可选地，作为本发明提供的能源消纳系统的一种具体实施方式，控制模块200根据实时电流电压信息控制第一变流器11、第二变流器12、第三变流器13、第四变流器14的工作状态，可包括：
当能源消纳系统的当前工作模式为第一工作模式时，若实时电流电压信息显示第三馈线的端口电压小于第一预设电压值且第一馈线的供电电流大于第一预设电流值，则控制第一工作模式下的可用变流器工作在整流模式，由第一馈线和第一工作模式下的可用馈线向第三馈线供电。其中，第一工作模式下的可用变流器为第二变流器12和/或第四变流器14，第一工作模式下的可用馈线为第二馈线和/或第四馈线。

在本实施例中，各条馈线之间的负荷切换是通过控制模块200采集的电压电流信息触发的。本实施例中的第一工作模式中直流即插端口可以不接入外部设备，也可接入外部设备后控制各个外部设备截止。
本发明实施例提供的控制模式也可以描述为：能源消纳系统工作在第一工作模式(也即通过第一馈线向第三馈线供电)，若控制模块200采集的电压电流信息显示第一馈线无法满足第三馈线的负荷需求，则通过控制模块200控制第一工作模式下的可用变流器(也即第二变流器12和/或第四变流器14)工作在整流模式，由第一馈线和第一工作模式下的可用馈线(也即第二馈线和/或第四馈线)向第三馈线供电。其中，可用馈线包括至少一条馈线，例如本实施例中第一工作模式下的可用馈线可以为第二馈线，可以为第四馈线，也可以为第二馈线和第四馈线。
在本实施例中，控制模块200还可以根据上层调度信息控制第一变流器11、第二变流器12、第三变流器13、第四变流器14的工作状态。例如，能源消纳系统的当前工作模式为：第一变流器11工作在整流模式、第三变流器13工作在逆变模式、第二变流器12和第四变流器14截止，此时由第一馈线向第三馈线供电。若此时控制模块200接收到上层调度信息，该上层调度信息指示由第一馈线向第二馈线和第三馈线供电，则在能源消纳系统的当前工作模式的基础上，可通过控制模块200控制第二变流器12工作在逆变模式，来实现第一馈线、第二馈线和第三馈线的互联。

在本实施例中，若第二馈线的短路故障消除，则控制模块200可根据实时的实时电流电压信息重新进行各条馈线之间的负荷切换。
在本实施例中，若故障检测结果显示某一馈线的端口出现过负荷或短路时，则在能源消纳系统的当前工作模式的基础上，控制将过负荷或者短路的馈线的一部分负荷转供至另一馈线上，从而实现负荷平衡。本发明实施例可根据实际的电压电流信息进行任意控制模式的自主切换。
