摘要

提出了一种考虑核电参与调峰的多源协调模型。在满足核电站参与优化运行安全约束的前提下,有效提高了调峰能力。多源协调模型实现了风电输出的最大吸收和系统经济性的提高。该模型以电力系统总成本最小为目标函数,采用两阶段调度确定核电机组是否参与调峰,同时考虑火电机组的深度调峰。仿真结果验证了该模型的有效性。采用多源协调模型,核电机组可以在满足安全约束的前提下,根据实际情况选择最经济的负荷跟随方案。优化后的核电系统在基本负荷运行时的总成本低于模型。同时可以吸收更多的风电输出。

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