P/Q Control of Grid-Connected Inverters

2021 18th International Multi-Conference on Systems, Signals & Devices (SSD), 2021
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 applications. In photovoltaic grid-connected (GC) and DG systems, one of the objectives that the grid-connected inverters (GCI) is the control of current coming from the photovoltaic modules or ...

A control strategy for a solar grid-connected inverter

2013 26th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2013
In this paper, the control of a grid-connected inverter is investigated. There are two key control issues that need to be examined. The first is the control of the AC side of the converter to ensure that sinusoidal output waveforms are produced and that the DC bus capacitor voltage that the six-switch bridge see is fixed.

An Optimized Transformerless Photovoltaic Grid-Connected Inverter

IEEE Transactions on Industrial Electronics, 2011
Unipolar sinusoidal pulsewidth modulation (SPWM) full-bridge inverter brings high-frequency common-mode voltage, which restricts its application in transformerless photovoltaic grid-connected inverters. In order to solve this problem, an optimized full-bridge structure with two additional switches and a capacitor divider is proposed in this paper ...

Zero-crossing distortion in grid-connected PV inverters

IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 2003
Zero-crossing distortion has been observed in the ac output current produced by some grid-connected photovoltaic inverters and this can cause a resonant response between the grid impedance and the inverter filter capacitor. In some cases, particularly with large numbers of parallel-connected inverters and with weak grids, the resonance can cause ...

Fuzzy PI Controller for Grid-Connected Inverters

2012
In this paper, a current controller for grid-connected inverter is proposed by using a fuzzy logic control algorithm. In PI controller to control the grid-connected inverter, the gains of PI controller are changed with the aid of the fuzzy logic algorithm in order to get the fast transient performance despite of the input variations and load ...

Grid connected Photovoltaic System Based on SPUC5 Inverter

2021 22nd IEEE International Conference on Industrial Technology (ICIT), 2021
In this paper, a new single-phase grid-connected photovoltaic (PV) system, based on the five-level S-Packed U-Cell (SPUC5) inverter, is presented. This novel topology requires a minimum number of components while providing a maximum number of voltage levels. The Pulse Width Modulation (PWM) controller is applied to the five-level SPUC inverter in order
