This paper presents an overview of the smart energy campus project at Georgia Tech, which uses a living smart grid test-bed. The test-bed covers 200 buildings with more than 400 smart meters and sub-meters. It has a variety of load components including industrial load, commercial office building loads and residential loads. Renewable energy such as PV system and electric vehicle charging statio...

In this paper, we use experimental data collected from an Austin, Texas smart grid test bed with a system-level battery energy storage model to assess the lifetime of batteries in a microgrid operating in islanded mode during a distribution-level outage. We consider a hypothetical microgrid consisting of 21 single-family detached homes and three transformer-level community energy storage (CES) ...

At present, the solutions to prevent bedsore include using various techniques for movement and displacement of patients, which is not possible for some patients or dangerous for some of them while it also poses problems for health care providers. On the other hand, development of information technology in the health care system including application of wireless sensor networks (WSNs) has led to...

In this paper we describe the design and evaluation of the prototype vehicle for a new test-bed developed for multi-vehicle control, navigation and communication. The vehicle is designed for high reliability and easy recon guration using smart sensor and actuator interfaces. It is passively stable in pitch and roll and is actuated by ve thrusters. The actuators allow for full control of the rem...

Active spaces and smart rooms are quickly gaining popularity in both the research arena, and in commercial projects. Active spaces are physical spaces populated with massive numbers of specialized embedded computing devices that increase human productivity by enabling users to interact seamlessly with the surrounding environment. Security for active spaces is necessary. In such settings, it is ...

Synchrophasors are the state-of-the-art measuring devices that sense various parameters such as voltage, current, frequency, and other grid parameters with a high sampling rate. This paper presents an approach to visualize and analyze the smart-grid data generated by synchrophasors using a visualization tool and density based clustering technique. A MATLAB based circle representation tool is ut...

The electricity grid is the backbone of the power network and is at the focal point of technological innovations. Utilities need to introduce distributed intelligence into their existing infrastructure to make them more reliable, efficient, and capable of exploiting and integrating alternative sources of energy. The intelligent grid includes the infrastructure and technologies required to allow...
