Blockchain has become the technology enabler in delivering modern Smart Grid 2.0 functionalities. Many services including Peer-to-Peer energy trading, distribution network management, financial settlements, and energy data management are catered through blockchain-enabled platforms. However, areas such as service quality-based pricing strategies, supply–demand balancing in distribution system to attain enhanced reliability and consumption-oriented rewarding mechanisms need improving in order to achieve the full benefits of the envisaged grid architecture. In response, this study proposes a novel Blockchain-as-a-Service for Energy Trading (BaaSET) platform, which offers reputation-based services, executed through smart contracts for smart grid applications. Reputation-based grid operations are automatically executed through smart contracts deployed onto a blockchain. The reputation is estimated using power quality and reliability indices, obtained through grid measurements. Further, tests have been conducted to evaluate the associated latency and the implementation cost of the proposed blockchainized service architecture. Test results signify the performance to be comparatively better considering the state-of-the-art. The results further suggest alternatives to improve the scalability of the architecture, to cater the increasing number of stakeholders in the SG 2.0 environment.

利用区块链声誉管理服务增强智能电网 2.0 应用程序的性能

区块链已成为提供现代智能电网 2.0 功能的技术推动者。包括点对点能源交易、配电网络管理、财务结算和能源数据管理在内的许多服务都是通过区块链支持的平台提供的。然而，诸如基于服务质量的定价策略、配电系统中的供需平衡以提高可靠性以及以消费为导向的奖励机制等领域需要改进，以便实现设想的网格架构的全部优势。为此，本研究提出了一种新颖的能源交易区块链即服务（BaaSET）平台，该平台提供基于声誉的服务，通过智能电网应用的智能合约执行。基于声誉的网格操作通过部署在区块链上的智能合约自动执行。声誉是使用通过电网测量获得的电能质量和可靠性指数来估计的。此外，还进行了测试来评估所提出的区块链服务架构的相关延迟和实施成本。测试结果表明，考虑到最先进的技术，性能相对更好。结果进一步提出了提高架构可扩展性的替代方案，以满足 SG 2.0 环境中越来越多的利益相关者的需求。
