  1. 1. A Game-theoretical Framework for Byzantine-Robust Federated Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Wanyun Xie; [2022]
    Nyckelord :Game theory; distributed robust learning; training-time attacks; exploration-exploitation tradeoff; Spelteori; distribuerad robust inlärning; attacker på träningstiden; kompromiss mellan utforskning och exploatering;

    Sammanfattning : The distributed nature of Federated Learning (FL) creates security-related vulnerabilities including training-time attacks. Recently, it has been shown that well-known Byzantine-resilient aggregation schemes are indeed vulnerable to an informed adversary who has access to the aggregation scheme and updates sent by clients.

  2. 2. Congestion Management of EV Charging in Distribution Networks

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Adam Rosandell; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The societal integration of electric vehicles (EVs) imposes several challenges on the electrical grid, where congestion and overcurrents through related components are of focus for this thesis. Active network management through control systems is one flexible solution to this problem, and in the project Active Network Management for All (ANM4L), a congestion management algorithm utilizing PI controllers has been developed.

  3. 3. Techno-economic feasibility for residential Local Energy Communities: Case study of Italy

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Linda Colarullo; [2021]
    Nyckelord :Local Energy Community; Energy Sharing; Italy; Virtual Regulation Model; Distributed Renewable Energy Resources; Self-consumption maximization; Demand Side Management;

    Sammanfattning : The use of renewable energy has proven to be essential for the decarbonisation of the energy system, bringing changes on both the production and consumption side, with an increase of renewable energy in the mix and a change in the role of consumers. From passive actors, Consumers are becoming Prosumers (producers and consumers) of self-generated energy, with the potential of becoming the pillar of the energy sector transition. LÄS MER

  4. 4. Småhusens möjligheter att bidra med efterfrågeflexibilitet genom laststyrning av värmepumpar

    Kandidat-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Lukas Lindroos; Martin Sällström; [2021]
    Nyckelord :;

    Sammanfattning : Elförbrukningen i Sverige har ökat över tid men utbyggnaden av transmissionskapacitet har varit långsam, vilket har lett att stamnätet mellan norra och södra Sverige är ansträngt. Detta har resulterat i att vissa geografiska områden riskerar att drabbas av kapacitetsbrist under höglastperioder. LÄS MER

  5. 5. A Swedish Perspective on Aggregators and Local Flexibility Markets : Considerations and barriers for aggregators and SthlmFlex together with their potential to manage grid congestions in Stockholm

    Master-uppsats, KTH/Energiteknik

    Författare :Simon Färegård; Marko Miletic; [2021]
    Nyckelord :Demand side flexibility; aggregators; independent aggregators; congestion management; local flexibility markets; Eterfrågeflexibilitet; aggregatorer; oberoende aggregatorer; trängselhantering; lokala flexibilitetsmarknader;

    Sammanfattning : Aggregators targeting smaller customers, and their possibility to alleviate grid congestions through local flexibility markets, is a new concept in Sweden. The study’s purpose consisted of four main objectives. Investigate SthlmFlex and compare it to two other European flexibility markets. LÄS MER
