      Yasuda, Yoh; Bird, Lori; Carlini, Enrico; Eriksen, Peter Børre; Estanqueiro, Ana; Flynn, Damian; Fraile, Daniel; Gomez Lazaro, Emilio; Martín-Martínez, Sergio; Hayashi, Daisuke; Holttinen, Hannele; Lew, Debra; McCam, John; Menemenlis, Nickie; Miranda, Raul; Orths, Antje; Smith, J. Charles; Taibi, Emanuele; Vrana, Til Kristian (Peer reviewed; Journal article, 2022)
      As the share of VRE (variable renewable energy) has grown rapidly, curtailment issues have arisen worldwide. This paper evaluates and compares curtailment situations in selected countries using an objective and quantitative ...
    • Flexibility chart 2.0: An accessible visual tool to evaluate flexibility resources in power systems 

      Yasuda, Yoh; Carlini, Enrico Maria; Estanqueiro, Ana; Eriksen, Peter Børre; Flynn, Damian; Herre, Lars Finn; Hodge, Bri-Mathias; Holttinen, Hannele; Koivisto, Matti Juhani; Gómez-Lózaro, Emilio; Martínez, Sergio Martín; Menemenlis, Nickie; Morales-España, Germán; Pellinger, Christoph; Ramos, Andrés; Smith, Charlie; Vrana, Til Kristian (Peer reviewed; Journal article, 2023)
      Various aspects of power system flexibility are evaluated within the multi-country study framework of IEA Wind Task 25. Grid components and actions which have been adopted for enhancing flexibility in different areas, ...
    • Improving wind power market value with various aspects of diversification 

      Vrana, Til Kristian; Svendsen, Harald Georg; Korpås, Magnus; Couto, António; Estanqueiro, Ana; Flynn, Damian; Holttinen, Hannele; Härtel, Philipp; Koivisto, Matti; Lantz, Eric; Frew, Bethany (Chapter; Peer reviewed, 2023)
      The wind generation share in many European bidding zones is now large enough to affect the market value of wind power, and wind energy is getting less-than-average market price in day-ahead markets. As alternatives to ...
    • Strategies for Continuous Balancing in Future Power Systems with High Wind and Solar Shares 

      Nordström, Henrik; Söder, Lennart; Flynn, Damian; Matevosyan, Julia; Kiviluoma, Juha; Holttinen, Hannele; Vrana, Til Kristian; van der Welle, Adriaan; Morales-España, Germán; Pudjianto, Danny; Strbac, Goran; Dobschinski, Jan; Estanqueiro, Ana; Algarvio, Hugo; Martinez, Sergio Martin; Lazaro, Emilio Gomez; Hodge, Bri-Mathias (Peer reviewed; Journal article, 2023)
      The use of wind power has grown strongly in recent years and is expected to continue to increase in the coming decades. Solar power is also expected to increase significantly. In a power system, a continuous balance is ...
    • System impact studies for near 100% renewable energy systems dominated by inverter based variable generation
