Invention Reference Number
A secure, blockchain-enabled system improves the performance and reliability of electrical grids connected to customer-owned renewable energy sources. By managing power quality through automated smart contracts, the technology reduces energy losses while safeguarding critical grid control data. This solution addresses the growing challenge of integrating variable distributed energy resources without compromising operational stability or cybersecurity.
Description
This technology uses a secure, modular platform to manage data from protective relays at points where customer-owned renewable energy systems—such as wind or solar farms—connect to the main electrical grid. A blockchain-based distributed ledger records operational data and enforces smart contract rules to maintain desired power quality levels. The system incorporates a protective “cyber guard” that monitors conditions and, if needed, automatically triggers breaker operations based on pre-defined parameters. By combining data integrity, decentralized trust, and automated control, the solution minimizes reactive power losses, improves grid efficiency, and ensures reliable operation under normal and abnormal conditions. The design supports integration with various distributed energy resources and enhances resilience against cyber and operational threats.
