Small scale peer-to-peer electricity trading through Ethereum Blockchain

This paper discusses a method to realize peer-to-peer electricity trading. In peer-to-peer trading, prosumers, consumers who can generate electricity by themselves, sell other prosumers surplus electricity. To practice this trading, electric utility might consider transmission loss and storage batteries. Also, there should be some kind of medium. In this research, electricity trading simulations with and without storage batteries will be executed, while using blockchain as a medium. Price of electricity is decided from amount of electricity and transmission loss. About 10 prosumers in small area are set as nodes of peer-to-peer electricity network. As a result, transmission loss in a small scale does not affect electricity trading so much and storage batteries prevented peer-to-peer trading.
