  1. 1. Energilager i Luleå Energis elnät

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johanna Helmvall; [2019]
    Nyckelord :Energilager; batterilager; solceller; förnybar energi; effektbrist;

    Sammanfattning : This thesis will investigate possible energy storages in Luleå Energi’s power grid within a five-year period. The transition to a more sustainable and efficient energy system, in response to climate change, creates new challenges for the power grid. LÄS MER

  2. 2. Optimering av last och produktion i Gävles fjärrvärmenät : Reducering av effekttoppar via värmelagring i byggnader

    Kandidat-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Fredrik Elofsson; [2019]
    Nyckelord :District heating; load management; peak shaving; heat load reduction; thermal storage; smart energy system; Fjärrvärme; laststyrning; effekttoppar; värmelagring; smarta energisystem;

    Sammanfattning : District heating is today the most common way of providing a building with heat and hot water in Sweden. It is an environmentally friendly product mostly used with renewable fuel. However, at power peaks most companies use production units that are more expensive and worse for the environment and should therefore be avoided as much as possible. LÄS MER

  3. 3. Making grid capacity available through heat pump control

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Karin Arding; Siri In de Betou; [2019]
    Nyckelord :Grid; capacity; electricity; Uppsala; IKEA; peak shaving; electric bus; bus depot; lumped capacity model; Region Uppsala;

    Sammanfattning : In this report the problem of constructing a bus depot with electrical buses despite the lack of grid capacity, was analyzed. A potential solution is investigated, namely smart control of heat pumps in industries. LÄS MER

  4. 4. A package deal for the future: Vehicle-to-Grid combined with Mobility as a Service

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Amanda Bränström; Jonna Söderberg; [2019]
    Nyckelord :energy systems; Vehicle-to-Grid; V2G; Mobility as a Service; power grid; integrated systems; capacity deficiency; peak shaving; electric vehicle; EV; self-driving;

    Sammanfattning : The aim of this report is to evaluate how a future commercially owned fleet of self-driving electric vehicles (EV:s) would be able to provide power in order to avoid power exceedances in the power grid. Exceedances occur when network agreements between grid operating companies are exceeded. LÄS MER

  5. 5. Conservation Voltage Reduction i Sverige - en simuleringsstudie

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Kewin Erichsen; Stefan Viklund; [2019]
    Nyckelord :Conservation Voltage Reduction; Distribution grid; Energy conservation; Load modelling; OpenDSS; Peak shaving; Simulation; Voltage regulation; Technology and Engineering;

    Sammanfattning : Conservation Voltage Reduction, or short just CVR, is a technique in which the reference voltage at a substation is lowered a few percent in order to conserve energy and decrease peak demand in an electrical distribution grid. Thus, CVR can be used when the energy or power capacity can't be satisfied by the feeding grid. LÄS MER
