Welcome to Task 25 Homepage
Task 25 of the IEA Wind Implementing Agreement was approved at ExCo 56 in September 2005. The current term continues through 2011. An extension will be proposed in October 2011 to run through 2014.
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 will be updated through 2011 as a final report of the current term. The task will end with developing guidelines on the recommended methodologies when estimating the system impacts and the costs of wind power integration. Also best practice recommendations will be formulated on system operation practices and planning methodologies for high wind penetration.
