2. 1. On possibilities of smart meters switching at low voltage level for emergency grid management

   Author : Yasir Arafat; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution grid; Smart grid; Remote switching; Smart meter.; Power quality; Power quality measurement;

   Abstract : Smart Meter (SM) is an advanced remotely readable energy meter with two-way communication capability which measures the electrical energy in real-time or near-real-time and securely sends data to Distribution System Operator (DSO). A smart metering system is an application of SMs on a larger scale, i.e. READ MORE

4. 2. Quality Assurance of Time Critical Data Using Adaptive Data Delivery Mechanisms in Smart Grids

   Author : Yiming Wu; Lars Nordström; Chen-Ching Liu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time critical data quality; adaptive mechanisms; quality assurance; Smart Grid; information resiliency; data accuracy; end-to-end latency; cyber-security; substation automation; power system communication; Electrical Engineering; Elektro- och systemteknik; Industrial Information and Control Systems; Industriella informations- och styrsystem;

   Abstract : Smart grids are proposed to integrate renewable energy and to improve the efficiency of power system operation. The challenges of integrating renewable energy are the inherent fluctuations of generation which are difficult to predict which may lead to challenges to the safe operation of power systems.

5. 3. Towards Intelligent Power-System Monitoring: Segmentation, Feature Extraction, and Identification of Underlying Causes

   Author : Cuong Le; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; harmonics analysis; Power-system monitoring; segmentation; power-system measurement; power quality; event analysis; signal-processing applications;

   Abstract : The increase in size of modern power systems together with the concept smart grid requires advanced monitoring to ensure system availability, reliability, and power quality. The huge amount of available data no longer permits analysis to be implemented manually and centrally. READ MORE

6. 4. On Possibilities of Using Smart Meters for Compulsory Load Shedding Supported by Load Forecasting

   Author : Yasir Arafat; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power quality; Remote switching; Electrical distribution system; Smart meter; Compulsory load shedding; Load forecasting;

   Abstract : The smart meter rollout is progressing in several parts of the world with early adoption in some parts, e.g., Europe. Remote ON/OFF control switch of the smart meter allows distribution system operators to switch the smart meter of any customer remotely. READ MORE

7. 5. Modeling and constructing unstructured overlay networks: Algorithms, techniques and the Smart Grid case

   Author : Georgios Georgiadis; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; matching; smart grid; online computation; scheduling; unstructured overlays; random walks; natural computing; resistor networks; clustering;

   Abstract : Throughout its lifetime, the Internet was always associated with overlay networks; from the WorldWideWeb and peer-to-peer networks to blogs and social networking solutions, overlays built on the Internet infrastructure gave it additional value and made it more engaging to everyday users. Today, rising overlay networks such as the Smart Grid as well as a multitude of sensor, mobile andwireless networks herald a new era of unprecedented connectivity and networking. READ MORE
