摘　　要：现货电能量市场与备用市场在市场组织与出清模型上衔接紧密,为研究不同的衔接机制对总发电成本、能量备用市场价格等市场绩效指标的影响,建立日前电能量备用联合出清模型,并依据出清次序和机组组合阶段目标函数成本项这2个划分标准来建立4种顺次出清模型。基于IEEE 118节点系统开展仿真,研究分析不同衔接机制下的有关电力市场绩效指标及形成差异的原因,并通过改变系统参数与边界条件,研究不同衔接机制下市场出清的可行域。结果表明,联合出清模式的总发电成本、市场电价等绩效指标更优,可以更好地调用系统灵活资源,同时还具有最大的出清可行区间。能量优先出清同时在机组组合综合考虑备用成本的顺次模式,在总发电成本、市场电价等绩效指标以及出清可行域上仅次于联合出清模式。最后基于仿真及理论分析结果给出了在备用市场建设初期,宜采用“先能量后备用,能量出清结果作为备用市场出清边界条件,机组组合考虑备用成本”的顺次出清模式,以及长期转向联合模式的建设方案。The spot electric energy market and reserve market are closely integrated in terms of market organization and clearing model.To study the impact of different integration mechanisms on the overall generation costs,energy-reserve market prices,and other market performance indicators,this paper establishes a joint clearing model for day-ahead electricity-energy and reserve market.Based on the clearing sequence and different objective function cost items at the unit commitment stage,it builds four sequential clearing models.It conducts simulation on the IEEE118 node system to study and analyze the relevant performance indicators of the power market under different integration mechanisms and the reasons for the differences in formation.By changing system parameters and boundary conditions,the paper also studies the feasible clearance domain of the market under different integration mechanisms.The results show that the total generation cost and market electricity price of the joint clearing model are superior,which can better utilize system flexible resources and also have the largest feasible clearance interval.The energy-priority sequential mode,which considers reserve costs comprehensively in unit commitment,ranks second only to the joint clearing model in terms of overall generation costs,market electricity prices,and feasible clearance domains.Finally,according to the simulation and theoretical analysis results,the paper provides construction schemes for short-term sequential mode and long-term joint mode of integrating reserve and spot electricity-energy markets.
