The invention discloses an optical storage DC power supply system based on a coordination control device. The optical storage DC power supply system comprises a field equipment layer, a network communication layer and a station control management layer. The field equipment layer comprises a distributed photovoltaic power generation unit, a lead-acid battery energy storage unit and a load unit, wherein the distributed photovoltaic power generation unit and the lead-acid battery energy storage unit are accessed to a DC bus by means of a DC/DC converter. The network communication layer is equipped with the coordination control device, which acquires operation data of a grid-connected current transformer, the DC/DC converter and the load unit, packages the acquired data and uploads the data to a host server of the station control management layer, and performs remote metering, remote control and remote regulation on parameters of equipment of the field equipment layer through issuing messages. The distributed pho
