摘　　要：调峰电源的配置可优化直流送电曲线,减少送端电源弃电,但过度配置调峰电源将增加建设成本。通过建立送端电源基地整体出力数学模型,计算送端电源逐月典型日出力的直流送电曲线,并以受端电网新能源消纳指标和整年的直流送电量为约束,不断调整送端调峰电源配置规模以满足预期目标,实现送端调峰电源合理优化配置,为新型电力系统下大规模直流输电送端电源配置提供了科学依据。The allocation of peaking power sources can optimise DC power delivery curve and reduce power dumping of supply side,but excessive peaking power capacity will increase construction cost.This study established a mathematical model of the overall power output of supply side and calculated the DC power curve of typical daily power output at the supply side month by month.By taking consumption/absorption of new energy generation at receiving side and yearly DC power output as the constraints,the scale of peaking power allocation at supply side was adjusted repeatedly to satisfy the constraints and achieve rational and optimal allocation of supply side peaking power sources.This method provides a scientific basis for allocation of supply side sources with respect to large-scale DC transmission.
