摘　　要：随着“双碳”目标的不断推进,未来电网中可再生能源比例会越来越高,常规基地送电方式已无法适应受端电网的需求。针对这一情况,该文提出了一种综合计及受端电网可信和调峰需求的风光储基地中长期运行方式优化方法。在可信容量供应方面,该方法综合考虑了全年负荷尖峰时段和每日净负荷最高时段的可信电能供应,并在基地送电中加强了上述两方面的供电能力。在参与受端电网调峰方面,该方法提出了送受风光共用消纳空间的理念,并使用基地储能将基地风光出力转化至受端电网调峰压力最小的时段。算例结果表明,所提出的方法显著提高了大型风光储基地的各项送电收益并降低了弃电量。验证了所提出的模型最大程度地发挥了基地储能在保供和调峰方面的作用,提供了更适用于受端电网可信和调峰需求的基地送电曲线。As the"dual carbons"(namely,carbon peak and carbon neutrality)goal progresses,the proportion of renewable energy in power grids is expected to increase significantly.Consequently,conventional transmission methods of bases will no longer meet the requirements of receiving grids.To address this issue,a medium-and long-term optimization method for wind/solar/storage bases has been proposed,considering both credible capacity and peak shaving demands of receiv-ing power grids.Regarding credible capacity supply,this method comprehensively considers the credible power supply during annual peak load periods and daily highest net load periods.The power supply capacity of the base is strengthened in these two aspects within base transmission.For participating in the peak shaving of receiving power grids,this method introduces the concept of shared absorption space between wind/solar from both bases and receiving power grids.Base energy storage is utilized to convert wind and solar power output to periods when peak shaving pressure on receiving power grids is minimized.The calculation results demonstrate that the proposed method is adopted to significantly en-hance various transmission benefits for large-scale wind/solar/storage bases and reduce the abandoned power.The proposed model has been validated to maximize the role of base energy storage in ensuring supply reliability and peak shaving needs,thus providing a more suitable base transmission curve for these requirements.
