  1. 36. Life Cycle Assessment of a small scale, solar driven HVR water purification system

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

    Författare :Sharang Kolathur; [2022]
    Nyckelord :life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Sammanfattning : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. LÄS MER

  3. 37. PV self-consumption: Regression models and data visualization

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

    Författare :Martos Tóth; [2022]
    Nyckelord :Self-Consumption; photovoltaics; battery; machine learning; solar energy; random forest; k-nearest neighbor; multi-layer perceptron; lasso regression; ridge regression; linear regression; Egenanvändning; photovoltaics; batteri; maskininlärning; solenergi; random forest; k-nearest neighbors; multi-layer perceptron; lasso regression; ridge regression; linjär regression;

    Sammanfattning : In Sweden the installed capacity of the residential PV systems is increasing every year. The lack of feed-in-tariff-scheme makes the techno-economic optimization of the PV systems mainly based on the self-consumption. The calculation of this parameter involves hourly building loads and hourly PV generation. LÄS MER

  4. 38. Hur kan en gammal industribyggnad med kulturhistoriskt värde göras om till bostäder? : En fallstudie av lokstallarna i Bollnäs

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :William Albeman; Emma Lif; [2022]
    Nyckelord :Re-use; Refurbish; renovate; distortion; industrial building; energy efficiency; Varsamhet; återbruk; ändringsarbete; industribyggnad; energieffektivisering;

    Sammanfattning : In Sweden there is a shortage of housing whilst old, abandoned industrial buildingstake up space on desirable land. These buildings generally do not live up to today’s standards regarding comfort and energy efficiency and are therefore not used today. LÄS MER

  5. 39. Smart and Sustainable Off-grid Housing Powered by Vehicle to Anything (V2X) : An exploratory study to understand the innovation readiness and feasibility for off-grid living powered by Vehicle to Anything (V2X)

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

    Författare :Hanna Borgefeldt; Emma Svensson; [2022]
    Nyckelord :Off-grid; Vehicle to home; V2H; Vehicle to load; V2L; sustainable power generation; renewable energy; technology readiness level; electric vehicle innovation; Off-grid; Vehicle to home; V2H; Vehicle to load; V2L; hållbar kraftproduktion; förnybar energi; tekniksmognadsgrad; innovation; elbilar;

    Sammanfattning : For the EU to reach net-zero by 2050, an increased rate of renewable energy generation is needed. Off-grid tiny houses serve as a sustainable housing option as they are energy conservative, and their primary source of energy is renewable energy. LÄS MER

  7. 40. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

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

    Författare :Abdullah Albalali; [2022]
    Nyckelord :energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

    Sammanfattning : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).
