  1. 1. Data streaming provenance in advanced metering infrastructures

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Zozk Mohamed; [2023-11-24]
    Keywords : Advanced Metering Infrastructure; Ananke; Apache Flink; Göteborg Energi; Provenance; Stream processing; Stream Processing Engine;

    Abstract : Increasing volumes of data in digital systems have made the traditional approach of gathering and storing all the data while analyzing it in bulks at periodic intervals challenging and costly. One such field is the electric grid market, which has started modernizing its aging grids into smart grids where Advanced Metering Infrastructures (AMIs) play a vital role. READ MORE

  3. 2. Extension of low voltage distribution by pure DC or mixed AC/DC parts for integration of solar PV and EV charging

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sofie Jiang; [2022]
    Keywords : LVDC; LVAC; solar PV system; electric vehicle charging station; IKN-regulation; distribution system; RES integration; LVDC; LVAC; solceller; elfordon; laddstolpar; IKN-regelverk; distributionsnät; förnyelsebara energikällor;

    Abstract : This work examines the local distribution system in two residential areas in two Swedish towns, Oxelösund and Karlskrona, and studies how integration of PV systems and electric vehicle (EV) charging stations (CS) will affect the present distribution system. The research questions focus on the economic feasibility of a LVDC system, how it compares to a traditional LVAC (low voltage alternating current) system from an economic and technical perspective, and the possibilities a LVDC system brings to other DC component applications.

  4. 3. Comparative life cycle assessment of two desiccant wheel dehumidifiers with industrial application

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Astrid Ortis; [2022]
    Keywords : Desiccant wheel dehumidifier; adsorption dehumidification; life cycle assessment LCA ; EU Taxonomy; Rotorsorptionsavfuktare; luftavfuktning; livscykelanalys LCA ; EU taxonomi;

    Abstract : Humans spend around 80 percent of their lifetime indoors. The humidity level plays an essential part in indoor climate, both in non-industrial applications, such as thermal comfort, and industrial ones. Dehumidification is a technology in the field of thermal comfort and indoor climate to control humidity levels. READ MORE

  5. 4. Life cycle assessment of hybrid systems for rural electrification in Bolivia

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sandu Seres; [2021]
    Keywords : Diesel; Stirling; Photovoltaic; impact category;

    Abstract : Bolivia is a developing country in South America. Many rural communities still lack access to electricity. The extension of the National Grid System to all rural communities is not feasible due to economic and topographic challenges as well as the environmental problems that may arise. To tackle these problems, Off-grid solutions are implemented. READ MORE

  6. 5. Determining and analysing production losses due to ice on wind turbines using SCADA data

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Oscar Felding; [2021]
    Keywords : Wind turbines; ice accretion; ice losses; SCADA; cold climate; Vindturbin; ispåbyggnad; isförluster; SCADA-data; kallt klimat;

    Abstract : Wind turbines are becoming a more common sight and a more important part in the power grid. The benefits are mainly that wind energy is a renewable energy source and a single wind turbine can produce enough electricity to cover several households’ annual electricity need and not producing carbon dioxide as a rest product.
