This paper has introduced an algorithm for the identification of islanding events in remotely located distribution grid with renewable energy (RE) sources using voltage signals. Voltage signal is processed Stockwell transform (ST) to compute median-based recognition factor (MIRF). The rate change root mean square (RMS) computed by differentiating RMS respect time (VRCIRF). proposed voltage-base...

grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. mobile computing is a generic word that introduces using of movable, handheld devices with wireless communication, for processing data. mobile computing focused on providing access to data, information, services and communications anywhere an...

Smart grids allow more connectivity between the end-user and electric utility. Residential meters are replaced by smart meters, enabling near real-time communication customer company. The metering data serves to billing, monitoring, service delivery. However, interception of a malicious entity, or misused utility, could expose privacy. With this comes need protect privacy end-users. Literature ...

Smart grids are the cutting-edge electric power systems that make use of latest digital communication technologies to supply end-user electricity, but with more effective control and can completely fill end user demand. Advanced Metering Infrastructure (AMI), backbone smart grids, be used provide a range applications services based on AMI data. The increased deployment meters have attracted att...

Smart Grids are becoming a reality all over the world. Nowadays, the research efforts for the introduction and deployment of these grids are mainly focused on the development of the field of Smart Metering. This emerging application requires the use of technologies to access the significant number of points of supply (PoS) existing in the grid, covering the Low Voltage (LV) segment with the low...

Today, the development of information and communications technologies have changed the utility landscape dramatically. In particular, electricity distribution networks rely heavily on a multitude of intelligent systems and devices that communicate among each other in much more advanced ways than in the past. As the Smart Grid is becoming nowadays a critical component in the electricity delivery...

Objectives: The purpose of this study was to develop a new technique for analyzing velopharyngeal movement and to investigate its utility. Materials and Methods: Velopharyngeal motion of 20 normal individuals was analyzed. A three-dimensional (3D) endoscope was inserted into the oral cavity, and the movement of the soft palate was measured using an exclusive fixation device. Range images of the...

Smart grids, or intelligent electricity grids that utilize modern IT/communication/control technologies, become a global trend nowadays. Forecasting of future grid load (electricity usage) is an important task to provide intelligence to the smart gird. Accurate forecasting will enable a utility provider to plan the resources and also to take control actions to balance the supply and the demand ...

The paper outlines energy management concepts and the smart grid evolution. The necessity of considering energy management as a crucial innovation in load supplying to permit a more powerful penetration of renewable energy usage at the building and city level and to perform energy savings and CO2 emissions reduction is pointed out. The driving factors to enhance the current power distribution a...

Encountering the increasing demand for high-performance computational resources in academic as well as commercial organisations, utility computing offers a solution by providing users with on-demand availability of requested computing services. Approaches to the fundamental issue of resource allocation include the use of technical scheduling mechanisms as well as introducing economic ideas into...
