摘要
金融输电权(FTR)的引入可以规避发电商竞争导致的区域电价波动风险,但同时也会对垄断发电商的原有市场力产生影响。应用博弈论通过求解引入FTR前后市场纳什均衡解,比较FTR对典型的3种寡头竞争市场结构模型(Cournot模型、Stackelberg模型和Forchhei mer模型)中发电商原有市场力的影响,并分析了其与市场需求函数及发电成本函数系数的关系。研究结果表明,FTR对市场力影响有递进增长现象:FTR对Cournot模型中的市场力影响最大,对Stackelberg模型次之,对Forchhei mer模型中的市场力影响最小,这与3种模型原有市场力大小排序相同。
Financial transmission right（FTR） provides a financial tool for market participants to hedge against price risks due to transmission congestions.However,at the same time it may also introduce vertical market power.Firstly,the concept of FTR is introduced.Then,based on game theory,the impact of FTR on intrinsic market power is evaluated analytically with Cournot,Stackelberg and Forchheimer models.Finally,the relationship between the influences and the elasticity of demand,cost function coefficients are discussed.The results show that FTR will increase the market power of generators in all three models.Specifically,FTR has the greatest market power in the Cournot model and the least in the Forchheimer model.
