A survey on blockchain‐enabled smart grids: Advances, applications and challenges

Abstract Electric power grid infrastructure has revolutionized our world and changed the way of living. So has blockchain technology. The hierarchical electric power grid has been shifting from a centralized structure to a decentralized structure to achieve higher flexibility and stability, and bloc...
