摘要
为了研究提升地区电网风电消纳能力后的综合效益情况,兼顾现行的电力调峰辅助服务交易规则,建立基于熵权法的地区电网综合效益的综合评价指标。综合考虑风电功率的不确定性和有偿调峰辅助服务费用等因素,基于整体模型法建立地区电网综合效益的评估模型。采用算例试验对所提模型进行仿真验证,算例结果分析表明,电源侧配置电极式电锅炉方案相较于替代方案可以提高地区电网风电消纳能力,为系统提供充足的灵活性,能够有效提升地区电网电源侧综合效益。
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.
