A Data Trust Model Based on Alarms Considering EVs Participating in Market Transactions

Electric vehicles (EVs) have load and power source properties as mobile energy storage loads. Designing their participation in the electricity market to consume renewable energy efficiently is a highly challenging technical problem for achieving the green transformation of energy. This article first introduced the management mode and data communication method for EVs participating in market transactions. Due to the direct economic impact of data security, accuracy, and final quotation, a direct data trust model was designed for both senders and receivers based on data transmission frequency. Considering alarm information during transmission, a global data trust model for a small network on the transmission channel was designed to determine the accuracy of data transmission in the subsystem based on the probability of data tampering. Finally, the feasibility of the proposed model was verified based on real data from an EV charging station in a province.
