摘　　要：为解决由热电联产机组热电耦合特性所引起的弃风现象,基于热负荷可调性,提出基于热网主动储热的综合能源系统运行优化策略。通过分析不同场景下机组输出功率、热网储热效果及等效热负荷变化情况,分别探究了热网被动储热和热负荷可调性对风电消纳和系统运行性能的影响。结果表明:热网被动储热和柔性热负荷都可以提高风电消纳水平,但后者要优于前者。此外,热负荷可调性在一定程度上可以实现热网储热的主动性。To overcome the wind power curtailment caused by the thermoelectric coupling characteristics of combined heat and power units,this paper proposes an operation optimization strategy for integrated energy systems based on active heat storage of heat-supply networks by utilizing adjustable heat load.By analyzing the variations in unit output power,the heat storage effect of the heat-supply system,and the equivalent heat load in different scenarios,the paper explores the influences of passive heat storage of the heat-supply system and adjustable heat load on wind power consumption and system operation performance,respectively.The results show that both passive heat storage of the heat-supply system and flexible heat load can raise the level of wind power consumption,although the effect of the latter measure is better than that of the former one.In addition,adjustable heat load can be leveraged for positive heat storage in the heat-supply network to a certain extent.
