Implementing a machine learning-based architecture that analyzes past, current, and future operational characteristics of the power grid to predict load fluctuations, enabling data centers to perform mitigation operations such as adjusting power consumption, storing power, or migrating services to balance the grid and ensure service availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power management systems are used, then data centers can operate with simple infrastructure, but they experience supply voltage instability and cannot anticipate load changes
Solution Approach 1:
The system performs preliminary actions by analyzing historical operational characteristics and current grid conditions to predict future load fluctuations before they occur. This allows the data center to proactively adjust power consumption, store power, or migrate services in advance, preventing voltage instability rather than reacting to it after it occurs.
Solution Approach 2:
The system implements continuous feedback loops where operational characteristics are constantly monitored, analyzed, and used to adjust power management decisions. The machine learning model learns from past performance and refines predictions, creating a closed-loop system that continuously improves reliability while adapting to changing grid conditions.
2Reliability
If machine learning-based prediction is implemented, then load fluctuations can be anticipated and power grid reliability improved, but system complexity increases
Solution Approach 1:
The machine learning system performs self-service by automatically analyzing operational characteristics, generating predictions, and triggering mitigation operations without human intervention. The system self-adjusts power consumption patterns, autonomously decides when to store or release power, and automatically migrates services, reducing the need for complex manual control mechanisms.
Solution Approach 2:
The system changes operational parameters dynamically based on predictions, adjusting power consumption levels, storage discharge rates, and service migration timing. By optimizing these parameters through machine learning rather than using fixed complex control systems, the patent achieves improved reliability with manageable complexity.
3Productivity
If mitigation operations are performed to balance power grid, then service availability is ensured, but operational complexity increases
Solution Approach 1:
The system segments mitigation operations into distinct, manageable types: adjusting power consumption, storing power, and migrating services. Each operation type is handled by specialized components that execute specific functions, simplifying the overall control architecture while ensuring comprehensive service availability through multiple independent mitigation strategies.

AI summary
Improving the operations of a data center that is located within a power grid and that includes its own power sources. Past operational characteristics of the power grid are analyzed to derive learned characteristics for the power grid. Current and/or future operational characteristics of the power grid are also monitored. A prediction regarding an upcoming, anticipated load for the power grid is then generated using the learned characteristics and the monitored characteristics. In response to this prediction, one or more mitigation operations are selected and then performed at the data center to ensure that the data center is adequately available. Some of these mitigation operations include, but are not limited to, causing the data center to consume more power, causing the data center's power sources to store more power, or causing the data center to migrate services and/or data to a different data center.
