1.641.631.621.611.60In this model, the scheduled wind power output is considered as an optimization variable and two risk reserve constraints are considered to satisfy technical requirements for safe and reliable operation of power systems. The costs of up and down spinning reserve that can compensate the overestimation and underestimation of wind power generation are also
