Unless otherwise specifically stated, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which this invention belongs. The use of "including" or "comprising" and the like in this disclosure does not limit the presence or addition of any number, step, action, operation, component, element, and/or group thereof or does not preclude the presence or addition of one or more other different numbers, steps, actions, operations, components, elements, and/or groups thereof.

and S110, carrying out time synchronization on the server with the NTP time pair and the standard clock.
It should be noted that, since the electric quantity of the directly obtained Programmable Logic Controller (PLC) may be a daily electric energy generation amount or a total electric energy generation amount, the data is prone to be inaccurate. Therefore, the method of the embodiment is based on the operation on the server provided with the Network Time Protocol (NTP) Time pair, that is, the server with the NTP Time pair is synchronized with the local Time, and the daily power generation amount data on the NTP server is cleared to avoid the limitation of the PLC, so as to obtain the corrected daily power generation amount.
It should be further noted that NTP is a protocol for time synchronization of computers, which can synchronize the computer to its server or clock source (e.g. quartz clock, GPS, etc.), which can provide highly accurate time correction (less than 1 ms difference from standard on LAN and tens of ms on WAN), and which can prevent malicious protocol attacks by means of encrypted confirmation. Time is propagated on the level of the NTP server. All servers are classified in different layers (Stratum) according to distance from the external UTC source.
