IEA Wind Task 25

Design and Operation of Energy Systems with Large Amounts of Variable Generation
Services

About Task 25

The ultimate objective of Task 25 is to provide information to facilitate the highest economically feasible wind energy penetration within electricity power systems worldwide. This task supports this goal by analyzing and further developing the methodology to assess the impact of wind power on power systems

Task 25 analyzes and develops methodologies that assess the impact of variable generation on power and energy systems. This information facilitates economically feasible wind energy penetration in electricity systems worldwide. Task 25 summarizes results from participating countries and formulates best practice recommendations for system impact and integration studies.

Task 25 started in 2006 and is now in its sixth term (2021-2024). As the work has evolved from wind integration studies to cover both wind and solar energy, and both electricity and energy systems, the name of Task 25 was changed from Design and Operation of Power Systems with Large Amounts of Wind Power to Design and Operation of Energy Systems with Large Amounts of Variable Generationin 2018.

The international forum has been formed or exchange of experience gained and studies conducted. The case studies address different aspects of power system operation and design:

  1. Impacts of variability and uncertainty on cycling losses of generators, balancing and reserve requirements
  2. Capacity value of wind power
  3. Efficient use of existing transmission capacity and requirements for new network investments
  4. System stability issues

Who can participate in Task 25?

For the 2018-20 phase, 16 member countries and 2 sponsors are involved in Task 25. Most countries have participation of their TSOs (Transmission System Operator) either following their national project or participating directly to the Task 25 meetings.

To participate in the research activities of Task 25, researchers must reside in a country that participates in the IEA Wind Agreement AND has agreed by official letter to participate in Task 25.

To join a task, a member country of the IEA Wind TCP designates a lead institution that agrees to the obligations of task participation (pay the annual fee and agree to perform specified parts of the work plan).

Researchers active (performing part of the work plan) benefit from meetings and professional exchange during the term of the task. Countries participating in the task benefit from the information developed by the task.

Participants can gain access to the Members Only portion of the website by receiving the username and password from the Operating Agent, Niina Helistö.
