摘　　要：近年来,空调负荷的急剧增长已经成为季节性电力紧张的最主要原因,利用空调需求响应策略,调整空调负荷对于实现电网削峰填谷有重要意义。以风机盘管加新风形式的空调系统为对象,建立其TRNSYS仿真模型,基于分时电价政策,针对温度再设需求响应策略进行研究,采用再次设定制冷区域温度和热舒适指标两种策略,对比其在需求响应期间的峰值负荷削减量和整体系统运行的费用。结果表明基于温度再设的需求响应策略峰期负荷转移率约为30.3%,基于热舒适指标控制的需求响应策略的峰期负荷转移率约为22.7%,然而,这两种策略并不能节省电费,因此,除了分时电价的优惠政策外还需要给予相应的激励措施。In recent years,the rapid growth of air-conditioning load has become the main reason for seasonal power shortage.Using air-con⁃ditioning demand response strategies to adjust air-conditioning load is of great significance for achieving grid peak reduction and valley fill⁃ing.Taking the air conditioning system in the form of fan coil units and fresh air as the object,the TRNSYS simulation model is estab⁃lished.Based on the time-of-use electricity price policy,the temperature reset demand response strategy is studied,and the refrigeration zone temperature and the thermal comfort index are two strategies which aim to compare the peak load reduction during the demand re⁃sponse period and the overall system operating costs.The results show that the peak load transfer rate of the demand response strategy based on temperature reset is about 30.3%,and the peak load transfer rate of the demand response strategy based on the thermal comfort index control is about 22.7%.However,two strategies cannot save electricity bills.Therefore,in addition to the preferential policies for time-of-use electricity prices,corresponding incentives must be given.
