  5. 24. Cross-zonal trading in the continuous intraday market : An agent-based model approach

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

    Författare :Giulia Gamberi; [2021]
    Nyckelord :;

    Sammanfattning : The accelerating growth of variable energy sources in the European market has brought to weather-dependent and less predictable generation profiles, which leads to a shift of the traded volumes from the day-ahead to the continuous intraday market because the latter is important for adjusting final imbalances. The undergoing transformation of the market introduces the need for improved trading solutions, seen already in the growing use of algorithmic trading, and for optimal market design, including the transmission capacity allocation management.
