2. 1. Assembling the Smart Grid : On the Mobilization of Imaginaries, Users and Materialities in a Swedish Demonstration Project

   Author : Anna Wallsten; Harald Rohracher; Jonas Anshelm; Vasilis Galis; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Smart grids; demonstration projects; translations; sociotechnical imaginaries; material participation; users; Smarta elnät; demonstrationsprojekt; översättning; sociotekniska föreställningar; material participation; användare;

   Abstract : Influential actors refer to smart grids as a revamped version of the energy systemwhen they argue for alternative energy pathways, and assign demonstration projects with the task of turning prospects about the future into functional configurations. This thesis explores notions of the smart grid future that are implicitly conveyed in Swedish smart grid strategy and planning documents. READ MORE

4. 2. 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

5. 3. Synergy between Photovoltaic Power Generation and Electric Vehicle Charging in Urban Energy Systems : Optimization Models for Smart Charging and Vehicle-to-Grid

   Author : Reza Fachrizal; Joakim Munkhammar; Mahmoud Shepero; Joakim Widén; Johan Driesen; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; Photovoltaics; Smart Charging; Vehicle-to-Grid; Urban Energy Systems; Load Matching; Self-Consumption; Optimization; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Abstract : Cities are responsible for around 75% of global primary energy use and 70% of global greenhouse gas (GHG) emissions, with buildings and urban mobility being two key contributors. Actions to reduce GHG emissions have been promoted and implemented in many countries in the world. READ MORE

6. 4. 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

7. 5. Supermarket refrigeration systems for demand response in smart grids

   Author : Tommie Månsson; Chalmers tekniska högskola; []
