分析了电力市场环境下发电商串通报价现象,提出结合同步价格行为分析、报价合理性分析、控制力分析等因素,根据价格卡特尔判定原则,应用灰色关联分析和模糊判定理论进行发电商报价的串通竞标判定。分析过程中用隶属度函数衡量各影响因子代表的发电商串通报价可能性的程度,并利用变权法改变权重,突出薄弱环节。通过算例求解证实了该方法的可行性,并且给出了电力市场下有助于防止发电商串通报价的几点建议。
Based on the analysis of the price collusion quotation in the electricity market environment, this paper puts forward the combination of synchronous price behavior analysis, quotation rationality analysis, control force analysis and other factors. According to the principle of price cartel, applying gray relational analysis and fuzzy judgment theory to conduct price quotation Collusive bid determination.
