REALM: Reinforcement Learning for Adaptive Microgrid Load Management with LLM-powered Decision Support
Abstract
A novel framework combining LLM-based reasoning with reinforcement learning to optimize microgrid energy management while adapting to real-world uncertainties. The system uses natural language processing to interpret complex grid conditions and environmental factors, then employs multi-agent RL to coordinate distributed energy resources and storage systems.

Research Gap Analysis
Current approaches lack integration between high-level reasoning capabilities and low-level control optimization, while also struggling with real-world uncertainties and human operator interaction. Existing solutions either focus purely on mathematical optimization or simple rule-based systems.
REALM: Reinforcement Learning for Adaptive Microgrid Load Management
Motivation
Microgrids face increasing complexity with the integration of renewable energy sources, electric vehicles, and dynamic load patterns. Current optimization approaches struggle with real-world uncertainties and often rely on simplified mathematical models that fail to capture the nuanced relationships between various grid components. While recent advances in LLMs and reinforcement learning show promise in complex decision-making tasks, their application to energy systems remains limited and typically siloed.
Proposed Approach
REALM introduces a hybrid architecture that leverages the strengths of both LLMs and reinforcement learning:
- LLM-based Situation Analysis
- Processes diverse inputs including weather forecasts, energy prices, historical usage patterns, and system status reports
- Generates structured representations of system state and potential actions
- Provides natural language explanations for recommended actions
- Multi-Agent RL Framework
- Distributed agents managing different grid components (storage, renewables, loads)
- Hierarchical decision-making structure with coordination mechanisms
- Adaptive reward shaping based on LLM-interpreted system goals
- Online Learning and Adaptation
- Continuous model updating based on real-world performance
- Dynamic adjustment of control strategies using test-time reinforcement learning
- Integration of human operator feedback through natural language interfaces
Expected Outcomes
- 15-25% improvement in energy efficiency compared to traditional methods
- Enhanced stability during unexpected events through adaptive control
- Reduced operational costs while maintaining reliability
- Interpretable decision-making process with natural language explanations
- Scalable architecture suitable for different microgrid sizes and configurations
Potential Applications
- Smart city energy management
- Industrial microgrids with complex load patterns
- Integration of electric vehicle charging infrastructure
- Remote community power systems
- Grid resilience during extreme weather events
Proposed Methodology
Develop a hierarchical system combining LLM-based reasoning for high-level strategy with multi-agent reinforcement learning for tactical control, incorporating test-time adaptation and natural language interfaces for human oversight.
Potential Impact
Could significantly improve microgrid efficiency and reliability while making complex energy systems more manageable for human operators. The approach could be extended to other critical infrastructure management applications.
