摘要(Abstract)：

在核电机组占比较高的省级电网,为了提高其运行的安全性和灵活性,将发电侧与需求侧调峰资源相结合,建立了核-火-虚拟电厂三阶段联合调峰模型。该模型采用等效负荷的方法处理风电机组出力,并引入碳交易机制,从经济性与低碳性两方面分析运行成本,以系统联合调峰成本最低为优化目标。采用三阶段调度方法,根据系统需求确定核电机组的最优调峰模式与调峰深度,并有效平抑等效负荷的预测误差。利用CPLEX求解器对该混合整数规划问题进行求解,算例仿真验证了所建立模型的合理性与有效性,结果表明所提模型保证了核电机组的安全灵活运行,能够缓解系统的调峰压力,减少火电机组的启停调峰,并有效避免发电机组因负荷预测误差而频繁改变出力,降低了系统的运行成本与碳排放,使经济效益与环境效益得到均衡。
