  1. 1. Protection of HVDC Grids Against Blackouts (Simulation)

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

    Författare :Amal Al-Ammari; Dinah Atchan; [2021]
    Nyckelord :High Voltage Direct Current HVDC ; Voltage derivative dv=dt algorithm; Traveling wave algorithm; PSCAD simulation; Multi-terminal grid; Fault detection; Threshold value; Offshore HVDC; DC breaker; Voltage collapse;

    Sammanfattning : In the search for green energy to combat climatechange, a shift from conventional energy sources such as coal,oil, and nuclear towards Renewable Energy Sources (RES) isneeded. This shift poses a threat to the stability of the powergrids as RES do not contribute with rotating mass in the system. LÄS MER

  4. 3. Architecture of Power

    Uppsats för yrkesexamina på avancerad nivå, KTH/Arkitektur

    Författare :Fredrik Wadensten; [2021]
    Nyckelord :Architecture; Stockholm; City planning; Urban planning; Urban space; Energy production; Hydropower; Renewable energy; Public space; Housing; Nacka; Renewal;

    Sammanfattning : The 34 silos at Jarlaberg today contain crude oil but after the lease of land expires at 2036 are refurbished and remade to hold 2 500 000 m3 of water from Stockholm archipelago. Sharing the industrial plot of the reworked silos are 13 buildings with 2000 households between them. LÄS MER

  5. 4. Exploring complex pathways in the climate change, vulnerability and conflict nexus in Alta Verapaz, Guatemala

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Caroline Long; Markus Hatting; [2018]
    Nyckelord :Climate Change; Violent Conflict; Vulnerability; Adaptive Capacity; Fragility; Resilience; Governance; Land-grabbing; Social Sciences;

    Sammanfattning : The climate change and conflict nexus has been the focus of much debate and speculation in academic circles as well as public discourse. Much of the existing research has been undertaken by studies using quantitative methods, which intend to prove or disprove the existence of a causal relationship. LÄS MER

  7. 5. Utilization of Horizontal-Axis Tidal Stream Turbines As a Main Power Supply System On Offshore Remote Oil&Gas Platforms

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