寡头垄断电力市场重复博弈模型及其内在复杂性

在双寡头垄断电力市场中建立了一个动态的古诺重复博弈模型。该模型在需求函数及成本函数均为非线性的前提下,考虑电力公司收取过网费,并将初始产量区分为确定性和随机性两种情况,研究了电力生产者通过适应性地调整产量,获得最大化收益的重复博弈过程,分析了不同参数组合条件下系统表现出来的分岔、混沌、密度周期性等复杂性态,这种将确定性与随机性相结合的新的分析方法对于电力生产者在实际生产中确定最佳产量具指导意义。

Inherent Complexity of Repeated Game Model in Electric Power Duopoly

One dynamic repeated Cournot model has been established in electric power duopoly market.Considering the wheeling cost,two circumstances,i.e.definiteness and randomness of initial power output,are analyzed under the conditions that demand function and the cost function are all nonlinear.In these circumstances,the electric power producers modulate output compatibly and obtain the maximium profit,respectively.The complex character displaying by this model,such as fractal,chaos and density cycling are concluded by using the chaotic dynamics theory.This method of combining the definiteness and randomness has important value for electric power producer.
