Grid connectivity does not mean only the physical linking with the state transmission system, but has to fulfill the operational and commercial needs of a power system.

Electricity generation from wind energy is characterised by significant daily and seasonal fluctuations, which is presently being forecasted with a limited certainty only. This gives rise to challenges for interconnection of wind energy system with the grid in regard to system safety security and reliability of electricity supply.

Energy policies are in transition worldwide based on a convergence of factors including static oil production coupled with increased demand, a desire for energy independence, and growing awareness of climate change.
