Abstract: To improve the comprehensive benefits of regional power grid after the consumption capacity of wind power accommodation, and use the existing trading rules of electric peak regulation ancillary services, this paper established a comprehensive evaluation index of regional power grid comprehensive benefits based on entropy weight method. Considering the uncertainty of wind power and the peak-shaving auxiliary services, the comprehensive benefits evaluation model of regional power grid was established based on the holistic model method. The correctness of the proposed model was verified by simulation. The results showed that the scheme with electrode type electric boiler on the power supply side could improve the wind power consumption capacity of regional power grid compared with the alternative scheme. At the same time, it provided enough flexibility for system and effectively improved the comprehensive benefits of the power side of regional power grid.

Key words: wind power accommodation, comprehensive benefit, peak regulation ancillary service, entropy weight method, holistic model method
