The power system still counts forward in the standby power supply state, and the actual power consumption needs to be subtracted by 2 times of the standby power consumption (i.e. the second power value) from the electricity consumption (i.e. the first power value) displayed by the electricity meter.

According to the power correction method based on the intelligent power utilization module, the intelligent power utilization module is added in the power utilization system, so that the power utilization error of the standby power supply or the emergency power supply after the standby power supply or the emergency power supply is started can be corrected; meanwhile, different correction algorithms can be set and switched according to the type of the ammeter, so that correction accuracy is ensured. Meanwhile, the intelligent power utilization module does not need to change the layout of the original devices when the intelligent power utilization system is modified, and only needs to be added when the intelligent power utilization module is opened, so that the construction is convenient and time-saving.
In another optional embodiment of the present invention, the step S206, after correcting the first electric quantity value according to the first electric quantity value and the second electric quantity value to obtain an actual electric quantity value, may further include the following steps:
S1, sending a correction instruction carrying the actual electric quantity value to a server, wherein the correction instruction is used for indicating the server to use the actual electric quantity value as an actual statistical value, and the actual statistical value indicates the electric quantity value of the power grid for actually supplying power to the power utilization system in the first time period.
According to an optional embodiment of the invention, in the intelligent electricity utilization system, data communication between the intelligent electricity utilization gateway and the intelligent electricity utilization module and between the intelligent electricity utilization module and the intelligent electricity utilization module can be realized through a wired mode and a wireless mode, wherein the wired mode mainly comprises a 485 communication mode, and the wireless communication mode mainly comprises Bluetooth communication; the intelligent gateway and the intelligent host are in wired communication mainly through 485 mode.
