低碳发电调度与节能发电调度的一致性评估

Consistency Evaluation of Low-carbon Generation Dispatching and Energy-saving Generation Dispatching

"十二五"期间,CO2排放量将成为全社会节能减排的硬性指标。作为节能减排的主要行业,电力行业已经实施节能发电调度(energy-saving generation dispatching,ESGD),而低碳电力调度(low-carbon generation dispatching,LCGD)将是未来的发展方向之一。提出了对LCGD与ESGD一致性的评估方法,从解的一致性和目标函数的一致性2个角度定义了评估指标,分析了LCGD与ESGD一致的条件,分析表明调度结果存在差异主要是由于碳捕集电厂(carboncapture power plant,CCPP)和燃油/气电厂(oil/gas powerplant,OPP/GPP)的存在。算例表明该方法可以有效进行评估,LCGD和ESGD的一致性较高,若CCPP的比重加大则一致性降低。该结果可以为ESGD管理办法的完善、节能目标与低碳目标的协调调度提供支持。

During ＂Twelfth Five-Year＂ period,CO2 emission will become the binding targets of energy saving and emission reduction in China.As a major energy saving industry,power industry has implemented energy-saving generation dispatching（ESGD）,and low-carbon generation dispatching（LCGD） will be one of the future development directions.Consistency evaluation method of LCGD and ESGD was proposed in this paper.Evaluation indexes were defined from the angles of both solution consistency and objective function consistency.Consistent condition of LCGD and ESGD was analyzed.The analysis reveals that reasons for the dispatching differences are the existences of carbon capture power plants（CCPP） and oil/gas power plants（OPP/GPP）.The example shows that the consistency evaluation method is effective.The consistency of LCGD and ESGD is relatively high,and will be lower when there are more CCPPs.The result provides support for the improvement of measures for ESGD and the coordination of ESGD and LCGD.
