  1. 11. Implementation of Wind- and Hydropower in Electrical Grids in Dalarna

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

    Author : Ebba Hellstenius; Nils Johansson; [2020]
    Keywords : Electrical grids; Hydropower; Power system; Transmission lines; Voltage regulation; Wind power;

    Abstract : These days more renewable energy sources are beingintegrated into the power system, while nuclear power and otherconventional energy sources are being demounted. This comeswith some obstacles, e.g. the renewable energy sources do nothave the same ability to produce reactive power as conventionalenergy sources do. READ MORE

  3. 12. Operation of battery energy storage system for frequency control of hydropower operated in island mode

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Amanda Hallblad; [2020]
    Keywords : Battery energy storage system BESS ; hydropower; microgrid MG ; operational strategies; frequency control; PowerFactory;

    Abstract : The purpose of this study is to analyse how a battery energy storage system (BESS) can support the frequency and voltage stability for an islanded microgrid containing a hydropower plant. Two different microgrids, both situated in Sweden, are evaluated. Modelling and dynamic simulations are conducted in the PowerFactory tool. READ MORE
