Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliance of power grids on GPS signals for timekeeping poses significant cybersecurity risks, as these signals can be easily jammed or spoofed, leading to potential cascading faults and disruptions, such as the 2003 Northeast Blackout, which highlights the need for an approach to minimize cybersecurity and other risks.
Innovation Solution
A quantum-hardened power grid is developed using atomic clocks, quantum networks, and quantum sensors, which provide enhanced precision and resilience by integrating quantum technologies like cold atoms for sensing and computing, enabling precise timekeeping and synchronization, and employing quantum networks for secure communication and fault detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS signals are used for timekeeping in power grids, then time synchronization is achieved, but cybersecurity vulnerability increases
Solution Approach 1:
The patent introduces atomic clocks as intermediary devices that generate local time references, mediating between the need for precise time synchronization and the desire to eliminate GPS dependency. These atomic clocks serve as self-contained time sources that do not require external GPS signals, thereby resolving the contradiction by providing accurate timing without cybersecurity vulnerability.
Solution Approach 2:
The patent extracts the timekeeping function from the GPS system and relocates it to local atomic clocks within the power grid infrastructure. By taking out the time synchronization capability from the vulnerable GPS external system and embedding it in secure local devices, the solution eliminates the cybersecurity vulnerability while maintaining measurement precision.
2Reliability
If quantum technologies are integrated into power grids, then resilience and measurement precision are enhanced, but device complexity increases
Solution Approach 1:
The patent segments the power grid system into distinct functional modules: atomic clocks for timekeeping, quantum sensors for measurement, and quantum communication channels for data transmission. This segmentation allows each quantum component to be independently optimized and managed, reducing overall system complexity while enhancing reliability through specialized functions.
Solution Approach 2:
The patent employs quantum technologies that serve multiple functions simultaneously. For example, atomic clocks provide both precise timekeeping and serve as reference sources for synchronization across the grid. Quantum sensors can detect both electrical parameters and anomalies, providing multi-functional capabilities that enhance reliability without proportionally increasing complexity.
Data Source
AI summary
A quantum-hardened power grid includes grid nodes (e.g., power plants, renewable energy sources and substations) and transmission lines connecting the grid nodes. The grid nodes include stable quantum clocks that permit the power grid to continue operation in the event of downtime for a GPS or other external synchronization reference. Operation sans an external reference can be extended by synchronizing atomic clocks across grid nodes using a quantum network. The atomic clocks can be used with quantum sensors and quantum computers to provide grid state estimates, e.g., using quantum tomography “at the edge”. In addition, these quantum devices can be used to compute responses to grid faults and cyberattacks.
