基于均衡模型的寡头电力市场容量机制研究

为研究容量机制对我国电力市场可能产生的影响,分别针对可靠性期权和战略备用两种容量机制下寡头企业的策略性行为,建立了基于古诺均衡理论的电力市场三重均衡模型。该模型重点考虑了不同容量机制下寡头发电企业的策略性行为对电力交易和用户成本的影响。通过采用伊比利亚半岛电力市场运营商OMIE公开数据,仿真验证了容量机制对市场供需关系的缓解作用。结果同时表明容量机制的引入仅改变了寡头企业行使市场力的方式,寡头企业影响交易价格的能力仍然存在,两种容量机制在不同方面均存在一定的局限性。

Capacity mechanisms of the oligopoly electricity market based on an equilibrium model

To study the possible impact of capacity mechanisms on China''s electricity market, a triple equilibrium model based on Cournot equilibrium theory is established for the strategic behavior of oligarchs under the two capacity mechanisms of reliability option and strategic reserve. The model focuses on the impact of strategic behavior of power generation enterprises on power transaction and user cost under different capacity mechanisms. By using OMIE open data of the Iberian power market operator, the simulation verifies the mitigation effect of the capacity mechanism on market supply-demand relationship. The results also show that the introduction of a capacity mechanism only changes the way oligopoly enterprises exercise market power, and the ability of oligopoly enterprises to influence transaction price still exists. The two capacity mechanisms have certain limitations in different ways.This work is supported by the Science and Technology Project of State Grid Corporation of China "Research on Technical and Economic Characteristics and Operation Mechanism of Energy Internet" (No.1400-202057430A-0-0-00).
