A Mobile App for Blockchain-Based Peer-To-Peer Energy Trading for Distributed Energy Resources Participation

The increasing global concerns about energy and the environment have created a growing demand for integrating distributed energy resources (DERs) into existing electrical infrastructures. To achieve this, peer-to-peer (P2P) energy trading is considered as, a potential solution to optimize the use of DERs. The proposed approach uses a private blockchain that is based on proof of authority for energy trading. A double auction mechanism is utilized for trading, which includes a multi-phase system for market clearing. To balance the load demand and clear the market, a smart contract is coded using the solidity language. In this work, a Flutter-based Android app is introduced for P2P energy trading that is built on the blockchain system, and it fully utilizes information about the participating prosumers and consumers, along with their electricity price and quantity. The reliability of the developed Android app is verified by testing it for P2P energy trading in the 0.4-kV Microgrid setup at the Clean Energy Research Lab, Nanyang Technological University (NTU) Singapore.
