  1. 1. Short-term planning and operational profitability of multi-ESS hybrid wind farms

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

    Författare :Javier Ortega Paredes; [2022]
    Nyckelord :Energy storage systems; day-ahead market; wind power; stochastic short-term planning problem; hybrid wind farm; Energilagringssystem; day-ahead-marknad; vindkraft; stokastiskt kortsiktigt planeringsproblem; hybridvindkraftverk.;

    Sammanfattning : The unpredictability and variability of wind power generation can pose an economical risk to the wind power producer when participating in the day-ahead market and delivering the committed generation. These risks come from the creation of imbalances due to a mismatch between the sold and real generation fed to the grid. LÄS MER

  3. 2. Open Source Grid Expansion Models for the EU Project Spine

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

    Författare :Akshaya Tammanur Ravi; [2021]
    Nyckelord :Expansion Planning; Renewable Energy Sources; Operational Variability; Representative Days; Long-term Uncertainties; Stochastic Optimization; Utbyggnadsplanering; Förnybara energikällor; Variabel driftsituation; Representativa dagar; Långsiktiga osäkerheter; Stokastisk optimering;

    Sammanfattning : Modern power systems are at the forefront of addressing the transition towards a decarbonized energy system, with increased integration of renewable energy sources becoming the key means to achieve the same. In this context, an expansion planning problem provides a decision support framework for investments in new generation and transmission assets over a long time-frame, addressing a wide range of technical and economic criteria aligned with national policies.

  4. 3. On stochastic unit commitment for thermal power plants

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

    Författare :Elin Rahmqvist; [2020]
    Nyckelord :;

    Sammanfattning : Climate change is a fact, a crisis threatening every country, economy and human. Toprevent this crisis, the emission of greenhouse gases needs to decrease dramatically. 72%of global greenhouse gas emissions in 2016 came from energy production where electricityand heat account for 42% of the 72%.

  5. 4. Reliability-Constrained Microgrid Design

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Jesús Paniagua Sánchez-Mateos; [2016]
    Nyckelord :Microgrid planning; Microgrid investment; Uncertainty; Optimization problem; Bender’s decomposition; Distributed energy resources; Islanded operation; Reliability importance index.;

    Sammanfattning : Microgrids are new challenging power systems under development. This report presents a feasibility study of microgrid development. This is an essential task before implementing microgrid systems. LÄS MER

  7. 5. Robust Production Planning for District Heating Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Jonatan Rantzer; [2015]
    Nyckelord :production planning; unit commitment; district heating; stochastic programming; optimization; robust; MPC; startup; shutdown; Mathematics and Statistics; Technology and Engineering;

    Sammanfattning : Efficient use of energy becomes increasingly important in the modern society, with climate change as a driving factor. Short term production planning for district heating networks is motivated by a customer demand that varies according to a daily cycle, but which is directly dependent on changes in temperature and customer behaviour.
