Abstract: The new emerging idea of energy router and energy blockchain network (EBN) is gaining remarkable attention due to various applications and innovative solutions for efficient energy trading. However, the implementation of the EBN raises multiple challenges such as lack of power loss consideration and congestion management, insufficient computing, and higher transaction costs. This paper introduces a new energy trading approach to counter energy trading challenges effectively and perform optimal energy trading. The proposed systematic design was divided into four steps which execute (i) forming trading pairs through a two-stage Stackelberg game model, (ii) checking security by using the characteristics of directional power flow, (iii) congestion management through the minimum loss multi-path power transmission scheme, (iv) forming smart contracts, and settling transactions. The performance of the proposed framework is verified using 13 nodes EBN implementation, where the results obtained demonstrate accurate energy trading, balanced trading prices, even in congestion conditions.

Keywords: energy blockchain network; EBN; energy router; energy trading; power transactions; congestion management; Stackelberg master-slave game mode.
