The extension of emerging renewable energy sources such as wind and
water turbines, solar panels, and the increasing usage of electric
vehicles requires the supply and distribution of energy in a small
device on local scale and it has created new methods of supplying and
selling electricity. Middle buyers and end users can obtain the local
energy with the peer-to-peer trading method in this large and
hierarchical market. This method enables market to manage and exchange
the electricity between major suppliers and medium and local levels.
Blockchain technology is developing in peer-to-peer exchange of
electricity and acts as a reliable, efficient and safe technology in the
electricity trading market. In this method, while preserving the privacy
of electricity users, by using smart contracts and by removing
intermediaries in the energy supply and demand market, direct commercial
interactions between energy suppliers and consumers are done. The
Blockchain technology, while creating trust between the parties in the
energy market, reduces the cost of electricity trading and increases its
scalability with using the intermediate energy aggregators. In this
research, the blockchain-based model, is presented for distribution and
peer-to-peer transactions in the energy market. The suggested model
provides the possibility of registration low-cost instant transactions
at the power grid in any specific period of time. The above method,
unlike periodic payments, provides immediate access to bills and small
payments. Since the transactions outside the blockchain chain are not
recorded, this system guarantees its honest and independent operation
without fraud and failure. The smart contract method based on
blockchain, reduces the transaction fees and speeds up electricity
trading.
