摘　　要：虚拟电厂由于集聚分布式能源,能够作为主体参与各类型电力市场的竞争。为了实现虚拟电厂收益最大化,考虑非合作博弈与多类型市场设计虚拟电厂的两级竞价机制,促进虚拟电厂“对内协调、对外统一”的内外部同时优化。基于此,首先从基于边际成本法设计虚拟电厂内部竞价机制;其次,基于多类型电力市场设计虚拟电厂的外部竞价机制;并利用KKT对构建的两阶段模型进行优化求解;最后以某一虚拟电厂进行算例分析,算例结果表明设计的虚拟电厂两级竞价机制能够降低虚拟电厂的运行成本与偏差惩罚成本。Virtual power plants are able to participate in the competition of various types of power markets as the main body due to the gathering of distributed energy.In order to maximize the benefits of virtual power plants,it is considered that non-cooperative game and multi-type market design virtual power plant's twolevel bidding mechanism,and promotes the simultaneous optimization of the virtual power plant's“internal coordination and external unification”.Based on this,firstly,the internal bidding mechanism of the virtual power plant based on the marginal cost method is designed.Secondly,an external bidding mechanism for virtual power plants based on multiple types of power markets is designed,KKT is used to optimize the two-stage model constructed.Finally,an example is analyzed with a virtual power plant.The results of the calculation example show that the two-level bidding mechanism of the virtual power plant can reduce the operating cost and deviation penalty cost of the virtual power plant.
