  5. 4. Optimal Allocation of Smart Meters to Real or Virtual Data Concentrators

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Christian Johansson; [2015]
    Nyckelord :;

    Sammanfattning : The Smart Grid is the new, modernized, electrical distribution grid. It allows for many applications such as automation, reliability and efficiency of electrical distribution. A key feature of the smart grid is the AMI (Advanced Metering Infrastructure) which is the system that measures, collects and analyzes energy use. LÄS MER

  7. 5. Pilotinstallation av fast och fjärravläst nätstationsmätning : Identifiering av för- och nackdelar med nätstationsmätning, Mälarenergi Elnät AB

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Malin Johnsson; [2014]
    Nyckelord :nätstationsmätning; nätförluster; mätosäkerhet; effektiviserings potential; lågspänning;

    Sammanfattning : Today’s electrical grid companies understand that better knowledge of and information about their grid can help realize a smart grid network. One way to gain better knowledge and information about the low voltage network is to install measuring equipment on the substation transformer´s secondary low voltage side that measures the low voltage network losses for that specific substation.
