For example, the regional power information is V, the corresponding regional power utilization time is B, when the preset power grid maintenance range is P, if B is located in P, the current power supply mode is kept unchanged, and after the power grid maintenance is completed, the power supply mode is switched to the power grid with you; otherwise, switching to a new energy power supply mode for power supply operation.
