在电力市场环境下,发电公司可以通过策略性的投标来获取最大利润。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。
In the electricity market environment, power generation companies can obtain the maximum profit through strategic bidding. Based on the market model of pool market and the complementary relationship between supply and demand of generators in the pool market, this paper studies the quotation curve of the unit, analyzes the quotation strategy of unit profit maximization and obtains the optimal bidding curve , And discussed the equilibrium solution of this strategy when considering the effect of the elasticity of electricity demand. Finally, an example is given to illustrate the firm’s bidding strategy under different conditions (such as market forces, cooperative and non-cooperative bidding, considering the elasticity of demand for electricity). The optimal strategy mentioned in the article can also be extended to the competition among power generation companies.
