摘　　要：直流供电与交流供电相比,具有供电效率高、线损少、安全可靠性高等优点,而且方便与光伏发电、蓄电池等直流电源结合,减少逆变损失和逆变器硬件成本,实现电力负荷的移峰填谷,对降低电网装机容量和初投资成本、减少电网低负载运行时间、提高电网效率等具有重要作用,因此直流供电及蓄电与智能微网整合是建筑供电系统的发展方向。本文讨论了建筑直流供电及蓄电系统的优化设计、优化运行策略、直流供电与交流供电的实验对比、仿真对比,并在实际建筑中进行了示范应用,展示了直流供电及蓄电系统的优势。Compared with AC power, the DC power has the advantages of high power supply efficiency, low line loss, high reliability, etc. Further, DC power is more convenient to connect with PV power generation and batteries without needing DC/ AC inverter loss and hardware cost. The DC power supply and electricity storage can also achieve electricity demand shift, which can benefit much to the grid by decreasing required capacity and investment cost, reduce the period of partial load operation and so that improve the grid efficient. Therefore, DC power and electricity storage and its integration with smart grid will be development trend of building energy system. This paper discusses the optimal design and optimal operation strategies of the DC power supply and electricity storage in buildings. Experiment and simulation comparison between the DC power supply and AC power supply are conduct. The demonstration of the DC power supply and electricity storage system in a building is introduced as well to prove its advantages.
