This paper presents an improved inverter control strategy that is modelled in a PQ reference frame. The Hysteresis Current Control (HCC) is used to provide the switching signals for the inverter power switches.
Strategy I has better transients in frequency, output current, and power. Strategy I reaches steady state faster with overshoots and has a tracking error in the reactive power. Strategy II has good tracking performance for
To address this issue, this paper presents an advanced control approach designed for grid-connected PV inverters. The proposed approach is effective at reducing oscillations in the DC-link voltage at
The efficacy of these control strategies has been tested in a hardware setup of a microgrid fed by two 5kVA 208V droop-controlled inverters, and the results are presented in
To improve the stability of VQ-VSC grid connection, the DC-link capacitor dynamic self-synchronous grid-connected control strategy without using PLL is proposed in this paper.
This study comprehensively analyzes a control technique employed in a single-phase grid-connected photovoltaic (PV) system. The primary objective of this technique is to synchronize the sinusoidal
To meet these requirements, a PQ control structure for the three-phase four-leg grid-connected inverter in a synchronous reference frame based on feedback linearization control ( FLC) is proposed.
For several years, the focus of recent research has been on solar power and distributed generation (DG) systems, these systems have been widely used in various
Proper inverter management in grid-connected PV systems ensures the stability and quality of the electricity supplied to the grid. An appropriate control strategy is necessary to ensure...
