  1. 6. Collective PV nano-grid for households in Linga Linga : A Minor Field Study in Mozambique

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

    Författare :Wilma Diaz Hjelm; Ellie Olsson; [2022]
    Nyckelord :Collective Energy System; Solar PV system; Electricity Accesses; off-grid; nano-grid; Rural Mozambique; Minor Field Study; Project Vita; Kollektivt Energisystem; Solcellssystem; Tillgång till Elektricitet; Nano-Nät; Moçambiques Landsbygd; Minor Field Study; Project Vita;

    Sammanfattning : About a third of Mozambique’s population has access to electricity, and the same number in rural areas, where most of the population lives, is down to 5 %. Small-sized off-grid solutions are economical alternatives to increase the electricity access rate in rural areas, and solar power is a common energy source due to price and weather conditions.

  3. 7. EV Fleet Flexibility Estimation on the Distribution Network

    Master-uppsats, KTH/Energiteknik

    Författare :Bilal Fares; [2020]
    Nyckelord :;

    Sammanfattning : A new electricity market model was drafted in Denmark (1) to define the roles of different players and promote the integration of renewable generation as well as the gradual shift towards smartgrids. Along with a clear political will and adjustments of some regulatory barriers, this potentiallyopens the market for an increased share in electric vehicles (EVs). LÄS MER

  4. 8. Resynchronisation of Islanded Power Systems

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

    Författare :Emelie Frost; [2020]
    Nyckelord :;

    Sammanfattning : The electricity demand and need of renewably produced electricity has increased the interest in locally produced electricity, also called distributed generation. The increase of distributed generation increases the risk of islanding, a state when a part of the grid has been electrically isolated. LÄS MER

  5. 9. Techno-economic analysis of demand flexibility from heat pumps for multi-family buildings in Sweden based on two case studies

    Master-uppsats, KTH/Energiteknik

    Författare :Hsin-Ting Ko; [2020]
    Nyckelord :Demand flexibility; Heat pump; IDA ICE; Smart grid; Thermal comfort; Thermal inertia; Bottom-up simuleringsmodell; efterfrågeflexibilitet; Demand response; energiteknologi; slutanvändarbeteende; grön byggnad; VVS-systemkontroll; värmepump; IDA ICE; smart nät; termisk komfort; termisk tröghet;

    Sammanfattning : Sweden is undergoing energy transition to become a zero-carbon economy with electricity production aims at 100% from renewable resources by 2040. Sweden also has a national goal to have fossil-free vehicle fleet by 2030. The increasing share of intermittent renewable resources creates growth in mismatches between electricity supply and demand.

  7. 10. Modelling the European High-voltage electricity transmission

    Master-uppsats, KTH/Energiteknik

    Författare :Piotr Jędrzejewski; [2020]
    Nyckelord :;

    Sammanfattning : This Master’s thesis describes modelling of the cross-border electricity transmission network of Europe. Under this work an extension of The Open Source Energy Model Base for the European Union (OSeMBE) was developed, implementing interconnections to the already existing model. LÄS MER
