Design and Validation of a Blockchain-Based Distributed Power Trading System For Sustainable Biotechnological Manufacturing And Commercialization

Abstract

Efficient and sustainable energy management is critical for biotechnological manufacturing and commercialization, where stable power supply and cost optimization directly impact production processes. Traditional electricity trading systems often face challenges such as high resource consumption and low transaction settlement efficiency, which can hinder the operational sustainability of biotechnological facilities. To address these issues, this study presents a blockchain-based distributed power trading system designed using Hyperledger Composer (HC) and driven by a buyer’s game theory strategy to optimize energy trading processes in biotechnology-related operations. The proposed trading strategy allows buyers to reach equilibrium states with minimal iterations, effectively reducing both individual electricity costs and total system costs. Performance validation through simulation experiments demonstrates that the system maintains an average query operation delay of 0.5 seconds at sending rates between 100 TPS and 200 TPS, with throughput peaking at 100% efficiency up to 300 TPS. Beyond 200 TPS, the average delay increases significantly, reaching 12.74 seconds at 350 TPS, although throughput remains consistently higher compared to the Ganache system. Notably, the proposed system achieves a minimum delay of 0.17 seconds, significantly outperforming the comparison system in both response speed and fault tolerance. The combination of high throughput, low latency, and robust fault tolerance makes this blockchain-enabled distributed power trading system highly suitable for energy-intensive biotechnological manufacturing environments. By ensuring secure, efficient, and cost-effective power trading, this system supports the reliable operation and sustainable commercialization of biotechnological innovations, contributing to resilient energy ecosystems essential for the biotechnology industry’s growth in smart city infrastructures.
