中国的碳排放交易市场建设处于试点阶段,碳排放的定价成为理顺能源价格链的重要环节.为充分体现碳排放配额的市场价值,考虑碳排放定价的市场需求、排放上限、发电成本以及减排成本4个因素,以发电商效益最大化为目标构建电力市场下的Nash均衡模型;通过模型的求解测算出市场均衡状态下碳排放的价格水平以及发电商的收益状况;为进一步了解敏感因素对碳排放定价的影响程度,分别就4个重要因素对碳排放定价的影响进行敏感性分析,结果表明,市场需求、减排成本与碳排放价格呈正相关,排放上限、发电成本与碳排放价格呈负相关.
Carbon trading pilots are being established in China,and the pricing of carbon is a key issue in a carbon market.A pricing model based on Nash Equilibrium theory is established in this paper to explore the market value of carbon allowance in the power market.This model considers the influencing factors such as the market requirements,carbon emission cap,generation cost and emission reduction cost and so on,and is established with the objective of maximizing the benefit of power plants.The equilibrium price of carbon allowance and the corresponding benefit of the power plants is calculated by resolving the model.Sensitivity analysis is then made to evaluate the influence of the aforementioned influencing factors on the pricing of carbon,the results indicates that carbon price is positively correlated with carbon emission reduction cost and the market demand,and is negatively correlated with carbon emission cap and the generation cost.
