An electric energy metering data verification system and method for electric power retail market

Abstract

The invention discloses an electric energy metering data verification system for an electric power retail market. The system comprises an intelligent electric energy meter, an acquisition terminal, anacquisition master station, an electricity selling main body and a data verification master station, and the intelligent electric energy meter, the acquisition terminal, the acquisition master station and the electricity selling main body calculate verification codes corresponding to electric energy metering data acquired at the end of a preset verification period through a chain algorithm; The data verification master station receives the electric energy metering data from the power client side, and calculates a verification code corresponding to the electric energy metering data collected at the end of a preset verification cycle by adopting a chain algorithm; And the check codes calculated by the intelligent electric energy meter, the acquisition terminal, the acquisition master station and the electricity selling main body is compared with the check codes calculated by the intelligent electric energy meter, the acquisition terminal, the acquisition master station and the electricity selling main body to judge whether the electric energy metering data is tampered. The invention also discloses a corresponding method. A data verification master station is introduced, electric energy metering data verification values are calculated in all links of the data verification master station and data transmission, and tampering of the electric energy metering data in which link is judged by comparing the verification values.

Description

technical field [0001] The invention relates to an electric energy metering data verification system and method for an electric power retail market, and belongs to the technical field of electric energy metering. Background technique [0002] In the future, with the continuous increase in the number of electricity sales companies entering the market, the continuous increase in the proportion of cross-regional transactions of renewable energy power generation, and the gradual opening of the spot market, trading entities will become more diversified, and the types of transactions and transaction cycles will become more flexible and changeable . The granularity of the time-of-use metering data provided by the metering system is getting finer and finer, the amount of data is getting bigger and bigger, and there are more and more participants in the electricity market. As an important module of the power market operation support system, the electric energy metering system must n...
