1Object-affected harmful factors
If renewable energy power systems are used to generate electrical power, then environmental sustainability is improved, but power output variability increases causing potential power shortages or surpluses
Solution Approach 1:
The system performs preliminary actions by predicting weather conditions and power output in advance using camera-based weather prediction and power prediction components. This allows the data center to proactively schedule computational tasks and manage energy resources before power variability occurs, rather than reacting to shortages or surpluses after they happen.
Solution Approach 2:
The system implements feedback loops where camera images are continuously analyzed to predict weather conditions, which then predict power output, which in turn informs computational resource management decisions. This closed-loop feedback enables continuous adaptation to renewable energy variability, improving reliability while maintaining environmental sustainability.
2Loss of energy
If data centers schedule computational tasks based on predicted power availability, then energy costs are reduced, but system complexity increases
Solution Approach 1:
The camera system serves multiple functions: it captures images for weather prediction, provides data for power output prediction, and enables computational resource scheduling. This multi-functionality reduces the need for separate specialized devices, managing complexity while achieving energy cost reduction through intelligent task scheduling.
Solution Approach 2:
The system uses its own camera-based weather prediction capability to generate power predictions and autonomously schedule computational tasks without requiring external grid information or complex third-party systems. This self-service approach reduces overall system complexity while optimizing energy costs.
3Measurement precision
If localized weather prediction is implemented using cameras, then prediction accuracy is improved, but measurement and detection difficulty increases
Solution Approach 1:
The system replaces complex traditional weather measurement instruments with a camera-based optical system. The camera captures visual information about weather conditions (clouds, sky conditions) which is then processed through image analysis algorithms to predict localized weather. This substitution simplifies the detection mechanism while maintaining or improving prediction accuracy through advanced image processing.
