摘要
优化电源规划是应对电力系统"碳锁定"效应,促进电力系统减少碳排放的重要举措。考虑到国内以煤炭为主的能源结构,有必要分析碳排放及燃煤约束对电源规划的影响。在分析碳捕集电厂运行特性的基础上,建立了考虑碳排放及燃煤约束的低碳电源规划模型,并在模型中采用典型日的运行校验系统是否具备足够的调峰能力。基于国内典型地区电力系统,对不同碳排放总量约束、不同可再生能源发展场景及不同煤炭资源供应约束下的常规火电及碳捕集电厂的扩展规划进行了优化分析,分析结论表明碳捕集电厂可以充分适应电力系统的碳减排目标,满足新能源大规模发展的调峰需求。
To reduce carbon emissions is a new task of power industry in the new era of low carbon economy. Considering the coal dominated energy structure in China, it is necessary to conduct analysis on the effect of carbon emission and coal supply constraints on generation expansion planning. Based on the analyses of the operational characteristics of carbon capture and storage （CCS） power plant, a low-carbon generation expansion planning model considering carbon emission and coal-supply constraints is formulated. Typical days are adopted in the model to check if the system has sufficient peak load regulation capacity. By taking a regional power system as an example, expansion planning of regular thermal power plant and CCS power plant is conducted in different scenarios of carbon emission constraints, renewable energy development and coal supply constraints. The results show that CCS power plant can adapt to the low-carbon emission target while providing regulation capacity for large-scale renewable energy development.
