Blockchain is a promising new technology that might significantly alter the electricity industry. In this scenario analysis, we investigate how blockchain technology may be used in advanced grid infrastructure. There are three main applications that we examine. Peer-to-peer energy trading may be made easier by the use of blockchain technology. Direct power sales and purchases between consumers may be made possible. This may improve grid performance and relieve the strain on centralised power sources. A distributed ledger for grid management is possible with the help of blockchain technology. In this method, all grid users would be able to trace transactions transparently and securely in real time. This has the potential to enhance the safety and stability of the grid. Using blockchain technology, smart contracts for demand response may be developed. In return for financial incentives, users might sign such contracts to promise to minimise their energy usage during peak demand times. This has the potential to increase system dependability and decrease grid strain. Finally, we draw the conclusion that blockchain technology may greatly enhance the efficacy, dependability, and safety of smart power grids. However, several obstacles must be removed before the electricity industry can fully embrace blockchain technology.
