摘　　要：在中国提高新能源并网率、助力“碳达峰、碳中和”目标的背景下,实现电力资源的跨区域配置,有利于发挥不同区域间的资源互补效益,提高互联电网的整体新能源消纳能力。针对当前出清方法难以实现跨区备用辅助服务资源配置的难题,提出了一种联合考虑电能量与备用辅助服务的联络线可行域构建方法,并提出了计及跨区备用辅助服务互济的互联电网协同市场出清模型。通过在联络线可行域中考虑跨区备用辅助服务互济约束,完整刻画电能量-备用辅助服务交易空间,并通过互联电网协同出清实现备用跨区配置。基于某区域互联电网算例表明,所提方法可成功实现跨区备用资源的优化配置,进而整体提升互联电网的新能源消纳能力与综合运行效益。To achieve the targets of carbon peak and carbon neutrality with the increasing utilization of renewables,regional coordinated transaction scheduling has emerged as a promising approach that can deliver complementary economic advantages across regions while promoting renewable energy consumption.However,market clearing of reserve ancillary services sharing between different regions remains a challenging problem.This paper proposes a method for building the tie-line feasible region with joint consideration of power energy and reserve ancillary services,and develops a market clearing model for regional coordinated transaction scheduling with reserve ancillary services sharing.The proposed model explicitly incorporates reserve ancillary services sharing constraints and sculpts the energy-reserve transaction feasible region.Based on the feasible regions,the market clearing method provides for synchronous energy-reserve transactions through tie-line transmission.A case study of an interconnected network demonstrates that the proposed method can achieve reserve ancillary services sharing across different regions,promote renewable energy accommodation,and reduce total operating costs.
