A Novel Power Market Mechanism Based on Blockchain for Electric Vehicle Charging Stations

This work presents a novel blockchain-based energy trading mechanism for electric vehicles consisting of day-ahead and real-time markets. In the market, vehicle users submit their bidding price to participate in double auction mechanism. Subsequently, smart match will be conducted by charging system operator, meet both personal interests social benefits. After clearing result, operator uploads contract made market blockchain. checks status submits updated results encourages participants pursue higher interests, addition rationally utilize unmatched achieve improvement welfare. Case studies are used demonstrate effectiveness proposed model. For buyers sellers who successfully total profit increase buyer seller 22.79% 53.54%, respectively, as compared without trading. With consideration welfare mechanism, peak load reduces from 182 146.5 kW, which is 19.5% improvement.
