  1. 1. Comprehensive Study of Meta-heuristic Algorithms for Optimal Sizing of BESS in Multi-energy syste

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

    Author : Joakim Ginste; [2022]
    Keywords : BESS; Energy arbitrage; Firefly algorithm; Genetic algorithm; Peak shaving; BESS; energiarbitrage; Firefly algorithm; Genetic algorithm; spetslastutjämning;

    Abstract : The question of finding the optimal size for battery energy storage systems (BESS) to be used for energy arbitrage and peak shaving has gained more and more interest in recent years. This is due to the increase in variability of electricity prices caused by the increase of renewable but also variable electricity production units in the electricity grid. READ MORE

  3. 2. Development of heat recovery solution for heavy duty truck cabs to improve energy efficiency.

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

    Author : Exekiel Aurelio; Rahul Acharya Rathnakar; [2022]
    Keywords : air-to-air heat recovery; air-to-liquid heat recovery; integrated thermal management system; heat wheel; heat pump; battery electric vehicle; battery electric trucks; energy savings.; luft-till-luft värmeåtervinning; luft-till-vätska värmeåtervinning; integrerat värmehanteringssystem; värmehjul; värmepump; batterielektriskt fordon; batterielektriska lastbilar; energibesparingar.;

    Abstract : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). READ MORE

  4. 3. Behaviour of NOx sensors at their end of life

    University essay from KTH/Förbränningsmotorteknik

    Author : Jose Mathew; [2020]
    Keywords : NOx sensor; failure modes; oscillatory fault monitor; diagnosis of sensors; NOx sensor; felfunktioner; oscillerande felmätare; diagnos av sensorer;

    Abstract : NOx-sensorn är grundläggande i det moderna efterbehandlingssystemet och dess pålitlighet är avgörande för att kunna leva upp till rådande emissionslagkrav. Livslängden samt sensorns beteende i slutet av denna varierar betydligt. READ MORE

  5. 4. Catching Ash : Methodology for ash accumulation in diesel particulate filters

    University essay from KTH/Materialvetenskap

    Author : Charis Pavlou; [2019]
    Keywords : diesel engine; diesel particulate filter; particulate matter; testing rig; accelerating ash accumulation;

    Abstract : The diesel particulate filter captures particulate matter that is produced in the diesel engine. A small fraction of particulate matter is comprised by ash forming matter. When the combustible fraction of particulate matter is removed from the filter, the ash, which is incombustible, remains. READ MORE

  6. 5. Preparation for a Thermal Balance Test of the MIST student satellite

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

    Author : Fredrik Unell; [2019]
    Keywords : ;

    Abstract : The MIST project was founded in 2014 at KTH and has been worked on by roughly 100 students since.Thermal engineering has been an important part of the project from start and a thermal model has beendeveloped to predict ight conditions. The thermal model created by previous students has to be correlatedby performing a thermal balance test. READ MORE
