摘　　要：【目的】随着新能源的大规模发展,新能源出力不确定性和波动性问题展现出来,而为了弥补新能源出力缺点,火电机组承担起了调峰作用。为了提升火电机组的调峰能力,对其调峰特性进行了研究。【方法】首先,以某350 MW供热机组作为分析对象,应用仿真软件搭建热力系统模型,并验证该模型的精确性。其次,以蓄热系统为辅助系统,研究机组在满足供热需求情况下的机组调峰能力,并分析蓄热等储能单元对机组调峰能力的影响。最后,采用启发式粒子群算法对蓄热水罐运行策略进行优化,得到随热负荷变化的储热罐最优运行模式。【结果】通过蓄热水罐与火电机组耦合的方法有效提升了机组的调峰和供热能力,并提出可以根据实际热负荷数据确定最大化收益的运行模式。【结论】该方法对机组的运行策略具有指导意义。[Objectives]With the intervention of new energy,the uncertainty and volatility problems of new energy output have been shown.In order to make up for the shortcomings of new energy output,thermal power units have assumed the role of peak regulation.In order to improve the peak-load capacity of thermal power units,the peak-load characteristics were studied.[Methods]Firstly,a 350 MW heating unit was taken as the analysis object.The simulation software was used to build the thermal system model,and the accuracy of the model was verified.Secondly,with the heat storage system as the auxiliary system,the peak-load capacity of the unit under the condition of meeting the heating demand was studied,and the influence of energy storage units such as heat storage on the peak-load capacity of the unit was analyzed.Finally,the heuristic particle swarm optimization algorithm was used to optimize the operation strategy of the storage tank,and the optimal operation mode of the storage tank changing with the heat load was obtained.[Results]The peak regulation and heating capacity of the unit can be effectively improved by coupling the storage water tank with the unit,and the operation mode can be determined according to the actual heat load data to maximize the benefit.[Conclusions]This method has guiding significance to the operation strategy of the unit.
