Flexibility chart: Evaluation on diversity of flexibility in various areas
Yasuda, Yoh; Ardal, Atle Rygg; Carlini, Enrico M.; Estanqueiro, Ana; Flynn, Damian; Gomez-Lázaro, E.; Holttinen, Hannele; Kiviluoma, J.This paper evaluates various aspects of flexibility in power systems worldwide within the multi-country study framework of IEA Wind Task 25, including grid components and actions which have been favoured for enhancing flexibility in different areas/countries/regions, and how TSOs/ISOs/ utilities intend to manage variable generation in their operating strategies. One methodology to evaluate the diversity of flex...
Summary of experiences and studies for wind integration: IEA Wind Task 25
Holttinen, Hannele; Robitaille, André; Orths, Antje; Pineda, Ivan; Lange, Bernhard; Carlini, Enrico M.; O’Malley, Mark; Dillon, Jody; Tande, John OlavIEA WIND R&D Task 25 on “Design and Operation of Power Systems with Large Amounts of Wind Power” collects and shares information on wind generation impacts on power systems, with analyses and guidelines on methodologies. This paper summarizes the main results from the report published on January 2013 describing experience of wind integration as well as the most relevant wind power grid integration studies in th...
Wind and solar curtailment
Lew, Debra; Bird, Lori; Milligan, Michael; Speer, Bethany; Wang, Xi; Carlini, Enrico M.; Estanqueiro, Ana; Flynn, Damian; Gomez-Lázaro, E.High penetrations of wind and solar generation on power systems are resulting in increasing curtailment. Wind and solar integration studies predict increased curtailment as penetration levels grow. This paper examines experiences with curtailment on bulk power systems internationally. It discusses how much curtailment is occurring, how it is occurring, why it is occurring, and what is being done to reduce curta...
Transmission planning for wind energy in the United States and Europe: status a...
Smith, J. Charles; Osborn, D.; Zavaldi, R.; Lasher, W.; Gomez-Lázaro, E.; Estanqueiro, Ana; Trotscher, Thomas; Tande, J.; Korpas, M.; Van Hulle, FransThis paper provides an overview ofmajor transmission planning activities related to wind integration studies in the United States and Europe. Transmission planning for energy resources is different from planning for capacity resources. Those differences are explained, and illustrated with examples from several regions of the United States and Europe. Transmission planning for wind is becoming an iterative proce...
Currents of Changes
Holttinen, Hannele; Orths, Antje; Eriksen, Peter B.; Hidalgo, Jorge; Estanqueiro, Ana; Groome, Frank; Coughlan, Yvonne; Neumann, HendrikThe Power Systems in Denmark, Portugal, Spain, Ireland, and Germany have some of the highest wind penetrations in the world, as shown in Table 1. The management of the different power systems to date,with increasing amounts of wind energy, has been successful.There have been no reported incidents in which wind has directly or indirectly been a major factor causing operational problems on the system. In some are...
Impacts of large amounts of wind power on design and operation of power systems...
Holttinen, Hannele; Meibom, Peter; Orths, Antje; Lange, Bernhard; O'Malley, Mark; Tande, John O.; Estanqueiro, Ana; Gomez, Emilio; Soder, LennartThere are dozens of studies made and ongoing related to wind integration. However, the results are not easy to compare. IEA WIND R&D Task 25 on ‘Design and Operation of Power Systems with Large Amounts of Wind Power’ collects and shares information on wind generation impacts on power systems, with analyses and guidelines on methodologies. In the state-of-the-art report (October, 2007), and the fi nal report o...
Design and operation of power systems with large amounts of wind power : Final ...
Holttinen, Hannele; Meibom, Peter; Orths, Antje; Van Hulle, Frans; Lange, Bernhard; O'Malley, Mark; Smith, J. Charles; Estanqueiro, Ana; Ricardo, JoãoThere are already several power systems coping with large amounts of wind power. High penetration of wind power has impacts that have to be managed through proper plant interconnection, integration, transmission planning, and system and market operations. This report is a summary of case studies addressing concerns about the impact of wind power s variability and uncertainty on power system reliability and cost...

Holttinen, Hannele; Meibom, Peter; Orths, Antje; O'Malley, Mark; Ummels, Bart C.; Tande, John O.; Estanqueiro, Ana; Gomez, Emilio; Smith, J. CharlesThere are a multitude of studies made and ongoing related to cost of wind integration. However, the results are not easy to compare. An international forum for exchange of knowledge of power system impacts of wind power has been formed under the IEA Implementing Agreement on Wind Energy. IEA WIND R&D Task 25 on "Design and Operation of Power Systems with Large Amounts of Wind Power" has produced a state-of-the-...

Holttinen, Hannele; Lemstrom, Bettina; Meibom, Peter; Bindner, Henrik; Orths, Antje; Van Hulle, Frans; Ensslin, Cornel; Tiedemann, AlbrechtHigh penetration of wind power has impacts that have to be managed through proper plant interconnection, integration, transmission planning, and system and market operations. This report is a summary of case studies addressing concerns about the impact of wind powers variability and uncertainty on power system reliability and costs. The case studies summarized in this report are not easy to compare due to diffe...

Holttinen, Hannele; Meibom, Peter; Orths, Antje; Hulle, Frans van; Ensslin, Cornel; Hofmann, Lutz; McCann, John; Pierik, Jan; Tande, John O.An international forum exchange of knowledge of power systems impacts of wind power has been formed under the IEA Implementing Agreement on Wind Energy. The task 'Design and Operation of Power Systems with Large Amounts of Wind Power Production' will analyse existing case studies from different power systems. There is a multitude of studies made and ongoing related to cost of wind integration. However, the resu...
