  1. 1. On The Evaluation of District Heating Load Predictions

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Herman Hansson; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : District Heating is a technology with the potential to enable a fossil-free society. However, to realize this potential, some improvements need to be made in order to improve District Heating operation at large, decrease losses in the systems, and thus increase the competitiveness of District Heating as a technology.

  2. 2. Utvärdering av lastprognoser : En undersökning om lastprognoserna skapade till flexibilitetsmarknaden CoordiNet i Uppsala

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Emma Wiss; [2023]
    Nyckelord :Lastprognoser; Flexibilitetsmarknader; Kapacitetsbrist; Uppsala; Felkällor;

    Sammanfattning : The aim of the thesis was to evaluate the load forecasts used in the flexibility market CoordiNet, more specific the load forecasted used for Uppsala during the winters 2020-2021 and 2021-2022. The load forecasts are based on machine learning and to answer the aim of the thesis the following three research questions have been studied: what factors affect the load forecasting errors, which factors are important to increase the reliability of the load forecasts and how can Vattenfall Eldistribution evaluate load forecasts in the future.

  3. 3. Machine Learning in Electricity Load Forecasting of Prosumer Buildings

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

    Författare :Lu Zhao; [2021]
    Nyckelord :;

    Sammanfattning : Short-term load forecasting plays a key role in energy optimizations such as peaking shaving and cost arbitrage. Forecasting the aggregated load of a city or region has been researched for years and produced accurate results with time lead ranging from an hour to a week. LÄS MER

  4. 4. Opportunities, Barriers and Preconditions for Battery Energy Storage in Sweden : A Study Investigating the Possibilities of Grid Connected Lithium-Ion Battery Energy Storage Systems in the Swedish Electricity Market

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

    Författare :Maja Isaksson; Ellen Stjerngren; [2019]
    Nyckelord :Energy storage; Battery energy storage system; Lithium-ion batteries; Stationary applications; Grid flexibility; Electricity market; Regulatory framework;

    Sammanfattning : The global energy system is under transformation. The energy transition from a centralized, fossil fuel based energy system to a more decentralized, renewable energy based system will challenge the balancing of electricity supply and demand. This stresses the importance of grid flexibility. LÄS MER

  5. 5. Short-Term Heat Load Forecasting in District Heating Systems : A Comparative Study of Various Forecasting Methods

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

    Författare :Zacharias Poutiainen; [2019]
    Nyckelord :;

    Sammanfattning : Short term heat load forecasts are vital for optimal production planning and commitment of generation units. The generation utility also bares a balance responsibility toward the electricity market as a result of CHP generation. Sub-optimal load forecasts can lead to high costs relating to unit commitment, fuel usage and balancing costs. LÄS MER
