在双碳战略背景下,综合能源系统成为探索可再生能源低碳高效利用及多能耦合的主要途径.为兼顾综合能源系统在低碳优化时的稳定性和经济效益,提出了一种含碳捕集、利用与封存-电转气协同运行的综合能源系统分布式鲁棒低碳优化策略.首先,对电转气过程精细化建模,研究氢能的多方面效益,建立 CHP-CCUS-P2G耦合模型,并引入阶梯式碳交易机制,提出一种基于阶梯式碳交易机制的CHP-CCUS-P2G低碳经济调度方法;其次,考虑风光出力的不确定性,以调度系统中可用的历史数据为基础,构建数据驱动下min-max-min的两阶段鲁棒调度模型,采用1-范数和∞-范数约束场景概率分布模糊集;最后,基于列约束生成算法对模型反复迭代求解.算例仿真结果表明,上述模型提高了IES的风光消纳率和经济性,并降低了系统碳排放量.
Distributed Robust Optimal Scheduling of Integrated Energy System with CCUS and P2G
In the context of the dual-carbon strategy,the integrated energy system has become the main way to explore the low-carbon and efficient utilization of renewable energy and multi-energy coupling.In order to take into account the sta-bility and economic benefits of the integrated energy system in low-carbon optimization,this paper proposes a distributed robust low-carbon optimization strategy for integrated energy system with carbon capture,utilization,and stor-age-electricity-to-gas coordinated operation.Firstly,the detailed modeling of the power-to-gas process is carried out to study the various benefits of hydrogen energy.A CHP-CCUS-P2G coupling model is established,and the stepped carbon trading mechanism is introduced.A CHP-CCUS-P2G low-carbon economic dispatch method based on stepped carbon trading mechanism is proposed.Secondly,the uncertainty of wind and solar power output is taken into account,a da-ta-driven min-max-min two-stage robust scheduling model is constructed on the basis of the historical data available in the scheduling system,and the 1-norm and ∞-norm are used to constrain the scene probability distribution fuzzy set.Finally,the model is iteratively solved based on the column constraint generation algorithm.The simulation results show that the above model improves the wind and light consumption rate and economy of IES,and reduces the system emissions.
