摘　　要：为提升高比例可再生能源的消纳水平和推进区域低碳化,建立电制氢合成甲醇的广义储能模型参与虚拟电厂(VPP)调度,提出考虑多元柔性负荷的VPP分层优化策略。其中上层模型通过广义储能跟踪风光发电并消纳部分出力,中层模型通过分时电价和激励进行负荷灵活调节,下层模型通过火电机组、广义储能以及对外界电能交易保证VPP电能供需平衡。使用CPLEX商业求解器对所建模型进行求解分析,并与多个VPP方案进行对比。结果表明,所提策略能够有效促进可再生能源消纳,提高VPP的低碳效益,对于工程实践具有重要理论指导价值。To enhance the consumption of high-penetration renewable energy and promote regional decarbonization,a generalized energy storage model for the synthesis of methanol via electrolysis of hydrogen is established to participate in the dispatch of a virtual power plant(VPP).A hierarchical optimization strategy for VPP considering multiple flexible loads is proposed.In the upper-level model,the generalized energy storage tracks the wind and solar power generation and absorbs part of the output.The mid-level model flexibly adjusts the load through time-of-use pricing and incentives.The lower-level model ensures the balance of power supply and demand in VPP through the thermal power units,the generalized energy storage,and the external electricity transactions.The CPLEX commercial solver is used to analyze and solve the proposed model.By comparing multiple VPP schemes,it is demonstrated that the proposed strategy effectively promotes the consumption of renewable energy,enhances the low-carbon benefits of VPP,and provides the important theoretical guidance for engineering practice.
