Delay Free Real-time Simulation of a Distribution Grid with 650 Nodes, Version with OLTC Transformer

Abstract

This model is a distribution grid with 650 nodes with OLTC transformer. It can run in SSN at a time step in the 80-100µs range in real-time on Xeon V3 based OP5600 target.

This model includes an On-Line Tap Changer (OLTC) transformer made with SSN methodology. The OLTC transformer has a continuously modifiable turn-ratio and leakeage inductance, without explicit switches and thus compatible with real-time simulation.
