Novel power system scheduling method and system considering carbon cost conduction

The invention discloses a novel power system scheduling method and system considering carbon cost conduction. The method comprises the following steps: acquiring predicted output, actual generating capacity and unit operation parameters of renewable energy sources; determining wind curtailment and light curtailment penalty cost according to the predicted output, the actual generating capacity, the carbon cost conductivity and the penalty cost model of the renewable energy sources; according to the wind curtailment cost, the light curtailment penalty cost, the unit operation parameters and the electric power system dispatching model, an electric power system dispatching scheme is obtained, and the electric power system dispatching model takes the minimum system operation cost as the target. Electric quantity balance constraint, reserve capacity constraint, unit output upper and lower limit constraint, reserve demand constraint and minimum renewable energy consumption constraint are taken as constraint conditio
