机组报价曲线的调整策略分析

在电力市场环境下，发电公司可以通过策略性的投标来获得取最大利润。文章以电力联营体（pool market)的市场模式，根据pool market中发电厂商之间供需的互补关系，研究了机组的报价曲线，分析了机组利润最大化的报价策略，得到了机组最优报价曲线的调整方法，同时讨论了在考虑电力需求弹性影响时此策略的均衡解。最后，通过算例说明了厂商在不同条件（如市场势力、协作与非协作报价、考虑电力需求弹性等）下的报价策略。文中所提的最优策略也可推广到发电公司之间的竞争。

ANALYSIS OF ADJUSTMENT STRATEGIES OF BIDDING CURVE

In electricity market the power generationcompanies can gain maximum profits with tactical bidding. Based on the pool market mode, according to thecomplementation of supply and demand among the powergeneration companies in pool market, the bidding strategy and research of the bidding curves of generating sets, the bidding strategy for maximizing the profit of generating sets isanalyzed and the adjustment method of optimal bidding curve for generating set is obtained. At the same time, the balance solution of this strategy is discussed while the elasticity ofelectricity demand is considered. Finally, the bidding strategy for power generation companies under different conditions, e.g., existing market power, collaboration and non-collaboration bidding, considering the elasticity of power demand, etc., isdescribed.
