Abstract
To further implement decentralized renewable energy resources, blockchain based peer-to-peer (P2P) energy trading is gaining attention and its architecture has been proposed with virtual demonstrations. In this paper, to further socially implement this concept, a blockchain based peer to peer energy trading system which could coordinate with energy control hardware was constructed, and a demonstration experiment was conducted. Previous work focused on virtually matching energy supply and demand via blockchain P2P energy markets, and our work pushes this forward by demonstrating the possibility of actual energy flow control. In this demonstration, Plug-in Hybrid Electrical Vehicles(PHEVs) and Home Energy Management Systems(HEMS) actually used in daily life were controlled in coordination with the blockchain system. In construction, the need of a multi-tagged continuous market was found and proposed. In the demonstration experiment, the proposed blockchain market and hardware control interface was proven capable of securing and stably transmitting energy within the P2P energy system. Also, by the implementation of multi-tagged energy markets, the number of transactions required to secure the required amount of electricity was reduced.
Highlights
To further implement decentralized renewable energy resources [1], blockchain based peer to peer (P2P) energy trading is a promising concept [2]
The system performance was verified by first checking that daily transactions were executed without any issues, and second analyzing issues in blockchain system operation
To further socially implement blockchain based P2P energy trading, a blockchain based P2P energy trading system which could coordinate with energy control hardware was constructed, and a demonstration experiment was conducted
Summary
To further implement decentralized renewable energy resources [1], blockchain based peer to peer (P2P) energy trading is a promising concept [2]. Many researchers have proposed and virtually verified blockchain system architectures, which could possibly realize this concept [9,10,11,12,13,14]. This trend is backed up with extensive consideration on social acceptance and policy adjustments as energy distribution being a social infrastructure which involves several stakeholder responses when trying to be updated [15,16,17,18,19]
