Welcome to Task 25 Homepage
The current term continues through 2017 and this is the fourth 3-year-phase for the Task work.
The ultimate objective is to provide information to facilitate the highest economically feasible wind energy penetration within electricity power systems worldwide. This task supports this goal by analysing and further developing the methodology to assess the impact of wind power on power systems. The Task has established an international forum for exchange of knowledge and experiences related to power system operation with large amounts of wind power. The challenge is to create coherence between parallel activities with Transmission System Operators and other research and development work worldwide.
The participants collect and share information on the experience gained and the studies conducted up to and during the task. The case studies address different aspects of power system operation and design: reserve requirements, balancing and generation efficiency, capacity credit of wind power, efficient use of existing transmission capacity and requirements for new network investments, bottlenecks, cross-border trade and system stability issues. The main emphasis is on the technical operation. Costs are assessed when necessary as a basis for comparison. Also technology that supports enhanced penetration are being addressed: wind farm controls and operating procedures; dynamic line ratings; storage; demand side management (DSM), etc.
The task work began with a state-of-the-art report that collected the knowledge and results through 2008. This report was updated in 2013 as a final report of the second phase, and will see an update in 2015 for the third phase. The task developed guidelines on the recommended methodologies when estimating the system impacts and the costs of wind power integration: Recommended Practices 16 of IEA Wind.
