Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SCADA, IEC 61850, and IEEE 1547 smart grid control systems are vulnerable to cyber and physical attacks, lacking secure and automated control mechanisms for distributed energy and computation systems, which hampers the reliability and efficiency of energy delivery.
Innovation Solution
The TransActive Grid (TAG) system implements a decentralized, market-based, peer-to-peer control and settlement network using blockchain technology for secure, autonomous control of smart grid devices, enabling self-executing contracts and tokenization of energy and computation values, ensuring secure, transparent, and auditable transactions across a distributed network.

Engineering Contradiction Analysis
1Extent of automation
If current SCADA, IEC 61850, and IEEE 1547 smart grid control systems are used, then automated control of distributed energy systems is achieved, but vulnerability to cyber and physical attacks increases
Solution Approach 1:
The patent segments the centralized control architecture into distributed autonomous nodes (smart appliances, energy systems, computation systems) that each operate independently with local decision-making capabilities. This segmentation eliminates the single point of failure in centralized SCADA systems and distributes security requirements across multiple independent entities, thereby maintaining automation while improving resilience against cyber and physical attacks.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer that enables secure peer-to-peer transactions and consensus among distributed nodes without requiring centralized control. This intermediary provides cryptographic security, immutable transaction records, and decentralized consensus mechanisms that protect the system from attacks while enabling automated control functions.
2Reliability
If decentralized peer-to-peer control is implemented, then security and resilience are improved, but system complexity increases
Solution Approach 1:
The patent implements universal smart contracts and standardized communication protocols that enable diverse distributed nodes (energy systems, computation systems, smart appliances) to interact through common interfaces. This universality simplifies the decentralized architecture by providing reusable templates for transactions, consensus mechanisms, and interoperability, thereby reducing the effective complexity despite the distributed nature of the system.
3Reliability
If blockchain-based distributed consensus is used, then transaction security and auditability are enhanced, but computational overhead increases
Solution Approach 1:
The patent implements a hybrid consensus approach where not all nodes participate in every consensus decision. Instead, the system uses a combination of lightweight validation for routine transactions and more intensive consensus mechanisms only when necessary (e.g., for critical energy transactions or dispute resolution). This partial action approach maintains security and auditability while significantly reducing the overall computational overhead compared to requiring full consensus for all operations.
