基于低碳发展的电能结构调整与优化——以四川省为例

Paths and Countermeasures for Adjusting and Optimizing Electrical Energy Structure Based on Low-carbon Development——A case study of Sichuan Province

四川是全国重要的水电能源基地,但煤电在全省的发电结构中仍占相当比重,电能结构亟须优化。从水-火电结构、火电能源消耗以及SO2、CO2排放情况、消费结构、补偿问题、脱硫、脱硝电价等方面分析了四川电能结构的现状与存在的问题。基于低碳发展的视角,从大力拓展水力发电、适度发展天然气发电、积极开发可再生能源发电和稳步缩减煤电发电等方面探讨电能结构调整与优化的路径,提出了针对政府、电力行业和电力企业调整与优化电能结构的对策和建议。

Sichuan is an important hydroelectric energy base of China,but the coal-based electricity still accounts for a considerable proportion of the power generation structure,which needs to be optimized urgently.The status quo and the existing problems of electrical energy structure of Sichuan province are analyzed from the aspect of hydro-thermal power generation structure,thermal power consumption,emissions of SO2 and CO2,consumption structure,compensation issues,electricity price of desulfurization and denitration.In the view of low carbon development,the path of adjusting and optimizing the electrical energy structure is discussed from four aspects,i.e.vigorously expanding hydropower generation,appropriately developing natural gas-fired generation,actively accelerating renewable energy generation,and steadily reducing coal-based electricity.Finally,some countermeasures and suggestions for government,electrical industry,and power generation enterprises are proposed to adjust and optimize the electrical energy structure of Sichuan province.
