摘要
考虑电力市场的动态性、系统性和长期性等因素,市场中会有很多"反直觉"的问题,即正确推论与人们的直觉相反.为此,以分区定价机制为例,对电价机制中的反直觉问题进行探讨.首先,以机制设计理论为基础,分析机制设计中的激励相容问题及与反直觉现象的关系;然后,针对市场主体的动态特征,对反直觉问题提出静态分析与动态分析相结合的分析方法;最后,以发电侧节点加权平均价格作为结算价格为例,从上述2个层面对该机制下可能产生的反直觉问题进行仿真分析.结果表明:该机制下由于部分市场主体申报考虑个体理性的价格,反而不会降低购电成本.需要对该类机组设计相应的成本补偿和分摊机制以满足市场的激励相容约束.
Abstract
Considering factors such as the dynamic,systematic,and long-term nature of the electricity market,there are often many counter-intuitive issues,the correct inferences contradict people's intuitions.In this regard,taking the zonal pricing mechanism as an example,counterintuitive issues within the electricity pricing mechanism are explored.Firstly,based on mechanism design theory,Firstly,based on mechanism design theory,the incentive compatibility issues in mechanism design and their relationship with counter-intuitive phenomena are analyzed.In response to the dynamic characteristics of market participants,an analytical approach that combines static and dynamic analyses is presented for addressing counterintuitive issues.Finally,using the generation-side nodal weighted average price as the settlement price as the example,a simulation analysis on potential counter-intuitive issues arising from the mentioned mechanism is carried out from both the static and dynamic perspectives.The results indicate that under this mechanism,due to some market participants declaring prices based on individual rationality,it does not necessarily lead to a reduction in electricity procurement costs.To address this,there is a need to design corresponding cost compensation and sharing mechanisms for such units,ensuring compliance with incentive compatibility constraints in the market.
