项目摘要

The deregulation trend in the electric power market since 1980's is partly due to the anticipation that introducing a pool market boosts the power companies' competitiveness and also lowers the electricity prices. Through California Electricity Crisis, however, it has been well understood that a pool market principle sometimes leads to the investment circumspection and the resultant price fluctuation. In general, power companies in the locally-monopolized market can easily invest in power-generation plants so as to meet the power demand, and the deregulation of the power industry inevitably makes the investment more risky. Furthermore, there have been invented no rules for making sufficient incentives in strategic investment. Stabilization of the power supply under the deregulated power market is an important requirement for the deregulated framework of the power marketThis study aims to develop a simulation model of the deregulated power market and to design the appropriate market rul … More es that can stabilize the power prices. The investment behavior of power companies and the rules for the pool market deals are modeled to analyze the necessary conditions for stabilizing the power supply. The simulation results indicate that the large power company can make investment in the power plants with high power price. On the contrary, the small power company tends to invest for the power plant with low power price. It can be also implied that the pool market with the small-scaled power companies is more competitive than the market with the large-scaled power companies. In addition, it is shown that a pool market with small-scaled power companies is not accompanied by the stable capital investment and more rapidly face with the adverse situations from overinvestment or underinvestment than a power market composed by large-scaled companies. In conclusion, the competitive pool market can be realized under the deregulated framework, but some rules that control the companies' investment so as to stabilize the market behavior are unavoidably required Less

20世纪80年代以来电力市场的放松管制趋势部分是由于预期引入联营市场可以提高电力公司的竞争力并降低电价。然而，通过加州电力危机，人们已经充分认识到，联营市场原则有时会导致投资谨慎和由此产生的价格波动。一般来说，在本地垄断市场下，电力公司很容易投资兴建发电厂，以应付电力需求，而电力行业的撤销规管，无可避免地令投资的风险增加。此外，还没有发明任何规则来对战略投资进行充分的激励。在电力市场开放条件下，电力供应的稳定性是电力市场开放框架的重要要求。本文旨在建立电力市场开放的仿真模型，并设计合适的市场规则。 ...更多信息这可以稳定电价。通过对电力公司投资行为和联营市场交易规则的建模，分析了稳定电力供应的必要条件。仿真结果表明，大型电力公司可以在电价较高的电厂进行投资。相反，小电力公司倾向于投资于低电价的发电厂。这也意味着，与小规模的电力公司的联营市场比与大规模的电力公司的市场更具竞争力。此外，研究表明，由小规模电力公司组成的联营市场不伴随着稳定的资本投资，并且比由大规模公司组成的电力市场更快地面临投资过度或投资不足的不利局面。总之，在放松管制的框架下，竞争性联营市场是可以实现的，但必须有一些规则来控制公司的投资，以稳定市场行为。
