Evaluation of Power Quality Issues in grid Connected PV Systems

Abstract

<p>This paper deals with the evaluation of power quality issues in grid connected PV systems. This paper also presents complete simulation, modeling and control of three phase grid connected solar PV module with Maximum Power Point Tracking. Perturb and Observe (P&O) method has been used for Maximum Power Point Tracking. In the proposed model DC bus voltage control , harmonic mitigation and power factor control are discussed as power quality issues. The simulation results are shown in the graphical waveforms and simulation is performed in MATLAB using SIMULINK environment and PSB toolboxes. <strong> </strong></p>

A Grid-Connected Photovoltaic Interface System for Delivering Active and Reactive Powers

“…In a gridconnected PV system, the PV is commonly interfacing the grid through a voltage source inverter [2]. The major concerns of the PV interface are the efficiency and controllability, including the power quality [3], [4], when it is connected to the grid which not only absorbs active power, but also reactive power. The inverter of PV interface has to be able to operate in reactive power mode, instead of in active power mode [5].…”

Experimental Verification of Single Phase Z Source Inverter for Photovoltaic Applications

“…These inverters have to handle various power quality issues due to PV source fluctuations, which impose stringent requirements for inverter topologies and their controls. [1] - [3] Z Source Inverter (ZSI) employing an impedance network consisting of inductors and capacitors, coupled with inverter main circuit to the variable DC source, which overcomes the voltage fluctuation problems caused by inherent characteristics of the photovoltaic systems. ZSI features a wide range of voltage gain which is suitable for many applications.…”
