  1. 1. Optimering av flyghastighet för flygplan

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Louise Larsson; [2023]
    Nyckelord :Aircraft flight speed; flight operations; speed optimization; Cost Index; ECON speed; Flyghastighet; flygverksamhet; hastighetsoptimering; kostindex; ekonomisk hastighet;

    Sammanfattning : Optimization of flight operations is a way to reduce the impact of aviation on the environment and make the use of airspace more effective. Reductions in fuel consumption and flight time are further desired by airlines to minimize operational costs. LÄS MER

  3. 2. Reasoning about Moving Target Defense in Attack Modeling Formalisms

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

    Författare :Gabriel Ballot; [2022]
    Nyckelord :Timed Model checking; Cyber Security; Threat Modeling; Moving Target Defense; Tidsinställd modellkontroll; Cybersäkerhet; Hotmodellering; Moving Target Defense;

    Sammanfattning : Since 2009, Moving Target Defense (MTD) has become a new paradigm of defensive mechanism that frequently changes the state of the target system to confuse the attacker. This frequent change is costly and leads to a trade-off between misleading the attacker and disrupting the quality of service. LÄS MER

  4. 3. System perspective of rooftop solar PVs in the Swedish industry sector : A case study of GEHAB in Småland

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Tim Wisme; [2022]
    Nyckelord :Cost-efficient energy solutions; Photovoltaic power; Solar PV; Electricity storage; Lithium-ion battery; Emission reduction; energy simulations; EnergyPLAN;

    Sammanfattning : To reach the Swedish goal of reaching a completely fossil-free electricity sector by the year 2040, there is a need for an increased rate of installed renewable electricity sources. Companies have the opportunity to work towards this goal by investing in solar power technologies, which results in a lowered electricity bill, and an additional revenue when electricity is sold to the grid.

  5. 4. Estimating CO2 reductions from renewable energy sources : The impact of power system nonlinearities

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

    Författare :Kristoffer Berglund; [2022]
    Nyckelord :CO2 reduction; Dispatch model; Econometric model; Unit commitment; CO2-reduktion; ekonometriska modeller; produktionssimuleringsmodeller;

    Sammanfattning : Replacing conventional generation with renewable generation in power systems is essential for reducing CO2 emissions. It is important to know how effective renewables are in reducing CO2 emissions. Since CO2 reduction cannot be measured directly, different methods have been used to estimate reduction of CO2 emissions. LÄS MER

  7. 5. A case study about the potential of battery storage in Culture house : Investigation on the economic viability of battery energy storage system with peak shaving & time-of-use application for culture house in Skellefteå.

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Baljot Singh; [2021]
    Nyckelord :Battery energy storage system; power grid; peak shaving; time-of-use; tariff system; battery aging; state of health; and second-life batteries.;

    Sammanfattning : The energy demand is steadily increasing, and the electricity sector is undergoing a severe change in this decade. The primary drivers, such as the need to decarbonize the power industry and megatrends for more distributed and renewable systems, are resulting in revolutionary changes in our lifestyle and industry.
