摘要
研究了电力期货在水火电发电资源优化配置中的应用。给出了考虑同一或不同区域电力市场时,2发电商之间在不同发电成本和发电收益下进行电力期货交易的实现方式和所得收益的计算模型。理论分析和具体算例都显示,水火电发电商之间进行期货交易,既可以通过置换发电资源来充分发挥丰水期水电的成本和环保优势,促进发电资源的优化配置和社会整体发电成本的降低,还可以在枯水期保障充裕的社会整体电力供给。同时期货交易还会带来额外的价差收益,发电商通过期货价格来分享这一额外收益,也符合其发电效益最大化的原则。因此电力期货是一种非常有效的水火电资源优化配置手段。
The application of electricity features in optimized allocation of thermal and hydroelectric power resources is researched. The implementation of the transaction of electricity features between two gencos in the same electricity market or in different regional electricity markets under different generation costs and benefits as well as corresponding computation model are given. Results of both theoretical analysis and concrete calculation example show that the transaction of electricity features between thermal gencos and hydroelectric gencos not only can fully use the advantages of hydroelectric generation cost and environment protection during wet season can by substituting generation resources and promote optimized allocation of generation resources as well as reduce the global social generation cost, but also ensure abundant global social power supply during dry season. Besides, features transaction can bring additional income from difference in price and gencos can share such an additional income by drafting features price, and features transaction conforms with the genco’s principle of maximizing generation benefit. Thus, electricity features can be regarded as a very efficient manner for the optimized allocation of thermal and hydroelectric power resources.
