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 fifth term (2018-2020). 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 Generation in 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:
- Impacts of variability and uncertainty on cycling losses of generators, balancing and reserve requirements.
- Capacity value of wind power
- Efficient use of existing transmission capacity and requirements for new network investments
- System stability issues
