摘　　要：现有电转气(power-to-gas,P2G)模型忽略了系统内电解制氢与氢气甲烷化2个环节的实际运行状态,导致调度结果与实际情况偏差较大,区域综合能源系统(regional integrated energy system,RIES)多能耦合利用效率较低。为此提出了考虑P2G环节氢能精细化利用的RIES日前调度方法。以系统运行成本和环境成本之和最小为优化目标,建立考虑电转气环节氢能精细化利用的RIES日前优化调度模型。通过算例仿真,验证了所提方法的有效性,相比传统RIES,所提调度模型在有效反应P2G系统实际运行情况的基础上,充分挖掘了其可利用价值,改善了RIES热电耦合性能,提高了系统综合能源利用率与运行经济性。The existing power-to-gas(P2G)models ignore the actual operation state of the water electrolysis and methanation units,which leads to the large deviation between the dispatching results and actual situation,and the utilization efficiency of multi-energy coupling in regional integrated energy system(RIES)is relatively low.In order to solve the problem,a day-ahead RIES dispatching method considering refined utilization of hydrogen in P2G is proposed.Anoptimal dispatching model of RIES considering refined utilization of hydrogen in P2G is established,targeting the minimal sum of operation cost and environment cost.The simulation result shows that compared with the traditional RIES,the proposed model can effectively reflect the actual operation state of P2G system to explore the its available value,and improve thermoelectric coupling performance,enhance the integrated energy utilization efficiency and operational economy of RIES.
