Wind Power Integration in Québec

Impact on system management

The operating tools and work process are already well adapted to the relatively high uncertainty of the internal load and short term market demand

The integration of the wind generation forecast will be completed this spring

Research projects will help to anticipate the impact of high rate of wind integration

Wind Power Integration in Québec

Challenges

System security must be maintained

The constraint related to the wind generation integration should be minimized

Good forecast will add value to the wind generation
