为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面结合附图和实施例，对本申请的具体实施方式作进一步详细描述。以下实例用于说明本申请，但不用来限制本申请的范围。
如图1所示，本申请实施例提供的空调系统供电控制方法包括：
S10：在空调器的电流高于电流阈值的情况下，若空调器的电压下降值大于预设值，控制太阳能储能装置和空调器的外接电源向空调器供电。
其中，太阳能储能装置与空调器电连接。
太阳能储能装置用于将太阳能转化成电能储存。太阳能储能装置包括太阳能板和储能部件，太阳能板安装于光照充足的室外环境中，将太阳能转化为电能，储能部件利用太阳能板产生的能量充电，并在特定条件下为空调器供电。
当电网提供的电压降低时，空调器处于欠压补偿的状态，空调器的电流会相对增大，若长期以此状态运行，会使空调器内部温度过高，造成停机。
而本申请实施例中，在空调器的电流高于电流阈值的情况下，获取空调器的电压下降值，若空调器的电压下降值大于预设值，则控制太阳能储能装置和空调器的外接电源共同向空调器供电，对空调器的电压进行补偿，有效降低电压波动对空调器带来的损耗，提高空调器的工作效果。
其中，电流阈值为能使空调器保持正常运行的最大电流，空调器的不同模式或设定温度具有不同的电流阈值。当空调器在运行时的电流超出电流阈值时，空调器可能处于非正常工作状态，影响工作效果，甚至产生非正常损耗。
预设值为能使空调器保持正常运行的最大电压波动值，当空调器的电压下降值大于预设值时，空调器的电压波动较大，有可能会影响空调器元器件的运行。
本申请实施例提供的空调系统供电控制方法，可以实时获取空调器的电流，也可以每间隔一段时间获取一次空调器的电流，例如每隔1min获取一次空调器的电流，判断其是否超出电流阈值。
在空调器的电流高于电流阈值的情况下，通过比较空调器的电压下降值和预设值，判断空调器的电流变化是否由电压波动引起，若空调器的电压下降值大于预设值，则对空调器的电压进行补偿，由太阳能储能装置和空调器的外接电源共同向空调器供电。
在另一个实施例中，在空调器的电流高于电流阈值的情况下，若空调器的电压小于电压阈值，控制太阳能储能装置和空调器的外接电源向空调 器供电。通过比较空调器的电压和电压阈值，判断空调器的电流变化是否由电压波动引起。其中，电压阈值为能使空调器保持正常运行的最小电压，当空调器的电压小于电压阈值时，空调器的电流变化是由电压波动引起的，此时对空调器的电压进行补偿，由太阳能储能装置和空调器的外接电源共同向空调器供电。
本申请实施例提供的空调系统供电控制方法，通过在空调器的电流高于电流阈值的情况下，确定空调器的电压下降值大于等于预设值，并控制太阳能储能装置和空调器的外接电源向空调器供电，增加了空调器的电能来源，对空调器的电压进行了补偿，降低了电网电压波动对空调器带来的影响，使空调器在非正常的工况下仍能正常运行。
本申请实施例提供的空调系统供电控制方法，可以控制太阳能储能装置和空调器的外接电源向相同的元器件供电，也可以控制太阳能储能装置和空调器的外接电源分别向不同的元器件供电。
例如，在一个实施例中，如图2所示，控制太阳能储能装置和空调器的外接电源向空调器供电，包括：
S11：在空调器的电压小于预设电压的情况下，控制太阳能储能装置向空调器的用电部件供电，并控制空调器的外接电源向空调器的压缩机供电。
其中，用电部件包括空调器的每一用电负载，例如压缩机、风机、电机等元器件。
预设电压为预先设定的电压值，当空调器的电压小于预设电压时，空调器处于低压运行状态，空调器的供电不足。
在空调器的电压下降值大于预设值的情况下，将空调器的电压与预设电压比较，若空调器的电压小于预设电压，则控制太阳能储能装置向空调器的用电部件供电，而为了保证空调器的工作效果，控制空调器的外接电源仅向空调器的压缩机供电，降低对空调器制冷/制热效果的影响。也即，空调器的压缩机由太阳能储能装置和外接电源共同供电，而空调器中除压缩机以外的其他用电负载由太阳能储能装置供电。
并且，若空调器的电压小于预设电压，电压补偿需求量相对较高，因此控制空调器的外接电源仅向空调器的压缩机供电，有利于降低太阳能储 能装置的耗能速度，延长太阳能储能装置的使用时间，提高太阳能储能装置的供电效率。
当然，若空调器的电压小于预设电压，也可以控制太阳能储能装置仅向空调器的压缩机供电，控制空调器的外接电源向除压缩机以外的其他用电负载供电，能对空调器进行电压补偿即可。
进一步地，控制太阳能储能装置和空调器的外接电源向空调器供电，还包括：
S12：在空调器的电压大于等于预设电压的情况下，控制太阳能储能装置和外接电源向用电部件供电。
在空调器的电压下降值大于预设值的情况下，若空调器的电压大于等于预设电压，空调器的电压虽下降，但对空调器运行的影响相对较小，电压补偿需求量相对较低，所以太阳能储能装置的耗能也较低，因此控制太阳能储能装置和外接电源共同向空调器的所有用电负载供电，对空调器进行电压补偿。
进一步地，预设电压大于等于180V，且小于等于186V。例如，预设电压可以为180V、183V、186V等。
预设值大于等于10V，且小于等于15V。例如，预设值可以为10V、13V、15V等。
在一个实施例中，根据图3所示，空调系统在运行时，按照以下步骤进行空调系统供电控制：
步骤S20：判断空调器的电流是否高于电流阈值，若是，执行步骤S21，若否，执行步骤S22；
步骤S21：判断空调器的电压下降值是否大于预设值，若是，执行步骤S23，若否，执行步骤S22；
步骤S22：控制空调器按照当前线路继续运行；
步骤S23：判断空调器的电压是否小于预设电压，若是，执行步骤S24，若否，执行步骤S25；
步骤S24：控制太阳能储能装置向空调器的用电部件供电，并控制空调器的外接电源向空调器的压缩机供电；
步骤S25：控制太阳能储能装置和外接电源向用电部件供电。
利用以上流程，增加了空调器的电能来源，对空调器的电压进行了补偿，降低了电网电压波动对空调器带来的影响，使空调器在非正常的工况下仍能正常运行。
