摘　　要：利用供暖、通风和空调系统与建筑的耦合热惰性提供需求响应资源是一种经济实用的方法,尤其是具有主动储能系统的建筑物,具有更大的需求响应潜能。首先搭建仿真平台并验证了其准确性,然后从建筑和空调的被动储能以及蓄热罐的主动储能两个方面进行研究,采用了预冷、温度重置以及启停制冷机组3种策略的灵活组合,分析了建筑和空调系统、蓄热罐的需求响应潜力。结果表明,该策略对于短期(0.5h)和长期(2.5h)的需求响应均有效:对于短期需求响应计划,利用建筑和空调系统本身的热惰性就可以满足;对于长期需求响应计划,需用到主动储能技术满足室内热舒适要求。It is an economic and practical method to provide demand response resources by using the coupled thermal inertia of heating,ventilation and air conditioning systems(HVAC)and buildings.Buildings with active energy storage systems have great-er potential to reduce electrical load during demand response.A simulation platform is built and its accuracy is verified,the re-search is carried out from two aspects:passive energy storage of buildings and air-conditioning and active energy storage of heat storage tank.The flexible combination of three strategies of precool-ing,temperature reset and shutdown of refrigeration unit is adopted to analyze the demand response potential of buildings,air-condi-tioning and heat storage tank.The results show that this strategy can meet both short-term(0.5 h)and long-term(2.5 h)demand re-sponse.For short-term demand response plans,the thermal inertia of building and air-conditioning system can be used.For long-term demand response plan,active energy storage technology is needed to meet indoor thermal comfort requirements.
