| Summary: | Faced with a high proportion of new energy power systems in the future, thermal power units will become the main peaking power source, and the reasonable recovery of their capacity value will become a focus of attention. To plan the power supply structure while considering the capacity tariff of thermal units and support the development of low-carbon energy, this paper proposes a two-tier power supply planning model that coordinates the scenery-to-fire ratio with the capacity tariff and proposes a capacity compensation mechanism for thermal units based on the effective capacity. With the gradually increasing ratio of scenery to fire, the capacity tariff compensation for thermal power units will be on the rise, providing a reference for the coordinated development of power supply planning and power market under the high proportion of new energy.
