A Multi-source Coordinated Model Considering Nuclear Power Participation in Peak Load Regulation

Abstract

A multi-source coordinated model considering nuclear power participation in peak load regulation is proposed. On the premise of meeting the safety constrains of nuclear power plant when participating in optimal operation, It's capability of peak load regulation is effectively improved. The multi-source coordinated model realizes the maximum absorption of wind power output and the improvement of system economy. The model taking the minimum total cost of power system as the objective function, using two-stage scheduling to determine whether nuclear power units participate in peak load regulation, and taking account of the deep peak load regulation of the thermal power units at the same time. Simulation results verify the validity of the model. With multi-source coordinated model, nuclear power units can choose the most economical load following scheme according to the actual situation on the premise of meeting safety constraints. The total cost of power system after optimization is less than the model when nuclear power plants running with basic load. And more wind power output can be absorbed at the same time.
