MetaCog-DVR: Neural Metacognitive Control for Dynamic Voltage Restoration
Motivation
Power grid stability faces increasing challenges from renewable integration and non-linear loads, while current DVR solutions lack adaptive intelligence in fault response. Recent advances in LLM metacognition for medical decision-making demonstrate how systems can make more reliable decisions by understanding their own uncertainty. This creates an opportunity to apply similar principles to power systems, enabling DVRs to make more robust, self-aware decisions about voltage compensation.
Proposed Approach
The MetaCog-DVR framework introduces a novel hierarchical control architecture:
- Metacognitive Layer
- Implements uncertainty quantification inspired by medical LLM systems
- Continuously evaluates confidence in voltage measurements and fault classifications
- Maintains an adaptive memory of past fault scenarios and their resolutions
- Neural Control Layer
- Fast terminal sliding mode controller enhanced with deep learning
- Real-time optimization of control parameters based on uncertainty metrics
- Multi-objective optimization balancing speed and stability
- Hardware Interface Layer
- Advanced power electronic switching strategies
- Real-time compensation voltage synthesis
- Fault-tolerant operation modes
The system uses a hybrid approach combining:
- Uncertainty-aware decision making from medical AI
- Reinforcement learning for control parameter optimization
