PX市场中买电代理商的经济模型及利润分析

全球电力市场化为电力工业提出了一系列新的研究课题。现在各电力公司不仅要处理传统的调度问题，还要考虑新市场机制下的经济问题。基于PX市场中MCP和MCQ的形成机理，探讨了买电代理商的买电经济模型，并进行了利润分析。文中用美国电力市场的数据进行市场仿真，找出了使利润最大的成交电价和成交电量，并给出了相应的竞标策略，结果表明该研究可为买电代理商寻求最优竞标策略和定价策略提供辅助决策作用。

ECONOMIC MODEL AND PROFIT ANALYSIS FOR POWER DEMANDERS IN PX POWER MARKET

The electric power industry worldwide is facing a new spectrum of issues with the introduction of power market.Every power supplier company not only deals with traditional schedule problems. but also auction, bidding and othereconomic problems under the new market structure. By analyzing the market mechanism, an economic model is developed andprofit analyses are performed in the paper for power demanders to select bidding strategies. The numerical simulation resultsbased on the data of a US power market show the market cleaning price (MCP). the market cleaning quantity (MCQ) and thebidding strategy that maximizes the profit. The research presented in this paper can provide decision support for powerdemanders to optimize their demand bidding strategy and to determine the energy price to sell.This project is jointly supported by National Natural Science Foundation of China (No. 59937150). 863 Project of China(No. 863--511--9845-004) and National Outstanding Young investigator (No. 6970025).
