Abstract Wind power has the features of uncertainty and intermittence.So firstly,the concept of the wind power pre-penetration rate is proposed.Combined with wind power forecast accuracy,the wind power forecast error is presented.Secondly,the model of wind power forecast error growth is established by considering the variability of wind power forecast error over time,and the model of wind power uncertainty (WPU) based on error growth is established.On the basis of the weight interval of schedulable load (WISL),schedulable load (SL),and energy storage system (ESS),the wind cost model is established,and a coordinated optimization dispatch model for wind power integration considering load benefits is established.Finally,the Matlab is used to solve the optimization model.Taking the power system of a certain area as the research object,the results show that the given method can reduce the wind curtailment rate and thermal power reserve capacity.

Key words： Wind power uncertainty output error growth load benefits wind curtailment rate reserve weight interval
