Evaluating Grid Support Features of Voltage Source Inverter: an Analysis of Direct Power Control

EasyChair Preprint 10916, version 1

Abstract

This paper provides valuable insights into the evaluation of voltage source inverter grid support features, emphasizing the importance of direct power control (DPC) in enhancing grid stability, performance, and robustness. The DPC model is designed in a stationary reference frame, eliminating the need for a phase-locked loop, which is a requirement in conventional vector current control methods. It uses simple feed-forward and feedback control loops to ensure proper power injection into the grid. The results indicate that the DPC exhibits faster dynamic response and is more resilient to changes in grid parasitic elements compared to the classical vector current control model.
