摘　　要：介绍光电建筑的供电系统及储能系统,并以采用光伏直流供电的光电建筑在典型运行日的运行数据为例进行了分析。结果显示,在单日典型时段,根据当地峰谷电价时间分布,23:00至次日7:00采用的是市政AC/DC供电。当光伏电力不足以满足负荷需求时,蓄电池可以补充不足的部分。16:00后,光伏供应持续低于负荷功率,蓄电池始终处于放电状态,直至达到荷电下限,之后转为使用市政供电。在该运行日,发电出力达到了最大化,并实现了就地消纳。将储能与低压直流电应用到光电建筑中,能够实现多种效益,包括有效抑制负荷和发电的功率波动、实现能量时移、削峰填谷、就地消纳,从而提升电能的利用效率。Introducing the power supply system and energy storage system of photovoltaic buildings,and analyzing the operating data of photovoltaic buildings using photovoltaic DC power supply on typical operating days.The results show that during typical daily periods,according to the distribution of local peak and valley electricity prices,municipal AC/DC power supply is used from 23:00 to 7:00 the next day.When the photovoltaic power is insufficient to meet the load demand,the battery can supplement the insufficient part.16:After 00,the photovoltaic supply continues to be lower than the load power,and the battery remains in a discharged state until it reaches the lower limit of charge,after which it switches to using municipal power supply.On that operating day,the maximum power generation output was achieved and on-site consumption was realized.Applying energy storage and low-voltage direct current to photovoltaic buildings can achieve various benefits,including effectively suppressing power fluctuations in load and generation,achieving energy time shift,peak shaving and valley filling,and on-site consumption,thereby improving the utilization efficiency of electrical energy.
