In this way, to avoid the possibility of an emergency power-off situation due to self-protection of the mains power terminal 202, an emergency alarm can be issued through wired or wireless to allow the user to have a buffer time to adjust the load power.

It should be noted that if the mains power terminal 202 is powered off, the power can be provided by the battery power terminal 201, but the battery power terminal 201 is set to discharge at most to a discharge upper limit, and a warning is recorded and issued.

For example, the contracted capacity can be set The upper limit of the power supply to the user is 180KW, and the electric power of the load target can be set to 144~180KW. In addition, the power consumption of the load target can also be adjusted according to the optimized power consumption of the load target obtained from historical data related to the past power consumption of the load system 900. In addition, the power supply capacity of the secondary battery at the battery power terminal 201 can also be increased to further improve power efficiency.

Next, in step S105, the central computing management and control system 10 is used to obtain real-time monitoring data of the mains power terminal 202, the load system 900, and the battery power terminal 201 through the power supply monitoring and adjusting system 30. For example, the real-time monitoring data may include real-time voltage, current, power, temperature, time, etc. of the mains power terminal 202, the load system 900, and the battery power terminal 201. Moreover, the real-time monitoring data can be transmitted to the central computing management and control system 10 through wired or wireless means.

Then, in step S107, the central computing control system 10 is caused to determine whether the actual load power of the load system 900 is higher than the set load target power according to the obtained real-time monitoring data.
