In order to achieve the goal of carbon neutral and carbon peak,a cross-region low-carbon optimal dispatch model is proposed for new multi-region interconnected by DC tie-lines.By introducing the carbon emission cost price and carbon emission right constraints into the cross-region optimal dispatch model,the impact of cross-region optimal dispatch model considering carbon constraints on the output of each type of unit,total system cost and carbon emission is investigated.Through the simulation on three 10-unit 39-node system,solved by analytical target cascading,it is verified that the cross-region low-carbon optimal scheduling model can reduce the total system carbon emissions by increasing the output of low-carbon emitting units and decreasing the output of high-carbon emitting units.The impact of increasing emission reduction under the low-carbon optimal dispatch model on the unit cost and the willingness of the retrofitted unit is investigated.The results show that unit retrofits can effectively reduce system carbon emissions and total costs.
