Discussion on Large-scale Wind Power Integration in the Context of Smart Grid

Fluctuation of wind power may be superposed to power grid after its integration,which changes the dispatch target of total load of system into net load with output power of wind power excluded.Certainty of wind power capacity changes easily and it may have influence on planned standby capacity.Therefore,the paper analyzes probability of shutdown of all wind power units and it points out that when the integrated wind farm ranges far and wide,the rate of power setback may slow down sharply,which is good for balance in the dispatch.The experience in operation indicates that integration of wind power needs no extra auxiliary power plants and storage system.
