Usage of blockchain for peer-to-peer energy exchanges: design, simulation and recommendations

Energy communities and peer-to-peer energy exchanges are expected to play an important role in the energy transition. In this context, the blockchain approach can be employed to foster this decentralized energy market. Our goal is to determine the design that should allow a Distribution System Operator (DSO) to accept peer-to-peer energy exchanges based on a distributed ledger supported by the blockchain technology. To this end, based on simulation, we will evaluate several designs based on criteria such as the execution time to create a transactions block (also known as mining), the resilience of the consensus to approve a block, the energy required for the mining , scalability problems, etc. The structure of this paper is the following: 1) Introduction, 2) DSO Key requirements, 3) bridge the gap between physical world (power and energy) and the digital world, 4) evaluating of the different blockchain design, and 5) Recommendations and conclusion.
