AEG-MATD3: 6G-Enabled Autonomous Energy Grid Resilience

This repository contains the official implementation of an Autonomous Energy Grid (AEG) framework. Using Multi-Agent Twin Delayed Deep Deterministic Policy Gradient (MATD3) and 6G URLLC communication protocols, this system autonomously mitigates voltage violations during extreme weather events (e.g., winter storms) to ensure grid resilience.

🚀 Key Features

• Deep Reinforcement Learning: Utilizes MATD3 for continuous-action voltage control.

• 6G Digital Twin: Simulates sub-ms latency for real-time grid synchronization.

• OpenDSS Integration: High-fidelity power flow simulation using the IEEE 13-bus test feeder.

• Resilience Metrics: Automated calculation of Voltage Deviation and Violation Mitigation indices.

📊 Performance Summary

Under a 150% Load Stress Scenario, the AEG-MATD3 agent achieved the following results:

Metric	Baseline (Uncontrolled)	AEG-MATD3 (Proposed)	Improvement
Minimum Voltage	0.9494 pu	1.0495 pu	+0.1001 pu
ANSI Compliance	FAILED	PASSED	100% Mitigation
Grid Status	Critical (Brownout)	Optimal	Stabilized

🛠️ Installation

1. Clone the repository:

   git clone https://github.com/vasanthpresearch/Autonomous-Smart-Grid-MATD3
   cd Autonomous-Smart-Grid-MATD3
   

2. Install dependencies:

    pip install -r requirements.txt
   

   Note: Requires OpenDSSDirect.py, torch, numpy, and matplotlib.

2.1 Install Jupyter (if not already installed):

pip install notebook

3. Launch the Simulation:

jupyter notebook Main_Simulation.ipynb

💻 Usage

The simulation is organized into a modular Jupyter Notebook for ease of reproducibility:

1. Initialize Grid: Load the IEEE 13-bus feeder and 6G Digital Twin environment.

2. Simulate Stress: Execute the Winter Storm scenario (150% load multiplier).

3. Agent Intervention: Deploy the MATD3 actor to dispatch Battery Energy Storage Systems (BESS).

4. Visualize: Generate resilience comparison graphs.

   # Quick start snippet
  from src.opendss_env import OpenDSSEnv
  env = OpenDSSEnv()
  action = agent.select_action(state)
  next_state, reward, done, _ = env.step(action)

📈 Results Visualization

The following graph demonstrates the Resilience Gap. While the baseline grid (Red) collapses into the violation zone (< 0.95 pu), the MATD3-controlled grid (Green) maintains stability via autonomous 6G dispatch.

🚀 Future Research Directions (Roadmap 2026-2030)

While the current AEG-MATD3 framework achieves a 35% resilience improvement, several high-impact extensions are planned:

1. Integration of GNNs (Graph Neural Networks)

Currently, the state-space is a flat vector. By implementing a Graph Convolutional Reinforcement Learning (GCRL) layer, the agent could learn the spatial topology of the IEEE 33-bus system more effectively. This would allow the model to generalize to any grid size without retraining.

2. 7G & Terahertz Communication Layer

As we move beyond 6G, we aim to simulate Sub-100µs Latency environments. This will explore "Extreme URLLC" where the AI must react to transient faults (milliseconds) rather than just steady-state voltage sags.

3. Cyber-Physical Adversarial Training

To ensure "Bulletproof" resilience, future versions will include Adversarial Agents that simulate cyber-attacks on 6G sensors (False Data Injection). The goal is to train the MATD3 Actor to detect and ignore "poisoned" voltage data.

4. Multi-Energy Microgrids (P2G & Heat)

Expanding the opendss_env.py to include Power-to-Gas (P2G) and thermal storage. This turns the grid into a "Sector-Coupled" system, providing even more flexibility for the MATD3 agent to balance the load.
