考虑电-气综合需求响应的综合能源系统低碳经济调度

Low-carbon Economic Dispatch of Integrated Energy System Considering Integrated Power Demand Response

随着“碳达峰”和“碳中和”目标的提出,低碳电力更加符合社会发展的需求。氢气具有清洁无污染、能量密度大等特点,合理利用氢能源为综合能源系统的发展提供了新的方向。基于此构建了含制氢-储氢设备的综合能源系统低碳经济调度模型,引入电-气综合需求响应并考虑碳排放惩罚成本,以系统总成本最优为目标函数,利用粒子群算法对实际算例进行分析求解。仿真结果表明通过引入综合需求响应和制氢-储氢设备,可提高可再生能源的消纳水平,降低系统的成本,减少系统的碳排放。

With the‘emission peak’and‘carbon neutrality’goals proposed,low-carbon electricity is more in line with the needs of social development.Hydrogen has the characteristics of clean,pollution-free and high energy density.The rational use of hydrogen energy provides a new direction for the development of integrated energy systems.Based on this,a low-carbon economic dispatch model of an integrated energy system containing hydrogen production and hydrogen storage equipment is constructed.The integrated electricity-gas demand response is introduced and the carbon emission penalty cost is considered.The total system cost is optimal as the objective function,and finally the particle swarm algorithm is used to analyze and solve actual calculation examples.The simulation results show that the introduction of integrated demand response and hydrogen production and storage systems can improve the consumption level of renewable energy,reduce the cost of the system,and reduce the carbon emissions of the system.
