power Grid Frequency Performance Using Dynamic Modeling, Elizabeth Ann Kirby

Graduate College Dissertations and Theses

As the technology behind renewable energy sources becomes more advanced and cost-effective, these sources have become an ever-increasing portion of the generation portfolios of power systems across the country. While the shift away from non-renewable resources is generally considered beneficial, the fact remains that intermittent renewable sources present special challenges associated with their unique operating characteristics. Because of the high variability of intermittent renewables, the frequency performance of the system to which they are connected can degrade. Generators assigned to regulate frequency, keeping it close to the desired 60 Hz, are forced to ramp up and down quickly in order …
