Smart grids play an ultimate role in building a modern and sustainable society. It integrates numerous smart energy devices through the Internet and enhances the efficiency of renewable energy resources. It enables two-way communications among the consumers and providers to efficiently deliver and manage green energy resources.
  However, security is a major concern of smart grid networks in which large connections are accomplished through centralized servers. The blockchain model promotes the smart grid technology into a decentralized distributed model with high security. Through the blockchain model, the smart grid accomplishes the following facilities that are,
   •  Decentralization
   •  High Scalability
   •  Creating a trustless but secure environment
   •  Immutability
   •  High transparency and audit ability
   •  Deployment of secure scripts
   •  Automaticity
  Different use cases of blockchain technology in smart grids are as follows.
   •  Peer to Peer Trading infrastructure
   •  Smart Metering Networks
   •  Power Generation and Distribution
   •  Smart Grid Equipment Maintenance
   •  Energy Trading in electric vehicles
