Creating Models

Step-by-step guide to implementing new device models in ANDES.

Examples Overview

The examples progress from simple to advanced:

Example	Model	Complexity	Key Concepts
Example: Static Model (Shunt)	Shunt	Introductory	Static model, constant impedance behavior
Example: Dynamic Model (BusFreq)	BusFreq	Introductory	Dynamic model, transfer function blocks, signal processing
Example: TGOV1 Turbine Governor	TGOV1	Intermediate	Two implementation approaches (equation vs block), limiters
Example: IEEEST Power System Stabilizer	IEEEST	Advanced	External services, switchers, signal processing chain

Workflow

1. Define ModelData class - Declare parameters

2. Define Model class - Declare variables, services, equations

3. Register with System - Add to model registry

4. Generate code - Run andes prepare

5. Test - Validate against reference implementations
