Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional operational tools (ADMS, DERMS) are used for power grid management, then human operation and orchestration are maintained, but the system cannot keep up with the pace of change and timeliness of decision-making
Solution Approach 1:
The system enables autonomous operation where the power grid management system automatically monitors, analyzes, and makes operational decisions without continuous human intervention. The machine learning models self-adjust and optimize grid operations in real-time, allowing the system to serve itself in terms of decision-making while maintaining reliability through continuous learning from historical and real-time data.
2Speed
If pure physics models are used for power grid representation, then data accuracy is maintained, but computational speed is insufficient for real-time operations
Solution Approach 1:
The system merges physics-based models with machine learning models to create a hybrid approach. The physics models ensure data accuracy and physical constraints are met, while the machine learning components provide rapid computational speed for real-time predictions. This combination allows the system to leverage the strengths of both approaches: the interpretability and physical consistency of physics models with the speed and adaptability of ML models.
3Adaptability or versatility
If traditional rules-based management is used, then historical worst-case scenario studies are conducted, but the system cannot adapt to complex and volatile conditions
Solution Approach 1:
The system transitions from static rules-based management to dynamic adaptive management using machine learning models that continuously learn from new data. The models adapt to changing grid conditions, weather patterns, and operational scenarios in real-time, allowing the system to respond flexibly to complex and volatile conditions while maintaining manageable complexity through automated learning rather than manual rule updates.
4Reliability
If human operation and orchestration are relied upon, then operational control is maintained, but human error and inefficiency persist
Solution Approach 1:
The system implements continuous feedback loops where machine learning models monitor grid operations, compare actual performance against predictions, and automatically adjust operations to optimize reliability. The feedback mechanism includes continuous learning from historical data and real-time measurements, allowing the system to identify and correct potential issues before they affect reliability, thereby maintaining high operational standards without human error.
Data Source
AI summary
A system for autonomously facilitating monitoring and orchestration of operations and planning of a power grid includes one or more machine learning models for executing a digital representation of the power, determine operational states of the power grid, and cause the digital representation of the power grid to update based on the determined operational states of the power grid. The system may determine the operational states of the power grid by receiving data associated with a subset of nodes of the power grid and determine the states of each node of the power grid based on the data received associated with the subset.
