Blockchain-Based Energy Trading in ElectricVehicle Enabled Microgrids

This article presents a blockchain-basedscheme for energy trading between electric vehicles(prosumers) and critical load (consumer) in a mi-crogrid. Unlike traditional wholesale energy mar-kets where retailers sell energy to consumers, ourproposed model directly connects prosumers withconsumers to exchange energy. We exploit blockchaintechnology to establish a trusted energy tradingecosystem. The article provides an overview of theblockchain enabled architecture that facilitates peer-to-peer energy trade in a logical network, using thebuilding blocks provided by 5G network. An energytrading prototype is developed to remotely monitorenergy trading activities between prosumers and con-sumer, using graphical user interface. Experimentalresults based on a real map of Paisley illustrate thatthe energy trading system is effective in finding,associating and routing prosumers to consumers,while protecting privacy of entities. Numerical resultsshow a favorable performance of our optimizationmodel in comparison to traditional frameworks.
