考虑电转气和气网注氢技术的综合能源系统优化调度
Optimal Dispatch of Integrated Energy System Considering Power-to-gas Coupled Gas Grid Hydrogen Injection Technology
摘要
Abstract
The flexible application of hydrogen and methane,generated through the two stages of electrolytic water and methanation in the power to gas(P2G)system,can promote the capability of the integrated energy system(IES)in absorbing surplus renewable energy.The traditional P2G system only considers methane as the fuel for the gas units,neglecting to fully exploit the high electrolysis rate of hydrogen.Con-sequently,this leads to an increase in the number of energy cas-cade conversions and a subsequent rise in energy loss.In this paper,we apply the hydrogen and methane coupled hydrogen injection into gas grid(HIGG)technology,produced in two stages of the P2G system,to promote the absorption of renew-able energy in IES.Based on the concept of energy hub,the economic optimal scheduling of IES system is transformed in-to a mixed integer programming problem.The simulation ana-lysis of two scenarios demonstrate that compared with the tradi-tional P2G system which only employs methane,the applica-tion of P2G coupled with HIGG technology in the IES system can reduce the number of energy cascade conversions and cost input,significantly improving the economic viability and envir-onmental sustainability.关键词
