Power quality is a critical aspect of power distribution networks, and ensuring its improvement is essential for reliable and efficient electricity supply. This paper proposes a novel approach to enhance power quality by implementing a blockchain-based communication framework in remote terminal units (RTUs). The use of blockchain technology offers advantages such as data integrity, security, decentralized network management, and automation through smart contracts. By leveraging these capabilities, the proposed framework aims to enable efficient communication and coordination among RTUs, leading to improved fault detection, isolation, and restoration processes. Additionally, the transparency and auditability provided by blockchain technology facilitate regulatory compliance and accountability in power distribution networks. However, challenges related to computational and energy costs, as well as scalability, must be carefully evaluated before implementing the blockchain-based framework. Through this research, a deeper understanding of the potential benefits and considerations of utilizing blockchain in RTUs for power quality enhancement can be gained, paving the way for future advancements in power distribution network management.
