## Overview

A PMSG-based aggregated Type 4 wind farm model with back-to-back converters, DC-link regulation, and wind-speed event scenarios.

This example demonstrates an aggregated Type 4 wind farm based on a permanent magnet synchronous generator and back-to-back converter structure. It complements the PV seed models and helps ensure the community launch content covers more than one renewable technology.

The model is useful for studying wind-speed changes, DC-link behavior, reactive power control, and turbine response to voltage events. It also gives renewable developers and grid planners a practical model to build discussion around wind plant EMT studies.

## Key Features

- Aggregated utility-scale wind farm representation
- PMSG-based Type 4 architecture
- Wind-speed and voltage sag scenarios
- Good baseline for wind integration and controller studies

## Getting Started

1. Open Type4\_WindFarm\_33kV.ecf from Renewable Energy
2. Run the default case with nominal wind speed
3. Test wind-speed changes and voltage sag scenarios
4. Review grid power, DC-link regulation, and turbine control response
