Abstract

A smart grid is an automatic, flexible, and sustainable system integrated with communication and information technologies within the energy sector. It dynamically manages energy flow and provides a high-quality energy network by enabling real-time, bidirectional information transfer from energy production to consumption. Among its goals are the efficient use of energy and the integration of renewable energy sources. According to NIST standards, it encompasses seven main domains: generation, transmission, distribution, consumption, service provider, marketing, and operations. Consumption areas, such as home and industrial area networks, can be exposed to various attack vectors due to their complex structures. Traditional security methods may be insufficient against new-generation cyberattacks and zero-day attacks. Therefore, within the scope of this study, a blockchain-based secure communication system was designed to protect consumers against cyber threats. The aim was to enhance data communication security using blockchain technology. The data obtained from the smart grid was first stored in a .txt file and then integrated into the blockchain using IPFS technology. Subsequently, we reviewed the information by examining the data on the blockchain. In the first phase of our project, we created a smart contract using the Solidity language and established a connection via the Ethereum virtual machine to transfer the data. However, due to the excessive amount of data, adding data to the blockchain through Solidity became challenging. Therefore, we used this method solely for data verification purposes. The data transfer was successfully completed using IPFS technology.
