Abstract：With the accelerating process of building a new type of power system that adapts to the high proportion of new energy,coal power units are transforming from traditional power generation resources to flexible regulation resources.While the fixed costs of coal power units are high,when their generation space is further suppressed,as China's current power market still fails to fully reflect the peak and regulation value of coal power,it makes it difficult to recover the costs of coal power units,and the incentive for flexibility transformation of coal power units is not high.In order to protect the income of coal power units and promote the transformation of coal power units,this paper constructs a variety of tariff mechanism analysis model to stimulate coal power units to provide flexibility in regulating capacity,starting from a system of peak hour scarcity tariffs,the capacity cost of full compensation for the cost of electricity competition tariffs,the capacity cost of partial compensation for the remaining integration into the cost of electricity competition tariffs,and a system of small coal power units in a strategic standby capacity tariff mechanism of several modes,and designing a system applicable to different power market environments.The power pricing strategies applicable to coal power units in different power market environments are designed,providing a theoretical basis for the formulation of compensation incentive policies for coal power units in different regions.
