考虑碳排放权价格敏感区间的碳捕集水平优化建模

Carbon Capture Level Optimization Modeling Considering Sensitive Internals of Carbon Emission Allowance

在总量控制与排放贸易的碳排放权交易市场机制下,以发电成本模型为基础,考虑碳排放权购买成本,建立了碳排放权交易模型。由于碳捕集系统消耗捕集能耗,造成电厂利润损失,因此定义了售电损失成本,进而建立了考虑售电损失成本的碳捕集水平优化模型。以具有碳捕集系统的不同费用特性的机组为参照,分别计算不同碳排放权价格和净输出功率下的碳捕集水平,得出碳排放权交易模型和碳捕集水平优化模型下能有效刺激发电商参与碳捕集的碳排放权价格敏感区间,对照分析欧盟碳排放交易体系下碳排放权期货价格和现货价格变化特点,反映了碳捕集水平优化模型的合理、可行和有效。

Considering carbon emission allowance investment cost under the cap-and-trade carbon emission trading scheme,a carbon emission allowance trading model is established based on generation cost model.According to profitability loss result from energy consumption of carbon capture system,the power selling loss is defined and the carbon capture level optimization model is further proposed.The different resources installed with carbon capture system are used as reference to calculate the changes in carbon capture level with net power under different carbon emission allowance prices.The sensitive internals of carbon emission allowance that boost GenCos anticipating in carbon capturing under both carbon trading model and carbon capture level optimization model are acquired.Comparison analysis on spot and future price of carbon emission allowance under European Union Emissions Trading System shows the proposed carbon capture level optimization model is reasonable,feasible and effective.
