Wind power as one of the most competitive clean sources of energy will play an i mportant role in China's power sector lowcarbon process. The uncertainty of wi nd power brings about many problems for subsequent power dispatch, so traditiona l power scheduling will no longer be fully applicable. This paper establishes a lowcarbon electricity scheduling model under wind power grid background: to ca lculate total operating cost by considering both economic cost and carbon price quantify environmental cost; to describe the uncertainty of wind power by constr ucting a wind stochastic model; to restrict the gap between planned wind power v alue and the actual value with subjective penalty factor and spare deviation fac tor. In the case study, we firstly discussed the relationship among carbon price , penalty factor, and spare factor and found a positive correlation between carb on price and penalty factor and a negative correlation between carbon price and spare factor. Then by qualifying penalty factor and spare factor with carbon pri ce, subjective investment attitude was quantitatively characterized, and the imp act of different investment approach on scheduling was analyzed. The scheduling policy ultimately obtained can achieve the balance between economy and environme nt, between uncertainty and certainty, between objectivity and subjectivity.
