An Atomic Swap Approach for P2P Electricity Trading Including Transmission Loss

As a blockchain application and method to realize more eco-friendly energy use, peer-to-peer(P2P) electricity trading through Ethereum-type blockchain is a considerable solution. Sustainable Development Goals include ecological energy provision and efficiency. P2P electricity trading can contribute to achieve this goal because surplus electric power of prosumers is generated from photovoltaic solar panels. In this research, Ethereum blockchain is used to administer the P2P trade. By preparing several blockchains and including a system of atomic swap, P2P trading can be carried out locally and widely. To prioritize local P2P trading, transmission loss will be minimized. Atomic swap can be included conventional blockchains which are used to realize P2P electricity trading, so this system will enhance flexibility of this research. To check the effect compared to current electricity trading systems, some patterns of market systems or algorithms like single-price auction and continuous session are set. In addition to ecological effect, economically positive effect is sought.
