Peer-to-Peer Energy Market Place Powered by Blockchain and Vehicle-to-Grid Technology

The concept of peer-to-peer energy trading became popular with the increase of local energy production and use of renewable energies. Based on a sharing economy, this framework allows energy trading between households, bringing flexibility and decreasing the dependency on energy providers. In parallel, the increasing adoption of electric vehicles and the development of vehicle-to-grid (V2G) technology open new ways to store, transport and deliver renewable energy. V2G-enabled cars could contribute to the flexibility of peer-to-peer energy marketplaces. Our physical demonstrator illustrates the benefits of V2G-enabled vehicles in the context of local energy marketplaces in terms of economical gain, overall power balancing and consumed renewable energy rate. The demonstrator is composed of smart contracts implementing such marketplace running on a local Ethereum blockchain deployed on Raspberry Pis, autonomous agents simulating the energy consumption and production behavior of 4 households as well as their buying/selling behavior, and finally a V2G car whose behavior is controlled by a user through a tablet.
