计及垃圾焚烧电厂-电转气联合运行的低碳协整优化模型

Co-integration Optimization Model for Combined Operation of Waste Incineration Power Plant and Power to Gas with Carbon Trading Mechanism

  • 摘要: 为了促进多能源互补,降低系统运行总成本,建立垃圾焚烧电厂和电转气(Power to gas,P2G)联合运行的低碳协整优化调度模型。将垃圾焚烧电厂、氢燃料电池和新能源发电计入柔性总电源,P2G和烟气处理能耗计入柔性总负荷,建立二者的源-荷协整关系。针对垃圾焚烧电厂燃烧过程中所产生的大量CO2,可结合P2G技术将回收的CO2合成CH4供给天然气系统,通过联合调度将P2G和烟气处理能耗进行负荷转移以平抑新能源波动。考虑碳交易机制,构建以购能成本、碳交易成本、弃风成本和机组运行成本最小为目标的源-荷协整优化调度模型,最后使用仿真来验证所提方法的正确性及有效性。

     

    Abstract: In order to promote the complementarity of multiple energy sources and reduce the total operating cost of the system, a low-carbon co-integration optimization scheduling model for the joint operation of waste incineration power plants and power to gas(P2G) is established. Waste incineration power plants, hydrogen fuel cells, and new energy generation are incorporated into the flexible total power supply, while P2G and flue gas treatment energy consumption into the flexible total load, and a source load cointegration relationship is established between the two. In response to the large amount of CO2 generated during the combustion process of waste incineration power plants, P2G technology is combined to synthesize recovered CO2 into CH4and supply it to the natural gas system. Through joint scheduling, P2G and flue gas treatment energy consumption can be transferred to suppress fluctuations in new energy sources. The carbon trading mechanism is considered and a source load co-integration optimization scheduling model with the goal of minimizing energy purchase cost, carbon trading cost, wind abandonment cost, and unit operating cost is constructed. Finally, simulation is conducted to verify the correctness and effectiveness of the proposed method.
