  1. 1. A Model-Predictive-Control Based Smart-Grid Aggregator

    University essay from KTH/Optimeringslära och systemteori

    Author : Amanda Paulus; [2018]
    Keywords : ;

    Abstract : Intermittent energy source usage, such as solar and wind power, is continuously increasing. Intermittent energy sources are highly dependent on prevailing weather conditions, resulting in stochastic electricity generation. The expected stochasticity in electricity generation will cause issues for the current power grid. READ MORE

  2. 2. Reactive power management capabilities of Swedish sub-transmission and medium voltage level grid

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

    Author : Michal Tomaszewski; [2018]
    Keywords : electric power systems; reactive power; sub-transmission level grids; PSS E; power ow analysis; wind farms; smart grids; droop control; elektriska system; reaktiv eekt; mellan spanningsnivan; PSS E; strom odesanalys; vindkraftparker; smarta nat; droop control;

    Abstract : Rising penetration of renewable energy sources in electric power grids isboth a challenge and an opportunity to optimally utilize the potential of eitherwind or PV energy sources, to stabilize operation of future power systems.Bi-directional ows between distribution and transmission system operatorscause signicant problems with keeping the voltages in the grid within admissiblelimits.

    Keywords : European Energy Market; German Energy Market; United Kingdom Energy Market; European Energy Strategy; Smart Grids; Low Temperature District Heating and Cooling;

    Abstract : It is known that the heating and cooling market constitutes a large part of energy market across Europe and that the domestic and non-domestic buildings have together the largest share of energy demand. The aim of the European climate goals is to reduce the use of fossil fuel based systems and the allowance of energy demand. READ MORE

  5. 5. The Swedish energy system and the role of hydrogen : a modelling study of the energy and transport sector

    University essay from KTH/Energi och klimatstudier, ECS

    Author : Adrian Lefvert; [2018]
    Keywords : ;

    Abstract : In light of the ongoing climate change dilemma, and the consequences that a failure to reduce the greenhouse gas emissions to a stable level will most likely induce, there is an overwhelming consensus among scientists and political leaders that actions are necessary to ensure that adaptation and mitigation options are secured. The European Union, as well as the Swedish government, agrees with the Intergovernmental Panel on Climate Change and the United Nations Conference of Parties that a reduction of the fossil fuel dependency is essential.
