description The invention discloses a low-voltage intelligent power distribution area power supply system, which comprises a monitoring system, a bidirectional inverter, an isolation transformer, a grid-connectedand off-grid switching cabinet and an energy storage unit, the monitoring system is electrically connected with the energy storage unit, the bidirectional inverter and the grid-connected and off-gridswitching cabinet. The bidirectional inverter is electrically connected with the power grid end and the input end of the isolation transformer. The isolation transformer is electrically connected with the grid-connected and off-grid switching cabinet; the grid-connected and off-grid switching cabinet is electrically connected with the load end; and the energy storage unit is used for providing sustainable electric energy for the transformer area when the power grid fails, and is electrically connected with the bidirectional inverter. According to the scheme, when the battery module has a charging and discharging fault
