Overview
A practical RT-LAB microgrid example with parallel inverters, droop-based active and reactive power sharing, and islanded load-step response.
This RT-LAB starter model demonstrates how multiple inverter-based DER units can share load in an islanded microgrid using classical droop control. It is a strong first upload because it is easy to understand, visually dynamic in runtime, and directly relevant to utilities, research groups, and universities working on resilient distributed power systems.
Microgrids are one of the clearest application areas for real-time simulation because field testing of transitions, unbalanced conditions, and coordinated inverter behavior can be expensive and risky. This example gives the community a practical baseline for discussing control design, tuning tradeoffs, and HIL extensions.
Key Features
- Testing active and reactive power sharing between inverter-based DERs
- Studying islanded microgrid stability under load changes
- Comparing controller tuning choices for P/f and Q/V droop
- Using RT-LAB for real-time controller validation before field deployment
Getting Started
- Open the RT-LAB project and review the inverter control structure.
- Run the model in real time and apply the preconfigured load-step scenarios.
- Monitor bus voltage, frequency, and each inverter active/reactive contribution.
- Adjust droop gains and compare sharing performance.
