Overview
Aggregate MMC-based VSC-HVDC interconnection with startup sequence, DC voltage regulation, active/reactive power control, and optional DC fault scenario.
This example shows a 1000 MW HVDC interconnection using modular multilevel converter technology. It is one of the strongest flagship models for advanced transmission studies and modern renewable-integration workflows.
The interconnection includes a 400 kV grid equivalent, aggregate MMC converter representation, DC cable subsystem, and full controller set for active power, reactive power, DC voltage regulation, current control, and sequencing.
HVDC is central to modern transmission, offshore wind integration, and long-distance bulk power exchange. This model also helps position SPS Software examples beyond teaching demos into large-scale infrastructure applications.
Key Features
- Aggregate MMC modeling for speed and realism balance
- Startup sequence including capacitor charging and deblocking
- Active and reactive power ramps
- Optional DC cable fault scenario
- Real-time-friendly modeling approach
Getting Started
- Run the 10-second simulation and observe startup events.
- Watch DC voltage rise to nominal operation.
- Track active power ramp to 1000 MW and reactive power ramp to 250 Mvar.
- Optional: set the DC fault time to trigger cable-fault shutdown behavior.
