考虑主动储能的HVAC需求响应策略实验与模拟

为了增强电网的稳定性和充分利用集中式空调（HVAC）系统在夏季参与“削峰”需求响应的潜力，提出考虑主动储能的需求响应（DR）策略. 利用全尺寸变风量HVAC实验平台，对该策略与区域温度重设策略进行物理实验和TRNSYS仿真模拟. 结果表明，与区域温度重设（GTA）策略相比，主动储能策略能够在降低对用户热舒适度影响的同时为电网提供稳定的削峰负荷. 对于整个供冷季而言，相比所有天数均采用非储能常规运行策略，主动储能策略下空调系统节约一定的运行成本；相较于在DR时采用GTA策略且非DR时采用非储能常规运行策略，主动储能策略的节费优势更大.

HVAC demand response strategy experiment and simulation considering active energy storage

A demand response (DR) strategy which considers active energy storage was proposed in order to enhance the stability of the power grid and fully use heating, ventilation and air-conditioning (HVAC) system in the summer to participate in the "peak shaving" demand response. A full-scale variable air volume HVAC experimental platform was used to conduct physical experiments and TRNSYS simulations on the strategy and the regional temperature reset strategy. Results show that active energy storage strategy can provide stable peak load for the power grid while reducing the impact on users’ thermal comfort compared with the global temperature adjustment (GTA) strategy. For the whole cooling season, the air-conditioning system saved operation cost under the active energy storage strategy while non-energy storage conventional operation strategy was adopted all the days. Cost-saving rates were more obvious compared to the GTA strategy during DR and conventional operation strategy of non-energy storage during non-DR.
