大规模风光储并网碳经济性评估

CARBON ECONOMY EVALUATION OF LARGE-SCALE WIND-SOLAR-STORAGE POWER

构建大规模风光储并网碳经济性评估模型。首先根据储能设备最小年均运行成本及缺电率确定风光储电源容量,在此基础上构建碳排放量评估模型;其次基于生命周期成本理论构建风光储成本评估模型,并结合动态碳交易价格构建碳经济效益评估模型;然后在输送等量电能的前提下分别构建风光储电源外送、火电外送和风光与火电打捆外送3种方案,以评估风光储并网的低碳经济性;最后通过实际算例分析验证评估方法的有效性、合理性。

The assessment of the low-carbon economy of the power system is beneficial to guiding its planning and construction.In order to efficiently assess the low-carbon economy of the wind-solar-storage power,a large-scale model is constructed.Firstly the capacity of wind-solar-power storage is determined based on the minimum annual operating cost and power shortage rate of the energy storage equipment,and then a carbon emission assessment model is set up according to this model.Secondly,a wind-solar-storage cost assessment model is built based on the life cycle cost theory and a carbon economic performance assessment model is constructed combined with dynamic carbon transaction price.And then three schemes of outgoing transmission of solar power storage,thermal power and bundled wind and thermal power are separately constructed to evaluate the low carbon economy of wind-solar energy storage grid connected under the premise of transporting equal amount of electric energy.Finally,an example is analyzed to verify its validity and rationality of the assessment method.
