Day-ahead optimal operation of multi-station fusion system considering carbon emission

A day-ahead optimal operation model of multi-station fusion system is proposed to improve the operation economy of the fusion station while reducing carbon dioxide emission and ensuring the reliability of power supply. Firstly, the mathematical model of each substation is established. Then, the objective function of optimal operation of the fusion station is established, which mainly includes the minimum daily operation cost and the minimum carbon trading cost of the fusion station. Then, the constraint conditions for the operation of the fusion station are established. Finally, CPLEX is used to solve the model in order to obtain the practical operation strategy quickly. The validity and rationality of the model are verified through the simulation solution. Furthermore, the payback period of the fusion new energy station and the energy storage station is analyzed, which provides a certain theoretical research basis for the subsequent fusion of other substations and the expansion and development of multiple stations.
