Peer-to-peer multi-energy trading in a decentralized network: A review
Abdul Haseeb Tariq, Uzma Amin
Abstract
Peer-to-peer (P2P) electricity trading has received a lot of attention in the last decade and recently there has been growing interest in the evaluation of market design, classical methods, and novel approaches for multi-energy trading. The existing literature only focused on electricity/electric-gas/electric-heat networks. Therefore, a comprehensive analysis of P2P multi-energy trading (P2P-MET) in a decentralized network is required for the multi-energy like electricity, hydrogen gas, and heat all in one framework for a sustainable future. This review study aims to provide an in-depth understanding of P2P-MET in a decentralized network including layers-defined multi-source network configurations, trading platforms, classical methods, novel approaches, and mechanisms. Considering MET, the rising number of prosumers take advantage of the opportunity and make this complicated decentralized network more complex. To handle the network complexities, smart contracts using distributed ledger-based blockchain, novel algorithm-based game theory, and some other approaches are reviewed. Furthermore, this review study covers the limitations, challenges, opportunities, and benefits of P2P-MET as well as current trends and future directions for a better understanding of the readers. It concludes that P2P-MET using blockchain/game theory in decentralized networks is alternatively better and more secure. • An overview of P2P multi-energy trading (MET) reviewed in a decentralized network. • This paper presents classical methods and core approaches for P2P-MET. • Numerous pilot and under-developed projects implemented globally are reviewed. • Simulating tools commonly used by researchers for P2P-MET are briefly discussed. • Current trends and future directions are reviewed for P2P-MET sustainable future.
