多寡头动态电力市场的分析

The Analysis of Dynamic Multi-Player Oligopoly in Electricity Market

针对目前我国对电力市场多寡头竞争的研究还不是很深入的情况,在完全信息下,首先建立了多寡头静态模型,找出其纳什均衡解,并进行了稳定性判断;然后建立多寡头动态模型,利用雅可比矩阵的性质判断出系统的稳定性。分析得出:电力市场中发电企业寡头们之间的决策是相互影响并相互关联的,每个企业的发电量可由其他所有企业的发电量之和线性表示。

Based on the fact that the competition in Chinese electric market is oligopolistic, in this paper, we first established a static multi-player oligopoly model and then analyzed the Nash equilibrium and its stability. After that, we established a dynamic multi-player oligopoly model and analyzed its stability. The effects and the relationship of decision-making of these oligopolies are also discussed in this paper, the output of every firm can be expressed in a linear equation of the sum of all other firms＇ outputs.
