提出考虑气热动态特性的电转气-碳捕集(P2G-CCS)综合能源调度策略。首先,将气热能流特性方程转化至s域,得到二端口传递函数模型,利用卷积定理对其进行Laplace逆变换,从而得到任意时间断面的时域动态模型。其次,在动态模型基础上建立包含P2G-CCS的IES园区,结合碳交易机制减少碳排放。最后以IEEE-39-20-6为例,建立电-气-热能源系统,通过设置不同调度场景进行对比分析。结果表明,所建动态模型和策略有效提高气热网潮流计算效率的同时,降低碳排放,提高系统调度经济性。
Abstract
This article proposes a integrated energy scheduling strategy for power-to-gas and carbon capture systems (P2G-CCS) that considers the dynamic characteristics of gas-thermal. Firstly, the characteristic equation of the gas-thermal energy flow is transformed into the s-domain to obtain a two-port transfer function model. The inverse Laplace inverse transform is carried out on it using the convolution theorem, thereby obtaining the time-domain dynamic model at any time sectioninstant. Then, based on the dynamic model, establish an IES park that includes P2G-CCS is established and combined it with a carbon trading mechanism to reduce carbon emissions. Finally, taking IEEE-39-20-6 as an example, the electric-gas-thermal energy system is established and compared by setting different scheduling scenarios. The results indicate that the established dynamic model and strategy effectively improve the efficiency of flow calculation in gas- thermal networks while reducing carbon emissions and enhancing the economic efficiency of system scheduling.
