  1. 1. Analysis of Prerequisites for Connection of a Large-Scale Photovoltaic System to the Electric Power Grid

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fanny Lilja; [2021]
    Keywords : solar energy; large-scale photovoltaic system; PV; Swedish power system; power output fluctuations; voltage quality; voltage variations; reactive power compensation; PSS E; solenergi; storskalig solcellsanläggning; PV; Sveriges kraftsystem; effekförändringar; spänningskvalitet; spänningsvariationer; reaktiv effektkompensering; PSS E;

    Abstract : The deployment of large-scale photovoltaic (PV) systems is rising in the Swedish power system, both in quantity and in system size. However, the intermittent characteristics of the PV production raises questions concerning the stability in the electric power grid, and power output fluctuations from the PV systems can lead to voltage quality issues.

  2. 2. Power Plant Operation Optimization Economic dispatch of combined cycle power plants

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Stefano Rosso; [2019]
    Keywords : ;

    Abstract : As electricity production from renewable sources increases, higher flexibility is required by fossil fuel generation to cope with the inherent fluctuations of solar and wind power. This results in shorter operating cycles and steeper ramps for the turbines, and more uncertainty for the operators. READ MORE

  3. 3. Battery energy storage design and operation in an HVDC-system with WPP clusters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Harald Åkesson; [2019]
    Keywords : BESS; Energy storage; State of charge; Windpower; HVDC; Technology and Engineering;

    Abstract : The electricity sector is in the beginning of a large shift from centralized dispatchable production to distributed variable production. With this necessary change, new challenges arise. One crucial challenge is related to upholding the system balance in the power grid. READ MORE

  4. 4. Integration of thermochemical heat storage with a municipal district heating system : In future scenario with large variations in electricity price

    University essay from Mälardalens högskola/Framtidens energi; Mälardalens högskola/Framtidens energi

    Author : Mehdi Farahmand Ghaffarpour; Henrik Ros; [2018]
    Keywords : CHP; Operation strategies; Energy Storage; Thermochemical Heat Storage; THS; Techno Economic; Optimization; District Heating; Merit order effect;

    Abstract : This thesis investigates the feasibility and benefits of integrating Thermochemical heat Storage (THS) into a CHP (Combined Heat and Power) plant. A case study is done for the CHP-plant in Sala, Sweden, with a maximum heat output of 20.9 MW and maximum electricity output of 9.6 MW. READ MORE

  5. 5. Market Role, Profitability, and Competitive Features of Combined Heat and Power Plants in the Swedish Future Electricity Market with High Renewable Integration

    University essay from KTH/Kraft- och värmeteknologi

    Author : Jimmy Fransson; [2017]
    Keywords : ;

    Abstract : The Swedish energy market is currently undergoing a transition away from fossil fuels to renewable energy sources, including a potential phase-out of nuclear power. The combination of a phase-out with the expansion of intermittent renewable energy leads to the issue of increased fluctuations in electricity production. READ MORE
