Overview

A comparison model for grid-forming inverter control strategies including droop single-loop, droop double-loop, and VSG behavior.

This model is ideal for discussion seeding because it compares multiple grid-forming control strategies on the same microgrid architecture. It gives users a practical benchmark for understanding how different inverter control philosophies affect power sharing, frequency response, and voltage regulation.

It is particularly valuable for R&D teams and researchers studying grid-forming behavior in low-inertia systems or evaluating VSG approaches against more conventional droop-based implementations.

Key Features

  • Compares multiple GFM control strategies in one example
  • Useful for benchmarking droop and virtual synchronous behavior
  • Supports discussion around stability and fault response
  • Good fit for advanced DER and low-inertia system studies

Getting Started

  1. Open the model from the Renewable Energy category
  2. Run the simulation with the default configuration
  3. Compare frequency, voltage, and power-sharing behavior across control modes
  4. Use the model as a benchmark before testing custom GFM variations

Which grid-forming control approach has worked best in your studies so far: droop-based control or VSG-style emulation?

My name is Vincent. I am doing the simulation of Grid Forming Microgrid Control with Smart Inverters. But, how can I change the power sharing ratio between two VSG inverters. Which parameter I can change?

In the case of primary Droop control, both generators have the same parameters (active and reactive Droop coefficients), so the distribution is 50% for each. For example, if the Droop coefficient of IBR1 is 8% and IBR2 is 4%, the first will assume twice the active power of the second. The same applies to the reactive power distribution. In the case of primary VSG control, the parameter to modify the active power distribution is D.
