摘要 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。 In the provincial power grid with high proportion of nuclear power plant (NPP), in order to improve safety and flexibility of NPP, a three-stage combined peak regulation model of nuclear-thermal-virtual power plant (VPP) is established by combining generation side with demand side peak regulation resources. The model adopts the method of equivalent load to deal with wind power, and introduces carbon trading mechanism to analyze operation cost from two aspects: economy and low carbon. The optimal objective is to minimize the cost of combined peak regulation. Three-stage dispatching method is adopted to determine optimal peak regulation mode and depth of NPP according to system requirements and depress the prediction error of equivalent load. CPLEX solver is used to solve the mixed integer programming problem. Simulation results verify rationality and validity of the model. The results indicate that the proposed model can ensure safe and flexible operation of NPP, release peak regulation pressure of system, reduce start-up and stop-down peak regulation of thermal power units, and effectively avoid frequent changes of the generating units due to load forecasting errors. And it can also reduce operating cost and carbon emission of system and balance the economic and environmental benefits.
