As the proportion of renewable energy in the power system continues to increase, the problems of abandoning wind and photovoltaics and peaking have become more prominent. Therefore, this paper establishes a day-ahead scheduling model for future power systems. First, this paper establishes a wind-photovoltaic-hydropower-thermal power-energy storage joint optimization model, and the proportion of thermal power installed capacity is less than 40%. Second, this paper converts the power of abandoning wind and photovoltaic and the number of start-stops of thermal power units into costs to make the objective function more streamlined. Third, this paper introduces a carbon treatment fee to make the model more suitable for the future electricity market. Fourth, this paper adopts Pareto optimal frontier for dual-objective optimization, which realizes the combination of subjective and objective. Finally, the model proposed in this paper has achieved the expected purpose through the verification of the example.
