Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current SCADA, IEC 61850, and IEEE 1547-based smart grid control systems are vulnerable to cyber and physical attacks, lacking secure and automated control of distributed energy and computation systems, and fail to effectively utilize computation as a resource for peer-to-peer transactions and value exchange.
Innovation Solution
A blockchain-based, decentralized network (TransActive Grid) for secure, autonomous control of smart grid devices, using self-executing contracts and a public ledger to facilitate peer-to-peer transactions and value exchange, ensuring cryptographically secure, decentralized operation and tokenization of energy and computation resources.

Engineering Contradiction Analysis
1Extent of automation
If centralized control systems (SCADA, IEC 61850, IEEE 1547) are used for smart grid control, then automation and control capability are improved, but vulnerability to cyber and physical attacks increases
Solution Approach 1:
The patent divides the centralized control system into multiple distributed nodes that operate autonomously. Each node maintains its own state and can make decisions independently, eliminating the single point of failure in centralized systems. The control function is segmented across the network, so that no single node holds complete control authority, thereby reducing vulnerability to attacks while maintaining automation capability.
Solution Approach 2:
The patent introduces a blockchain-based consensus mechanism as an intermediary layer between nodes. This mediator enables secure peer-to-peer transactions and state validation without requiring trusted centralized authorities. The consensus protocol acts as a neutral intermediary that coordinates actions across distributed nodes, providing security and reliability while preserving automation.
2Reliability
If distributed peer-to-peer control is implemented, then security and resilience are improved, but system complexity increases
Solution Approach 1:
The patent implements a universal blockchain consensus protocol that serves multiple functions simultaneously: security validation, state coordination, transaction mediation, and consensus achievement. This multi-functional approach reduces the need for separate specialized components, thereby managing complexity while providing comprehensive security and resilience across the distributed system.
Solution Approach 2:
The patent changes the fundamental parameter of trust from centralized authority to distributed consensus. By altering the trust model parameter, the system achieves security and resilience without requiring complex centralized management structures. The consensus mechanism parameters (such as validation rules and agreement thresholds) are designed to simplify node interactions while maintaining robust security properties.
3Productivity
If computation is treated as a resource for peer-to-peer transactions, then resource utilization efficiency is improved, but the need for secure transaction validation increases system complexity
Solution Approach 1:
The patent enables computation resources to serve themselves through automated market-based transactions. Nodes can offer their computation capacity as a resource and automatically engage in peer-to-peer transactions without manual intervention. The system self-regulates resource allocation through price signals and automated contracts, improving utilization efficiency while the blockchain consensus mechanism handles validation automatically, managing the complexity of transaction verification.
