新型电力系统视角下建筑侧蓄冷再认识
Reunderstanding of cool storage systems in buildings from perspective of new power systems
摘要：
新型电力系统是实现碳中和目标的关键,既包含电源结构调整为以新能源为主体,更需要解决灵活调节、供需匹配等方面的难题,需要电源侧、电网侧、用户侧多种储能作为支撑。建筑等用户侧的蓄冷是用户侧重要的蓄能手段,在传统空调系统中多根据峰谷电价、建筑空调负荷需求进行系统设计、运行。在新型电力系统建设需求下,建筑侧蓄冷有何新的要求?面向新型电力系统中用户侧储能、协助电力系统供需匹配调节的新需求,建筑侧蓄冷应如何进行设计、运行?用户侧蓄冷与蓄电之间的联系和区别如何?本文将对上述问题进行探讨,以期为新型电力系统的构建及建筑等用户侧蓄冷方式的合理设计、运行提供有益参考。
Abstract：
The new power system is the key to achieving the goal of carbon neutrality. It not only includes the adjustment of the power supply structure to the new energy as the main, but also needs to solve the problems of flexible adjustment, supply and demand matching, etc., which requires the support of a variety of energy storage at the power supply side, the grid side and the user side. Cool storage in building and other user-side is the common energy storage means that users focus on. In the traditional air conditioning system, the system design and operation are mostly carried out according to the peak and valley electricity prices and the demand of building air conditioning load. Under the requirement of new power system construction, what are the new requirements for the cool storage of the building side? Facing the new requirements of user-side energy storage in the new power system and assisting the supply and demand matching adjustment of the power system, how should the design and operation of building side cool storage be carried out? What are the connections and differences between user-side cool storage and power storage? In this paper, the above problems will be discussed in order to provide effective guidance for the construction of new power systems and the reasonable development of user-side cool storage in buildings.
