【摘要】：2002 年底,国家电力公司正式“厂网分开”,新成立了五大发电集团和两家电网公司,为实行发电商竞价上网奠定了坚实的基础,标志着中国电力市场化改革已迈出了关键的一步。在竞价上网的过程中,所有的发电公司都想使自身的收益最大化,而电网公司却想使购电费用最小化。在建立电力市场过程中,找到一种有效合理的竞价模式就显得很重要,既激励发电企业强化管理、提高效率, 从而降低了上网电价,又要考虑到电力改革的市场风险与平稳过渡。本文对国内试点的两种竞价模式(差价合约模式与有限竞价模式)进行了深入研究与分析,揭示了两种竞价模式的本质区别在于发电商的上网电量小于合约电量时收益的结算差别;运用博弈论、微观经济学、电力市场理论的相关部分分析了在发电侧电力市场中,各发电公司和电网公司面对两种竞价模式的博弈行为,基于发电商竞价是完全信息博弈模型,相继分析了一次性博弈和重复博弈的均衡;在分析重复博弈时,研究了发电商合作的必要条件,为竞价规则的设计提供了防止发电商合谋的思路;在完全信息静态博弈的基础上,建立了在两种竞价模式下,由多个发电商参加的产量博弈模型,并给出了数学解;最后在综合比较两种竞价模式的基础上,本文提出了某个区域电网的电源结构对选择竞价模式的影响。本文主要是为当前的中国电力市场改革的实施提供一些理论支持,希望通过对竞价模式的理论研究,深化对中国电力工业市场化改革的认识。
[Abstract]:In end of 2002, the State Power Company officially "separated the power plant and network", and set up five major power generation groups and two new power generation groups. The home appliance network company has laid a solid foundation for the implementation of power generation companies bidding for the Internet, marking the marketization of electricity in China. The reform has taken a crucial step. In the bidding process, all the power generation companies want to make their own While grid companies want to minimize the cost of buying electricity, they want to maximize revenue. In the process of building a power market, find An effective and reasonable bidding model is very important, which not only motivates power generation enterprises to strengthen management, but also improves efficiency. Therefore, the electricity price is reduced, and the market risk and smooth transition of electric power reform should be taken into account. In this paper, two bidding modes (contract for difference model and limited bidding model) are discussed in detail. Through research and analysis, it is revealed that the essential difference between the two bidding modes lies in the fact that the power on the net of the generator is less than the contract. The difference of income between electricity and electricity; applying Game Theory, Microeconomics, and relevant parts of electricity Market Theory In the generation side electricity market, each generation company and the power grid company face the game of two bidding modes. Based on the complete information game model, the one-off game and the repeated game are analyzed one after another. In the analysis of repeated game, the necessary condition of power generation cooperation is studied, which is proposed for the design of bidding rules. On the basis of static game of complete information, two kinds of bidding are established. In this paper, the output game model with the participation of multiple generators is given, and the mathematical solution is given. Finally, a comprehensive comparison is made On the basis of two bidding modes, this paper proposes a new method for selecting bidding modes in a regional power grid. Influence This paper is mainly to provide some theoretical support for the implementation of the current reform of China's electricity market. The theoretical research on the bidding mode, deepening the understanding of the market-oriented reform of China's electric power industry.
