Micro-electricity centralized control power supply system for supplying power by multiple power supplies

The invention discloses a micro-power centralized control multi-power supply power supply system. The system comprises a distribution line power data acquisition module, a micro-power centralized controller, a power supply switching module, a commercial power supply module, a battery energy storage power supply module and a photovoltaic power supply module. The micro-electricity integrated controller is connected with the distribution line power data acquisition module, the power supply switching module, the commercial power supply module, the battery energy storage power supply module and the photovoltaic power supply module, and the distribution line power data acquisition module acquires distribution line power data and transmits the data to the micro-electricity integrated controller. The micro-electricity centralized controller generates a power supply switching control signal based on the power data information of the distribution line and transmits the power supply switching control signal to the power
