Smart Distributed Generation Systems Using Improved Islanding Detection And Event Classification, Bikiran Guha
Electronic Theses and Dissertations
Distributed Generation (DG) sources have become an integral part of modern decentralized power systems. However, the interconnection of DG systems to the power grid can present several operational challenges. One such major challenge is islanding detection. Islanding occurs when a DG system is disconnected from the rest of the power grid. Islanding can present serious safety hazards and therefore an accurate and fast islanding detection technique is mandated by DG interconnection standards such as IEEE 1547 and UL 1741. Conventional islanding detection techniques passively monitor the local power system parameters such as voltage and frequency to detect islanding. These techniques …

Comparing The Efficiency Of Heterogeneous And Homogeneous Data Center Workloads, Brandon Kimmons
Electronic Theses and Dissertations
Abstract
Information Technology, as an industry, is growing very quickly to keep pace with increased data storage and computing needs. Data growth, if not planned or managed correctly, can have larger efficiency implications on your data center as a whole. The long term reduction in efficiency will increase costs over time and increase operational overhead. Similarly, increases in processor efficiency have led to increased system density in data centers. This can increase cost and operational overhead in your data center infrastructure.
This paper proposes the idea that balanced data center workloads are more efficient in comparison to similar levels of …
