IEA Wind Task 41: Enabling Wind to Contribute to a Distributed Energy Future (Working period 2019 - 2023)

IEA Wind Task 41 aims to create framework conditions for decentralised small and medium-sized wind turbines in order to establish them as a competitive and reliable technology for decentralised energy generation. A strategic focus in the pursuit of this goal is the revision of the IEC standard for wind turbines, taking into account the latest research results.

Short Description

Task 41 deals with decentralized wind power plants, their technological development and evaluation, the development of cost-saving potentials as well as their integration into future energy systems and markets. The technological spectrum ranges from small wind turbines (from 1 kW) to large wind turbines. The aim of Task 41 is to advance international research in this field in order to enable further technological development and the exploitation of cost-saving potential and, in parallel, to create framework conditions that will enable integration into future energy systems and markets.

Goals and contents

  • Recommendations for the revision of standards
  • Design of a platform for the exchange of measurement data
  • Collection of high-quality data sets as a basis for development
  • Analysis and revision of existing yield forecasting tools
  • Recommendations for the design of standards for the grid connection of wind turbines
  • Development of a tool for planning island and micro grids
  • Development of models for the control of wind turbines in island and micro grids
  • Cooperation with other IEA tasks

Work packages

  • WP0 Management and Coordination
  • WP1 Design Standards for small and mid-sized wind turbines
  • WP2 Data Sharing Portal for DW Research
  • WP3 Accurate performance assessment
  • WP4 Integration of DW into expanding distributed generation marketplace
  • WP5 Outreach and collaboration
  • WP6 Innovation to reduce technology LCOE

Austria can actively contribute to WP1 and WP2 due to extensive knowledge from national research projects as well as practical experience from the Energy Research Park Lichtenegg. Among other things, concrete proposals for the revision of international standards were provided and measurement data was made available for the data exchange platform. Furthermore, thanks to the excellent networking within the European community, collaborations with external stakeholders and further tasks were initiated within WP5, e.g. a conference for decentralized wind energy in Vienna.

Nationally achieved results during the project lifetime:

  • Participation in the Stakeholder Forum for the revision of IEC 61400.
  • Dissemination of relevant national research results within the task meetings
    - SmallWindPower@Home
    - Smalwind4Cities
    - Master thesis
  • Organization of a two-day IEA Task Conference in Vienna
  • Open day in the energy research park Lichtenegg
  • Dissemination of a report on the topic "Decentralized Wind Energy in Austria
  • Creation of an expert and stakeholder network of small wind power producers, operators, and researchers
