摘要
为提高清洁能源利用率,实现电力系统低碳经济运行,构建聚合风电、光伏、富氧燃烧电厂、燃气轮机、余热回收利用系统和质子交换膜电解槽的虚拟电厂优化调度模型。首先,从余热回收利用的角度,对电解槽、甲烷化和质子交换膜燃料电池进行建模,并考虑电解槽与富氧燃烧电厂的联合运行;其次,从富氧燃烧电厂的角度考虑低碳经济运行的可行性,并以运行成本最小为目标,构建虚拟电厂低碳优化调度模型;最后,为验证所建模型的可行性与有效性,设置5种场景,对虚拟电厂的运行结果对比分析。研究结果表明,该方法既能有效促进清洁能源消纳,又可将余热回收进行利用,还能同时实现虚拟电厂的低碳经济运行。
In order to improve the utilization rate of clean energy and achieve low-carbon and economic operation of the power system,this paper constructs an optimal scheduling model of virtual power plants(VPPs)that aggregate wind power,photovoltaic power,oxygen-enriched combustion,gas turbine,waste heat recovery and utilization system,and proton exchange membrane electrolyzer(PEMEL).Firstly,the electrolyzer,methanation,and proton exchange membrane fuel cell(PEMFC)are modeled from the perspective of waste heat recovery and utilization,considering the joint operation of electrolyzers and oxygen-enriched combustion power plants.Next,from the perspective of oxygen-enriched combustion power plants,the feasibility of achieving low-carbon and economic operation is analyzed.Taking the minimization of operating costs as the objective function,a low-carbon optimal scheduling model for the VPP is constructed.Finally,in order to verify the effectiveness and feasibility of the established model,five scenarios are set up to compare and analyze the running results of the VPP.The results show that the proposed method can effectively promote the consumption of clean energy,utilize recovered waste heat,and achieve low-carbon and economic operation of VPPs.
