For a highly intermittent power source such as wind, forecasting and scheduling are critical aspects.
When wind provides less than 3% of the total electricity produced in India, this volatility could be acceptable. But when we are looking wind scaling to 50000 MW by 2020 ( from the current 17000 MW), it is imperative to look at robust solutions for forecasting to smoothen grid integration.
The following were some of the interesting web resources I found discussing various aspects of integrating wind power with the grid.

That the variability of wind power isn’t particularly significant when measured over multiple wind farms spread over a large area is good news for India which has the geography to take advantage of this, but that would in turn need a very efficient grid which could be a stumbling block.
