The invention discloses a low-carbon intelligent direct-current power supply system, which is characterized in that a first direct-current circuit breaker is arranged between two control buses, the connection structures of the two control buses are the same, a direct-current isolation switch is arranged between the control buses and a branch line, an AC/DC switcher is connected with the branch line, and a direct-current circuit breaker is arranged between a storage battery pack and the branch line; and the storage battery pack is connected with the photovoltaic array device and is provided with a direct-current circuit breaker. According to the low-carbon intelligent direct-current power supply control method, the low-carbon intelligent direct-current power supply system is adopted, and the normal operation stage and the AC/DC switcher fault stage are controlled. The method has the advantages that under the condition that safe and reliable power supply of the direct-current load is guaranteed, consumption max
