    Sammanfattning : 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. LÄS MER

  4. 18. Uncertainty modeling for load flow and hosting capacity analysis of urban electricity distribution systems

    Författare :Umar Hanif Ramadhani; Joakim Widén; Joakim Munkhammar; Bri-Mathias Hodge; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty model; Photovoltaics; Electric vehicle; Residential buildings; Hosting capacity; Probabilistic load flow; Electricity distribution systems; Urban Energy Systems; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : Urban demographics are changing, with more than half of the global population currently residing in urban areas. Traditionally, cities are often seen as passive energy consumers relying on external centralized systems. Motivated by the need to mitigate climate change, a shift is underway as cities actively shape energy systems. LÄS MER

  5. 19. On Optimization Based Control of Distributed Energy Resources in Power Systems: Electricity Markets and Voltage Regulation Perspectives

    Författare :Pavan Balram; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model predictive control and distribution systems; Electric vehicles; electricity markets; coordinated voltage control; battery energy storage; photovoltaics;

    Sammanfattning : Distributed energy resources are increasingly being integrated into power systems around the world. These resources, typically connected at the distribution system level, are already changing the pattern of power flow from being unidirectional to multidirectional. LÄS MER
