摘要:

电力工业节能减排是国家“十二五”能源发展战略的重要目标,也是新一轮电改中放开发用电计划必须兼顾的关键因素,进一步挖掘电力生产全过程节能潜力是未来电网面临的挑战性课题。本文针对某区域电网交直流并联运行的特有方式,提出以日内滚动的跨省交易实现高、低能耗能源互补,以交直流潮流优化分配实现输电运行经济性最优,最终实现日内滚动节能调度的发输全过程优化。为了适应大电网快速优化决策的需要,本文进一步设计了发输电联合迭代优化计算流程,并对日内滚动节能调度的经济、节能效益进行了测算,揭示了实施发输电联合优化的日内滚动节能调度的巨大效益空间。

Energy-saving in electricity industry is regarded as one of important strategic targets in “Twelfth Five-Year Plan” for energy. And it is the key issue for deregulation of generation schedule in revo-lution of power market. CSG is facing a challenging topic of mining potential for the whole process of real electric energy production. The intraday rolling optimization strategy under the circumstance of AC/DC hybrid operation mode of regional grid is discussed. This paper proposed a new strategy about high energy-consumption and clean energy replacement as well as optimizing transmission distribution in AC/DC channels. A Joint iterative optimization process was proposed to solute generation and transmission models with a target of minimizing real-time energy consumption increment. The assessment of economic benefits and energy-saving profit based on practical data proved huge potential of intraday rolling energy-saving scheduling using joint optimization of generation and transmission.
