Abstract
This work presents two different types of virtual oscillator controllers (VOCs). Unlike droop and virtual synchronous machine (VSM), VOC is a time-domain control technique. Each voltage source inverter (VSI) in this technique is adjusted to replicate the dynamics of the nonlinearly linked oscillators. Because VSIs are electrically linked, their output voltages synchronise and the load is distributed proportionally to their ratings. The authors discussed nonlinear deadzone-based VOC and nonlinear Vanderpol-based VOC. This paper discusses the design and implementation of the aforesaid control techniques. During a load disturbance, the simulation research is done on a 3-phase parallel VSI system using the above-mentioned control techniques. This research examines both equal and uneven power distributions. The suggested control approaches are validated by the simulation results.
