Modeling reference

Use this section to determine how gpf represents each device in a steady-state solution. Each page explains the equations, input fields, control modes, limits, and edge cases for one device family. Solve options can hold any adjustable control at its input value.

The five support outcomes explain how each device affects a solve. The Support matrix lists the outcome for every feature. The Format conformance tables list the fields that gpf reads and writes. The first page defines the conventions used by all device models.

• Conventions
• Phase-domain conventions
• Distribution load models
• Distribution device models
• Buses, loads, shunts, and branches
• Generators
• Voltage droop control
• Transformers
• Switched shunts
• HVDC: line-commutated links
• HVDC: voltage-sourced converter lines
• FACTS devices
• Induction machines
• Area interchange
