Abstract：With the rapid development of nuclear power technology, it is an inevitable trend for large capacity nuclear power units to be connected to the power grid to achieve low carbon and environmental protection. However, with the increase of load peak-valley difference and the increase of intermittent power supply permeability, it is urgent for nuclear power units to share the peak pressure of the power grid in a flexible operation mode. Based on the actual operation characteristics of nuclear power units, the peak regulation depth of nuclear power units was linearized. The characteristics of peak shaving and valley filling of carbon capture power plants with integrated flexible operation mode were analyzed to realize binding peak regulation of nuclear-carbon capture units. Then, fuzzy parameters were introduced to characterize the uncertainty of wind power and load. On the premise of considering the safety and economy of nuclear power peak regulation, a multi-source coordinated fuzzy optimal scheduling model considering the benefit of wind power consumption was established by minimizing the total cost of joint operation as the objective function. The simulation example verifies the validity of the proposed model and method. The results show that the optimal dispatching model can improve the flexibility of power network dispatching and realize the economic and low-carbon operation on the basis of ensuring the safe operation of nuclear power.
