    摘要:

    考虑到碳排放重灾区居民的环境诉求,提出基于区域碳排放均衡性的综合指标碳排放权分配方案,以基准法分配方案和发电厂所在区域的碳排放量为标准,根据熵值法进行碳配额分配。为了研究碳价对电力系统碳排放量的影响,建立了电力系统三阶段最优阶梯碳价模型,第1阶段为正常情况下的机组组合问题,第2阶段为寻找最差的N-1故障场景,第3阶段为最优阶梯碳价的求解模型,通过C&CG算法和二分法求解。算例分析表明,在减排任务较小时,阶梯碳价能够以较少的碳交易成本控制系统碳排放量;基于综合指标的碳排放权分配方案在平衡区域碳排放差异性方面效果显著。

    Abstract:

    Considering the environmental demands of residents in the hard-hit areas of carbon emissions, an allocation scheme of comprehensive index carbon emission rights based on regional carbon emission balance is proposed. The allocation scheme is obtained by entropy method with indicators of the benchmark scheme and regional carbon emissions of the plant. In order to study the effects of carbon price on emissions in power system, a three-stage optimal tiered emission price model is established, in which the first stage is unit commitment problem in normal conditions. The second stage is to find the worst fault scenarios, and the third stage is the solution of the optimal stepped carbon price. The model is solved by the column and constraint generation(C&CG) algorithm and dichotomy. Case study shows that when the emission task is small, tiered emission price could control carbon emissions with less carbon trading cost. Carbon emission right allocation scheme based on comprehensive indicators has a significant effect on balancing regional carbon emissions differences.
