含耦合P2G和CCS的园区级综合能源系统优化调度

Optimal Scheduling of Park-level Integrated Energy System with Coupling of P2G and CCS

为提升园区级综合能源系统PLIES(park-level integrated energy system)的可再生能源消纳能力以及碳排放效益,提出含耦合电转气P2G(power-to-gas)和碳捕获系统CCS(carbon capture system)的优化调度模型。首先,建立了一个P2G与CCS耦合的模型,将该耦合模型引入到以燃气热电联产为主要机组的PLIES。其次,以经济运行成本最低为目标函数,构建了含耦合P2G和CCS的PLIES低碳经济调度模型。最终,本文以北方某工业园区为例,设置4种不同场景进行算例分析,仿真结果表明所提出模型可以有效减少CO_(2)排放并且实现可再生能源的高效利用。

To improve the renewable energy accommodation capacity and carbon emission benefits of a park-level inte⁃grated energy system(PLIES),an optimal scheduling model with coupling of power-to-gas(P2G)and carbon capture system(CCS)is proposed.First,a coupling model of P2G and CCS is established,which is further introduced into PLIES with gas-fired combined heat and power as the main unit.Second,the lowest economic operation cost is taken as the objective function,and a low-carbon economic scheduling model of PLIES with coupling of P2G and CCS is con⁃structed.Finally,an industrial park in North China is taken as an example,and four different scenarios are configured for example analysis.Simulation results show that the proposed model can effectively reduce CO_(2)emissions and achieve an efficient utilization of renewable energy.
