  3. 2. Estimating CO2 reductions from renewable energy sources : The impact of power system nonlinearities

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

    Author : Kristoffer Berglund; [2022]
    Keywords : CO2 reduction; Dispatch model; Econometric model; Unit commitment; CO2-reduktion; ekonometriska modeller; produktionssimuleringsmodeller;

    Abstract : Replacing conventional generation with renewable generation in power systems is essential for reducing CO2 emissions. It is important to know how effective renewables are in reducing CO2 emissions. Since CO2 reduction cannot be measured directly, different methods have been used to estimate reduction of CO2 emissions. READ MORE
