Open Simulation Framework for Deregulated Electric Power Market

20世纪80年代以来，电力市场出现了放松管制的趋势，部分原因是人们预期引入联合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，我们很好地理解了池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，处于局部垄断市场的电力公司可以很容易地投资于发电厂以满足电力需求，而电力行业的放松管制不可避免地增加了投资的风险。此外，在战略投资中没有制定足够激励的规则。电力市场放松管制下的电力供应稳定是电力市场放松管制框架的重要要求，本研究旨在建立放松管制下的电力市场模拟模型，并设计合适的市场规则，以稳定电价。通过对电力公司投资行为和池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，大型电力公司可以投资高电价的电厂。相反，小电力公司倾向于投资于电价较低的电厂。这也意味着小规模电力公司的市场竞争比大型电力公司的市场竞争更激烈。此外，小规模电力公司组成的电力市场没有稳定的资金投入，比大规模电力公司组成的电力市场更容易面临过度投资或投资不足的不利局面。综上所述，在放松管制的框架下，竞争池市场是可以实现的，但不可避免地需要一些控制公司投资以稳定市场行为的规则

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
