In order to encourage coal-fired generating units to adopt more environmentally friendly power generation methods and im-prove the stability of power system operation,the low-carbon operation methods for collaborative coal-fired power generation units in new power systems were studied.With the objective function of minimizing the net load fluctuation of the new power system and the con-straints of wind and light abandonment of new energy and charge and discharge of the energy storage system as constraints,the upper level optimization scheduling model of the new power system in collaboration with the coal-fired generating units for low-carbon opera-tion was established to optimize the net load curve of the new power system and improve the stability of its operation.With the objective function of minimizing the total cost of the new power system in collaboration with the coal-fired generating units and minimizing carbon emissions,and the constraint conditions of the coal-fired generating unit output constraint and the power balance constraint of the new power system,the optimization scheduling model of the lower layer was established by introducing the Chinese Certified Emission Re-duction(CCER)and the net load output of the upper model.Encourage coal-fired generating units to adopt more environmentally friendly power generation methods,and realize the low-carbon operation of new power systems in collaboration with coal-fired genera-ting units.The experimental results indicate that the method can effectively optimize the net load of the new power system and reduce the fluctuation amplitude of the net load,and can effectively reduce the total operating cost and carbon emission of the new power system in collaboration with the coal-fired generating unit.
