Serverless Grid Compliance Pipeline (VDE-AR-N 4110)

Project Overview

This project demonstrates a Cloud-Native approach to Automated Grid Compliance. Instead of running manual load flows on desktop software, this pipeline automatically ingests grid models, performs physics-based simulations in the cloud, and validates results against German Grid Codes (VDE-AR-N 4110).

It addresses the industry need for "Cloud-Bursting", leveraging AWS Lambda to handle peak simulation loads during Redispatch 3.0 calculations without maintaining expensive on-premise hardware.

Architecture

Data Flow:

1. Ingest: Grid models (JSON/Pandapower format) are uploaded to an AWS S3 Bucket.
2. Trigger: The upload event triggers an AWS Lambda function.
3. Simulation: The Lambda function:
   • Loads the grid topology using pandapower.
   • Runs a Newton-Raphson Power Flow calculation.
   • Checks node voltages against the $\pm 10%$ tolerance band defined in VDE-AR-N 4110.
4. Storage: Simulation results and violation flags are stored in Amazon DynamoDB for auditing.

Tech Stack

• Grid Logic: Python, Pandapower, NumPy
• Cloud Infrastructure: AWS Lambda, S3, DynamoDB
• Infrastructure as Code: Boto3 (Python SDK)

Key Features

• Automated Physics: Runs full AC Power Flow (not just DC approximation).
• Regulatory Compliance: Hard-coded logic for VDE 4110 voltage stability checks ($0.90 < V_{pu} < 1.10$).
• Scalability: Capable of processing hundreds of grid scenarios in parallel using Serverless concurrency.

Future Roadmap (Redispatch 3.0)

• Integration with AWS Kinesis for streaming smart meter data.
• Expansion of compliance checks to include line loading (thermal limits).
• Automated generation of "Traffic Light" (Ampelphasen) signals for DSO control rooms.
